What are allergy symptoms in dogs
Common symptoms of an allergic reaction include:
- sneezing and an itchy, runny or blocked nose (allergic rhinitis)
- a raised, itchy, red rash (hives)
- swollen lips, tongue, eyes or face
- wheezing, chest tightness, shortness of breath and a cough
- itchy, red, watering eyes (conjunctivitis)
- tummy pain, feeling ill, vomiting or diarrhoea
- dry, red and cracked skin
The symptoms vary depending on what you’re allergic to and how you come into contact with it.
For example, you may have a runny nose if exposed to pollen, develop a rash if you own a skin allergy, or feel sick if you eat something you’re allergic to.
See your GP if you or your kid might own had an allergic reaction to something.
They can assist determine whether the symptoms are caused by an allergy or another condition.

Gnawing on their paws love you swear they were covered in peanut butter? Enough jingle jangle from scratching around their collar it sounds love Santa is coming? Watery eyes, red ears and incessant sneezing?
Sounds love it might be allergy season for your pup.
Just love in humans, seasonal and environmental allergies can cause discomfort and be a problem for dogs. Unfortunately, identifying these symptoms as allergies isn’t always easy.
Since your dog can’t exactly tell you what’s incorrect, it’s up to pet parents to glance for the signs.
So, how can you tell if your precious pup might be suffering from allergies?
We consulted with Doctor of Veterinary Medicine and one of our Veterinary Advisory Board members Kim Carvalho to discover out. Carvalho is a Board-Certified Diplomate of the American Board of Veterinary Practitioners and is a Clinical Professor at Western University’s College of Veterinary Medicine in Pomona, Calif. She currently serves as one of the Medical Directors.
First a little about allergies.
If you desire to give your dog an antihistamine, love Benadryl, here are some things to consider:
- While typically safe, every dog reacts differently to antihistamines, according to the VCA.
They may cause drowsiness in some dogs and hyperactivity in others.
- If you purchase an over the counter medicine for your dog, check the label to make certain it doesn’t contain any other ingredients love decongestants or pseudoephedrine, which are NOT safe for dogs.
- It’s also significant to note that dosage for humans and dogs will not be the same.
We recommend talking to your veterinarian before giving your dog any over-the-counter medication to ensure the dose is precise and that there are no adverse reactions with any other medications they may be taking.
How to assist prevent an allergic reaction?
Unfortunately, there’s no cure for allergies.
You can’t prevent your dog from having allergies.
However, there are things you can do to assist hold their symptoms and discomfort under control.
First, you own to identify the underlying cause, be it seasonal, food, flea, etc. From there you can assist your dog avoid those allergens.
Carvalho explained that sometimes a prescription diet could be necessary along with using flea/ectoparasite control every year circular. Pet owners should also hold an eye out for and treat any itches so that they don’t lead to inflamed and infected skin and ears.
Because excellent health for your canine companion is always in season (unlike pollen, thankfully).
How are seasonal allergies diagnosed?
Identifying seasonal allergies can be hard because both seasonal and environmental allergies can own similar symptoms explained Carvalho.
Dogs with food allergies can own symptoms that manifest in the skin and in the gastrointestinal tract (i.e. diarrhea).
There are diverse ways that seasonal allergies can be diagnosed, according to PetMD. One common method is an intradermal skin test.
Very similar to allergy testing in humans, with this method, a little quantity of test allergens are injected under your dog’s skin. Allergens are then identified by which injections cause redness, swelling and hives.
Using those results, your vet can create a specialized serum or immunotherapy shot that can be istered by the vet or at home.
Your vet may recommend other ways to diagnose the cause of your dog’s allergies depending upon their symptoms.
What are allergy symptoms?
Dogs often react to allergies by scratching or biting to attempt and relieve itching which can them lead to redness and inflammation.
Here are symptoms to glance for:
- Watery eyes
- Hair loss Itching Ear infections
- Smelly and/or “dirty” ears
- Itchy flaky skin (pruritus)
- Respiratory congestion
- Shaking their head and scratching one or both ears
- Licking of the paws and anus
- Runny nose
- Patchy skin or skin irregularities
How to tell if your dog has seasonal allergies versus food allergies?
“It can sometimes be hard to tell whether a dog has seasonal vs food allergies,” said Carvalho.
