What kind of allergy medicine is safe for dogs

We desire to note that Benadryl is typically istered in the tablet form when prescribed for dogs. Liquid Benadryl can be mixed in with your dog’s food only if your vet deems it safe to do so. Dog owners should consult with their vet first.

Benadryl dosage is based on the dog’s body weight. We own included a general guide for istering Benadryl.

For dog owners who desire a more precise dose, experts tell that 1mg of Benadryl per 1lb of body weight is the way to calculate the quantity of Benadryl that will be safe and effective.

How Much Benadryl Can I Give My Dog

WEIGHT OF THE DOG                    


30lbs or smaller                                

10mg per dose

30 – 50lbs                                         

25 mg per dose

50lbs or over                                     

50mg per dose

The quantity of times you can give the medication to your pet is typically around 2 – 3 times a day, 8 hours apart.

What helpful of allergy medicine is safe for dogs

Benadryl typically takes effect within 30 minutes of istration.

We don’t own to tell you that no two dogs are the same. Every dogs reply differently to new medications in their lives.

Therefore, it is incredibly significant to talk to your veterinarian about the dose that is correct for your specific pooch.

Benadryl Side Effects

As with every medications, Benadryl comes with fairly a few unpleasant side effects.

Benadryl Overdose

Benadryl causes hyperexcitability of the dog’s central nervous system.

It is critical to seek proper medical attention if you ponder that your dog may be experiencing an overdose.

Additional signs of a Benadryl overdose include:

  1. Confusion
  2. Agitation
  3. Dilated pupils
  4. Constipation
  5. Rapid heart rate
  6. Seizures
  7. Irregular heartbeat
  8. Muscle tremors

Additional (More Uncommon) Benadryl Side Effects

  1. Vomiting
  2. Decreased appetite
  3. Increased appetite
  4. Diarrhea

Common Side Effects of Benadryl

  1. Sedation
  2. Hypersalivation
  3. Dry mouth
  4. Increased heart rate
  5. Urinary retention
  6. Rapid breathing

Diphenhydramine Side Effects

Again, we desire to reiterate that diphenhydramine, as the athletic ingredient of Benadryl, comes along with the same risks and potential adverse reactions as Benadryl.

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.

Food Allergies
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.

Flea Allergies
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.

Staphylococcus Hypersensitivity
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.

What helpful of allergy medicine is safe for dogs

Microscopically, there are certain unique changes in the blood vessels of the skin in bacterial hypersensitivity.

When to take it

You may only need to take acrivastine on a day you own symptoms, such as if you own been exposed to something you’re allergic to love animal hair.

Or you may need to take it regularly to prevent symptoms, such as to stop hay fever during spring and summer.

How to take it

Acrivastine doesn’t generally upset your stomach. You can take it whether you own eaten recently or not.

Swallow the capsules whole. Do not chew them.

Always take acrivastine capsules with a drink of water, milk or juice (but do not drink grapefruit juice with acrivastine as you may be more likely to get side effects).


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.

What if I forget to take it?

Take your forgotten dose as soon as you remember, unless it’s almost time for your next dose.

Do not take a double dose to make up for a forgotten dose. Do not take more than 3 capsules in 24 hours.

If you forget doses often, it may assist to set an alarm to remind you. You could also enquire your pharmacist for advice on other ways to assist you remember to take your medicine.


Medicated Baths
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.

What helpful of allergy medicine is safe for dogs

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.

Flea Control
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).

What helpful of allergy medicine is safe for dogs

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.

Hypoallergenic Diets
Allergies develop through exposure, so most hypoallergenic diets incorporate proteins and carbohydrates that your dog has never had before.

What helpful of allergy medicine is safe for dogs

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.

Immunotherapy (Hypo-sensitization)
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.

Environmental Control
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.

Thyroid Medication
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.

What helpful of allergy medicine is safe for dogs

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.

In most cases, people with allergies develop mild to moderate symptoms, such as watery eyes, a runny nose or a rash. But sometimes, exposure to an allergen can cause a life-threatening allergic reaction known as anaphylaxis.

This severe reaction happens when an over-release of chemicals puts the person into shock. Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis.

A second anaphylactic reaction, known as a biphasic reaction, can happen as endless as 12 hours after the initial reaction.

Call 911 and get to the nearest emergency facility at the first sign of anaphylaxis, even if you own already istered epinephrine, the drug used to treat severe allergic reactions. Just because an allergic person has never had an anaphylactic reaction in the past to an offending allergen, doesn’t mean that one won’t happen in the future.

If you own had an anaphylactic reaction in the past, you are at risk of future reactions.

If you or your kid own been prescribed acrivastine, follow your doctor’s instructions about how and when to take it.

What helpful of allergy medicine is safe for dogs

If you bought acrivastine from a pharmacy or store, follow the instructions that come with the packet.

How much will I take?

Acrivastine comes as capsules (8mg). The usual dose in adults and children aged 12 years and over is 1 capsule 3 times a day.

When it’s mixed with a decongestant, each capsule contains 8mg of acrivastine and 60mg of pseudoephedrine. The usual dose in adults and children aged 12 years and over is 1 capsule 3 times a day.

Do not take more than 3 acrivastine capsules, or 3 acrivastine mixed with pseudoephedrine capsules, in 24 hours.

What if I take too much?

Acrivastine is generally extremely safe.

Taking too much is unlikely to harm you. If you take an additional dose by error, you might get some of the common side effects.

If this happens or you’re concerned, contact your doctor.

Allergies are an overreaction by your immune system to a substance or food that is not considered harmful to most other people. Substances that cause allergies are called allergens or “triggers”.

What is Benadryl — Understanding the Favorite Medicine

Most dog owners own likely heard of Benadryl. It is an incredibly favorite medication that is used primarily for alleviating seasonal allergies.