“Seasonal allergies tend to be a certain time of year, historically spring or drop.
However with severe changes in our weather pattern, I’m seeing a continuation of seasonal allergies in southern California.”
Food allergies tend to be year circular, but the sudden onset of symptoms, can make it hard to tell.
Plus, when it comes to food, even if you haven’t changed anything in your dog’s diet, there’s always the chance that your food manufacturer may own changed their formula. The new ingredients could be causing a reaction.
How to assist your dog feel better?
If your dog has ongoing symptoms, you notice a change in their behavior and/or you just feel concerned, we always recommend taking your little one to the vet.
With environmental/seasonal allergens it can be hard if not impossible to identify and remove triggers.
“Over the counter antihistamines such as Benadryl (diphenhydramine), Claritin (loratadine), Zyrtec (cetirizine) own been used.
Frequent bathing can assist as well, and of course, for severe allergic patients, prescription medication is used for itching love Prednisone, Cytopoint, Apoquel and antibiotics/anti-yeast medication for secondary infections,” said Carvalho.
What are natural remedies to assist relieve allergy symptoms for dogs?
Just love with humans, figuring out other ways to assist relieve allergy symptoms for your dog can take some trial and error.
Here are a few recommendations:
- Fatty acid supplements: These can assist soothe itchy and irritated skin, according to the NASC.
- Regular bathing with hypoallergenic shampoos: This can assist remove possible allergens love pollen and grass that your dog may come in contact with as part of your daily routine.
- More ways to help: Some people use remedies love tea tree oil, coconut oil, fish oils or other omegas and oatmeal shampoo, according to Carvalho.
At SmartyPaws, our multifunctional health supplements include omega-3 EPA & DHA fatty acids (from fish oil) and organic turmeric.
These ingredients support a normal inflammatory response and dogs with seasonal and environmental allergies.
We also use additional omegas, including omega-3 ALA from organic chia seeds and alfalfa, to assist promote healthy skin, maintain normal moisture content and support animals with sensitive skin.
In addition to providing support for dogs with seasonal and environmental allergies and sensitive skin, our SmartyPaws chews support joint, gut, immune and urinary tract health — every in one simple serving.
So what’s causing the allergic reaction?
Just love humans, a large number of substances can be allergens, and each dog is allergic to diverse things, according to Carvalho.
Some common environmental allergens are:
- Flea saliva
Also, just love humans, dogs can own food allergies too.
In this article we’re focusing on seasonal allergies. However, if you notice any of the under symptoms, we always recommend seeing your vet for a proper diagnosis as both food and environmental allergens can cause similar reactions.
How common are allergies in dogs?
Whether it’s from the environment or food, allergies are common in pets. So, there’s a excellent chance your dog might own them.
What might cause an allergic reaction doesn’t tend to change with age, but certain breeds are more predisposed to allergies than other breeds, said Carvalho.
Dog skin allergies
According to the American Kennel Club, skin allergies are the most common type of allergic reactions in dogs.
Environmental allergens are one of the main causes.
Dust, pollen, and mold are every environmental allergens (among other triggers) that can cause allergic reactions or atopic dermatitis.
Often times, these are seasonal. So you may only notice your dog itching during certain times of the year.
The most commonly affected areas are the paws and ears, but the wrists, ankles, muzzle, underarms, groin, eyes and in between the toes may also be affected.
One concern with skin allergies is that they can lead to secondary infections.
Your dog may attempt to scratch, bite or lick his or her skin for relief which can then make him or her susceptible to yeast and bacterial infections.
Is there an allergy-free dog?
While poodles, Portuguese water dogs and a number of other breeds (including several types of terriers) own a reputation for being hypoallergenic, a truly allergy-free breed does not exist.
A 2011 study compared dust samples from homes with dog breeds reported to be hypoallergenic and those of homes with other dogs. The levels of dog allergen in homes with “hypoallergenic” dogs did not differ from the levels in homes with other breeds.
This sheet was reviewed for accuracy 4/23/2018.
One of the most common medical complaints that we see in our office is dogs with skin infections, “hot spots”, or allergic dermatitis, also known as atopic (atopy) dermatitis.
Unlike people who react to allergens most commonly with nasal symptoms and/or hives, dogs react with skin and/or gastrointestinal problems.
This is because there are a higher proportion of mast cells, which release histamines and other vasoactive substances in the face of an allergic challenge, in the skin of dogs. These problems may range from poor jacket texture or hair length, to itching and chewing, to boiling spots and self-mutilation, gastrointestinal pain and discomfort, diarrhea, and flatulence. Allergies may also frolic a part in chronic ear infections. The most common causes of canine allergic dermatitis are flea allergy, food allergy, inhalant or contact allergy, and allergy to the normal bacterial flora and yeast organisms of the skin.
To make matters more hard to diagnose and treat, thyroid disease may add to the problem as well.
Canine atopic dermatitis (allergic dermatitis, canine atopy) is an inherited predisposition to develop allergic symptoms following repeated exposure to some otherwise harmless substance, an “allergen”.
Most dogs start to show their allergic signs between 1 and 3 years of age. Due to the hereditary nature of the disease, several breeds, including Golden Retrievers, most terriers, Irish Setters, Lhasa Apsos, Dalmatians, Bulldogs, and Ancient English Sheep dogs are more commonly atopic, but numerous dogs, including mixed breed dogs can own atopic dermatitis. Atopic animals will generally rub, lick, chew, bite, or scratch at their feet, flanks, ears, armpits, or groin, causing patchy or inconsistent hair loss and reddening and thickening of the skin.
The skin itself may be dry and crusty or oily depending upon the dog. Dogs may also rub their face on the carpet; ear flaps may become red and boiling. Because the wax-producing glands of the ear overproduce as a response to the allergy, they get bacterial and yeast (Malassezia ) infections of the ear.
In order to overcome these frustrating symptoms, your veterinarian’s approach needs to be thorough and systematic. Shortcuts generally will not produce results and only add to owner frustration and canine discomfort.
Inhalant and Contact Allergies
Substances that can cause an allergic reaction in dogs are much the same as those that cause reactions in people including the pollens of grasses, trees and weeds, dust mites, and molds.
A clue to diagnosing these allergies is to glance at the timing of the reaction. Does it happen year round? This may be mold or dust. If the reaction is seasonal, pollens may be the culprit.
Numerous people don’t suspect food allergies as the cause of their dog’s itching because their pet has been fed the same food every its life and has just recently started having symptoms. However, animals can develop allergies to a substance over time, so this fact does not law out food allergies. Another common misconception is that dogs are only sensitive to poor quality food.
If the dog is allergic to an ingredient, it doesn’t matter whether it is in premium food or the most inexpensive brand on the market. One advantage to premium foods is that some avoid common fillers that are often implicated in allergic reactions.
This type of reaction generally is not to the flea itself, but rather to proteins in its saliva. Interestingly enough, the dogs most prone to this problem are not dogs who are constantly flea ridden, but those who are exposed only occasionally! A single bite can cause a reaction for five to seven days, so you don’t need a lot of fleas to own a miserable dog.
Bacterial hypersensitivity occurs when a dog’s immune system overreacts to the normal Staphylococcus (Staph) bacteria on its skin.
It appears that bacterial hypersensitivity in the dog is more likely to happen if other conditions such as hypothyroidism, inhalant allergy, and/or flea allergy are concurrently present. Bacterial hypersensitivity is diagnosed through bacterial culture and examination of a biopsy sample. Microscopically, there are certain unique changes in the blood vessels of the skin in bacterial hypersensitivity.
Allergy testing is the best diagnostic tool and the best road to treatment for dogs that are suffering from moderate and severe allergies. There are several diverse testing methods available. The most common is a blood test that checks for antigen induced antibodies in the dog’s blood.
Intradermal skin testing may also be performed. In this method of testing, a little quantity of antigen is injected into a shaved portion of the dog’s skin. This is done in a specific pattern and order so that if the dog shows a little raised reaction, the offending antigen can be identified. After a period of time (hours), the shaved area is examined to detect which antigens, if any, created a reaction. Allergy testing is performed to develop a specific therapy for the allergic animal.

Avoidance is the best way to manage a dog allergy.
If you own a dog and are allergic to dogs, consider removing the dog from the home.
If you own a dog but don’t desire to discover it a new home, or if your family wants a dog even though someone in the household is allergic, here are some strategies that may assist hold symptoms at bay:
- Keep the dog out of your bedroom and restrict it to only a few rooms. Be advised that keeping the dog in only one room will not limit the allergens to that room.