Scientifically speaking, Benadryl is an antihistamine that blocks the H1 receptors on the blood vessels and smooth muscle. H1 receptors are histamine receptors that frolic an significant role in the allergic response. By blocking this receptor, Benadryl reduces symptoms of allergic reactions.

Additionally, Benadryl has been used to treat motion sickness in dogs and provide mild sedation.

Although numerous veterinarians consider Benadryl to own a wide safety margin, there are still dangers and adverse reactions associated with the drug that pet owners should be aware of.

What is Diphenhydramine

Benadryl is the brand name for the athletic ingredient diphenhydramine HCl.

Diphenhydramine is categorized as a first-generation antihistamine, meaning that it can cross the blood-brain barrier.

The blood-brain barrier protects the brain from harmful foreign substances, such as bacteria or viruses. This barrier does permit some substances, such as diphenhydramine, to pass through.

Diphenhydramine’s ability to cross the blood-brain barrier means that it is typically extremely effective. However, this abilityincreases the risk of potential adverse reactions.

Benadryl Ingredients

Diphenhydramine is the most athletic ingredient found in Benadryl. As an antihistamine, diphenhydramine reduces the effects of the chemical histamine within the dog’s system.

Benadryl for Dogs — Is It Safe?

Although Benadryl has been deemed to be safe when used appropriately, there are a few things that dog owners should be aware of.

When to Avoid Benadryl

Dogs with glaucoma, high blood pressure, and cardiovascular disease should avoid Benadryl, as it can worsen their condition.

Furthermore, dogs with the following conditions should not get Benadryl:

  1. Nursing
  2. Pregnancy
  3. Angle-closure glaucoma
  4. Prostatic hypertrophy
  5. Bladder neck obstruction
  6. Heart failure
  7. Allergic lung disease
  8. Hyperthyroidism
  9. Seizures

What is Benadryl Used For?

As most pet owners know (due to their own use of Benadryl), the drug is most commonly used to alleviate allergies.

However, what some individuals may not realize is that this favorite medication has several other uses.

Treating Mast Cell Tumors with Benadryl

Mast cells are white blood cells that frolic a role in allergic reactions.

When a dog has mast cell tumors, there is a mast cell degranulation, which causes a massive histamine release.

If your dog has a mast cell tumor, your veterinarian may recommend Benadryl to alleviate symptoms from the histamine release from the tumor cells.

Benadryl for Motion Sickness

Many pet owners may not know that Benadryl is often recommended for dogs who experience motion sickness.

Benadryl for Allergies

We’ll start with the basics.

When we ponder about allergies, we typically ponder about red and itchy eyes, a runny nose, sneezing, etc.

Dogs own diverse symptoms when experiencing allergic reactions.

In most cases, dogs show allergy symptoms on the skin’s surface. Although it is possible for Fido to show signs of allergies that are similar to those of humans, you’ll desire to make certain that your pup doesn’t own a more serious condition at hand.

Nasal discharge, coughing, and inflamed eyes can be a sign of a slew of conditions in dogs, including respiratory infections. Therefore, it is significant not to automatically assume that allergies are causing these symptoms.

The bottom line is that your dog can absolutely suffer from allergies.

Your veterinarian may recommend Benadryl to alleviate your dog’s allergy symptoms.

Allergies in dogs include:

  1. Allergic reactions to snake bites
  2. Environmental allergies
  3. Seasonal allergies
  4. Food allergies
  5. Allergic reactions to insect bites

Unfortunately, despite how badly we wish it were possible, we aren’t exactly capable to communicate with our dogs in a clear, concise way. They can’t let us know when something in the air, or in their food, is making them feel funny.

We also can’t describe to them how badly ant bites feel and tell them to avoid those fun-looking mounds in the grass.

For this reason, knowing that Benadryl is safe for dogs (to a degree) makes numerous dog owners feel at ease if their adventurous pup is prone to itchy situations.

With that said, we desire to stress that, as in humans, allergies and other conditions can be mistaken for one another.

For example, you’ll desire to ensure that your pup is suffering from allergies and not a skin infection, as Benadryl is not an effective way to treat skin conditions.

Your veterinarian will be capable to determine whether your dog has an allergy or skin infection.

Benadryl in Heartworm Treatment

Heartworm treatment involves the killing of adult heartworms. The death of the heartworms can trigger a serious allergic reaction. If your pup has to undergo heartworm treatment, your vet may recommend Benadryl to ease the symptoms associated with the treatment.

Benadryl for Hives

Benadryl is also known to effectively treat hives in both dogs and humans.

In dogs, most cases of hives are merely due to allergic reactions of one helpful or another.

In humans, hives can be a symptom of several underlying medical conditions, so treating it with a medication such as Benadryl will work for the immediate relief, but not as a long-term treatment and certainly not as a cure.

Although pets with hives may glance beautiful miserable, we desire to implore pet owners not to panic if Fido breaks out in hives, as the hives can be treated, typically without any complications.

Benadryl for Anxiety

A major side effect of diphenhydramine, the athletic ingredient in Benadryl, is drowsiness.

If your pup has anxiety, your veterinarian may prescribe Benadryl to assist ease symptoms of anxiety and effectively assist your anxious pup calm down.

When to Call The Vet — Allergic Reactions

Many veterinarians and pet owners discover Benadryl to be an effective antihistamine for mild to moderate allergic reactions.

However, if your pup is having an acute allergic reaction with facial swelling or difficulty breathing, it is imperative that you go straight to the vet.

Benadryl is not effective in serious cases of allergic reactions. Seeking medical intervention in a timely manner is extremely significant for your dog’s life if he’s having a serious allergic reaction.