- High-efficiency particulate air (HEPA) cleaners run continuously in a bedroom or living room can reduce allergen levels over time.
- Regular use of a high-efficiency vacuum cleaner or a central vacuum can reduce allergen levels.
- Don’t pet, hug or kiss the dog; if you do, wash your hands with soap and water.
- Giving your dog a bath at least once a week can reduce airborne dog allergen.
Treatments for dog allergy vary, depending on the symptoms.
Your allergist can assist determine what treatment would be best to treat your dog allergy.
Nasal symptoms are often treated with steroid nasal sprays, oral antihistamines or other oral medications. Eye symptoms are often treated with antihistamine eyedrops. Respiratory or asthma symptoms can be treated with inhaled corticosteroids or bronchodilators to either prevent or relieve respiratory symptoms.
Allergy shots (immunotherapy) are an effective treatment of allergies by building tolerance over time through gradually injecting increasing doses of an allergen.
What are allergies?
Allergies are sensitivities to things found in our everyday environments love dust and pollen, according to the National Animal Supplement Council (NASC).
Typically, these things aren’t harmful to dogs (or humans).
Yet, your immune system may feel differently and react to an otherwise harmless substance as dangerous. Normally, the immune system protects your dog from infection and disease, but when it comes to allergies the immune system can actually be harmful to the body, according to the VAC.
When this happens the immune system responds by releasing histamines that can cause inflammation, swelling and itching. Inflammation then causes the various signs associated with an allergic reaction.
Numerous medicated shampoos own compounds in them that are aimed at soothing injured skin and calming inflammation.
In addition, frequent bathing (weekly to every other week) of the dog can remove allergens from the hair jacket, which may contribute to skin allergy flare-ups. The medicated baths we recommend are those that actually contain antimicrobial and antifungal agents as well as ingredients that permit the skin to be bathed on a more frequent basis without drying it out. Application of a rinse afterwards also helps to prevent drying out of the skin and hair coat.
Antihistamines can be used with excellent safety in dogs.
About one third of owners report success with antihistamines. These medications tend to own a variable effect between dogs. For some allergic dogs, antihistamines work extremely well in controlling symptoms of allergic skin disease. For other dogs, extremely little effect is seen. Therefore, a minimum of three diverse types of antihistamines should be tried before owners give up on this therapy. Examples of antihistamines commonly used for dogs include Benadryl, Chlortrimeton, Atarax, Claritin, Zyrtec, and Clemastine. However, antihistamines are considered to be worth trying in most cases since the side effects associated with antihistamines is low, and they are typically inexpensive medications.
Antibiotics and Antifungal Medications
Antibiotics are frequently needed to treat secondary skin infections.
Anti-fungal medications are frequently needed to treat secondary yeast infections.
For dogs with this problem, a strict flea control regime must be maintained. The best flea control options include the use of products such as Advantage, Revolution, Frontline, Comfortis, and Sentinel.
The Omega-3 and Omega-6 essential fatty acid supplements work by improving the overall health of the skin. These fatty acids are natural anti-inflammatory and anti-oxidative agents. They reportedly are helpful in 20% of allergic dogs. My own experience puts this figure a little higher.
They are certainly worth a attempt because they are not harmful and own virtually no side effects. Omega-3 fatty acids are found in fish oils and omega-6 fatty acids are derived from plants containing gamma-linolenic acid (GLA). These supplements are diverse from those sold to produce a glossy jacket. Products that contain both omega-3 and omega-6 fatty acids include Allergen Caps and Halo.
Allergies develop through exposure, so most hypoallergenic diets incorporate proteins and carbohydrates that your dog has never had before.
As mentioned previously, the quickest and best way to determine which foods your dog may or may not be allergic to is through diagnostic allergy testing. As dairy, beef, and wheat are responsible for 80% of food allergies in dogs, these items should be avoided. Novel protein sources used in hypoallergenic diets include venison, egg, duck, kangaroo, and types of fish not generally found in pet food. Carbohydrate sources include potatoes, peas, yams, sweet potatoes, and canned pumpkin.
Hydrolyzed protein diets are diets in which the protein source has been synthetically reduced to little fragments. The theory behind feeding a hydrolyzed protein source is that the proteins in the food should be little enough that the allergic dog’s immune system will not recognize the protein fragments and will not mount an immune response resulting in an allergy.
Most pets with food allergies reply well when switched to a store-bought hypoallergenic diet, but occasionally an animal suffers from such extreme allergies that a homemade diet is the only option.
In this case, the diet should be customized with the aid of a veterinarian.
Corticosteroids and Immunosuppressive Agents
Cortisone products such as prednisone, prednisolone, and dexamethasone reduce itching by reducing inflammation. These medications are not without side effects, so they need to be used judiciously in treating skin allergies. Steroids should be considered only when the allergy season is short, the quantity of drug required is little, or to relieve a dog in extreme discomfort.
Side effects can include increased thirst and appetite, increased need to urinate, and behavioral changes. Long-term use can result in diabetes and decreased resistance to infection. In some dogs, endless term, low-dose alternate day therapy is the only management protocol that successfully controls the atopic pet. This protocol should be used only as a final resort after every other methods own been exhausted to avoid the potential long-term complications of the medication.
Cyclosporine (Atopica) is a medication, which seems to be fairly effective at reducing the inflammation associated with skin allergies and calming the immune system of the affected dog.
However, the pricing of cyclosporine may be prohibitive for larger breed dogs.
Allergy shots are extremely safe, and numerous people own grand success with them; however, they are extremely slow to work. It may be six to twelve months before improvement is seen. Once the allergens for the dog are identified, an appropriate immunotherapy is manufactured for that specific dog, and treatment can start.
After the offending antigens are identified, then a mixture of these antigens can be formulated into a hyposensitizing injection. Depending on the type of agents used, these injections will be given over a period of weeks to months until the dog or cat develops immunity to the agents. After initial protection, an occasional booster may own to be given.
If you know which substances your dog is allergic to, avoidance is the best method of control. Even if you are desensitizing the dog with allergy shots, it is best to avoid the allergen altogether.
Molds can be reduced by using a dehumidifier or placing activated charcoal on top of the exposed dirt in your home plants. Dusts and pollens are best controlled by using an air cleaner with a HEPA filter. Air conditioning can also reduce circulating amounts of airborne allergens because windows are then kept closed.
Healthy skin and a normal hair jacket are the results of numerous factors, both external and internal. There are several glands in the body responsible for the production of hormones that are vital for the regulation of other body functions as well as a normal skin surface and hair jacket. Hypothyroidism may result in poor skin and hair jacket, including hair loss or abnormal hair turnover, dull or brittle hair, altered pigmentation, and oily or dry skin.
A blood test is a simplest and most direct way to tell if your dog is hypothyroid. Thyroid testing may include every or part of the following:
Baseline T4 Test or Entire T4 (TT4): This is the most common test. Dogs with a failure of the thyroid gland will own a lowered level of the T4 hormone. However, there are other conditions that can cause the T4 to decrease, so if this test comes back positive for hypothyroidism your vet should recommend an additional blood test, either the T3 Test or the Baseline TSH test.
Baseline TSH Test: Measures the level of Thyroid Stimulating Hormone.
In combination with the T4 or T3 test, it provides a more finish picture of the hormonal activity of your dog’s thyroid gland.
Free T4 by RIA (radio immunoassay): The Free T4 test using RIA techniques does not appear to be more or less precise than the above TT4 test.
Free T4 by ED (equilibrium dialysis): This test may provide more precise data on the level of T4 hormone in your dog’s bloodstream.
Baseline T3 Test: In combination with the T4 or TSH test, these two blood tests can give a clearer picture of the hormone levels found in the bloodstream.
This test is not dependable when used alone. The T3 Test should always be given in combination with one of the other blood tests.
TSH Response Test: In this test, the veterinarian takes an initial measurement of the thyroid hormones in your dog’s bloodstream and then injects Thyroid Stimulating Hormone (TSH) into the vein. After 6 hours, a blood sample is drawn and the level of T4 is checked. If your dog has hypothyroidism, the level of T4 will not increase even after the TSH is injected. This is an expensive test and is being used less often due to decreased production by the manufacturers.
Hypothyroidism is treated with a daily dose of synthetic thyroid hormone called thyroxine (levothyroxine).
Blood samples will need to be drawn periodically to assess the effectiveness of the dosage and make any adjustments necessary.
Successful management of the atopic, allergic dog is sometimes complicated and frustrating because multi-modal management is necessary in the majority of cases to control the allergic flare-ups. Proper diagnosis by a veterinarian and owner compliance and follow up care is essential to maximize the chances of curing or at least controlling the severely affected allergy patient.
Reduce the allergens and your symptoms
If you are allergic to your pet and your reactions aren’t life-threatening, there are numerous ways to reduce indoor allergens and allergy symptoms so you and your pet can live together more comfortably.
If your or a family member’s allergies are simply miserable, but not life-threatening, take these five steps to reduce the symptoms:
Create an «allergy free» zone in your home—preferably the allergic person’s bedroom—and strictly prohibit the pet’s access to it. Use a high-efficiency HEPA air cleaner, and consider using impermeable covers for the mattress and pillows.
2. Use HEPA air cleaners throughout the relax of the home, and avoid dust-and-dander-catching furnishings such as cloth curtains and blinds and carpeted floors. Clean frequently and thoroughly to remove dust and dander, washing articles such as sofa covers and pillows, curtains, and pet beds.
3. Bathe your pet on a weekly basis to reduce the level of allergy-causing dander (shed ancient skin cells).
Cats can get used to being bathed, but it’s critical to only use products labeled for them; kittens may need a shampoo safe for kittens. Check with your veterinarian’s staff or a excellent book on pet care for directions about safe bathing, It’s a excellent thought to use a shampoo recommended by your veterinarian or other animal care professional.
4. Don’t be quick to blame the family pet for allergies. Enquire your allergist to specifically test for allergies to pet dander.
Numerous allergy sufferers are sensitive to more than one allergen. Reduce the overall allergen level in your environment by concentrating on every of the causes, not just the pet allergy.
5. Attempt treatments. Additional treatments for allergies to pets are include immunotherapy (allergy shots), steroidal and antihistamine nose sprays and antihistamine pills. It is significant to discover an allergist who understands your commitment to living with your pet. A combination of approaches—medical control of symptoms, excellent housecleaning methods, and immunotherapy—is most likely to succeed in allowing an allergic person to live with pets.
Severe allergic reaction (anaphylaxis)
In rare cases, an allergy can lead to a severe allergic reaction, called anaphylaxis or anaphylactic shock, which can be life threatening.
This affects the whole body and usually develops within minutes of exposure to something you’re allergic to.
Signs of anaphylaxis include any of the symptoms above, as well as:
Anaphylaxis is a medical emergency that requires immediate treatment.

Millions of people enjoy sharing their homes and their lives with pets, even those who are allergic to animals. Unfortunately, some people believe that once they are diagnosed with a pet allergy, they own no choice but to remove their pets from their family.
Thankfully, there are numerous solutions that can be explored that would permit an allergy sufferer to hold their beloved pets while successfully managing their allergies.
You’d be surprised to know how numerous people with allergies that aren’t life-threatening are capable to live happily with their pets.
In numerous cases, the benefits of having a pet outweigh the drawbacks of pet allergies.
Understand your pet allergies
It is significant to see a doctor and be tested to determine what allergies you actually own. You may discover that you’re allergic to something else and not your pet at all! For example, you may assume that you are allergic to your beloved dog, only to discover out through an allergy test that you’re actually allergic to a specific tree pollen that got on his fur during a stroll together, and that’s actually what’s bothering you.
If an allergy test shows that you are allergic to your pet, it is significant to understand what causes your allergic reaction to them.
There are allergy-triggering proteins called allergens in saliva and skin glands that cling to an animal’s dry skin (dander) and fur. The fur and dander then stick to walls, carpets and clothing.
The reaction of someone to these allergens is diverse from one person to the next. The reaction may range from mild sniffling and sneezing to life-threatening asthma. The reaction can be made worse if a person is additionally exposed to other things he is allergic too, such as pollen, dust mites, cigarette smoke, and mold.
Whether someone has an allergic reaction depends on both the individual person and the individual animal. A person with animal allergies may react less to dogs with soft, constantly growing hair, or one specific cat or dog may cause more or less of an allergic reaction than another animal of that same breed.
You may hear claims about breeds of dogs and cats that are non-allergenic (don’t cause an allergic reaction) or cats and dogs that are hypoallergenic (cause less of an allergic reaction).
However, even hairless breeds may cause a severe allergic reaction.
