My dog has allergies what can i give her
Malnutrition can affect enterocyte structure and function. A poorly functioning or damaged enterocyte can let whole proteins into the body. Once a whole protein has managed to breach every of the gut’s defenses, gut-associated lymphoid tissue (GALT) takes over. GALT can prevent the body’s natural immune response to a foreign protein. Most of the time this is what happens, but in the case of food allergies, GALT does not prevent the immune response and an allergic response (immune hypersensitivity) is formed.
Unfortunately, every time the food is eaten, this over-response of the immune response becomes greater.
So continuing to consume the diet that caused the allergic response results in a greater and greater response every time. After this hypersensitivity is formed, each time the dog eats the food, mast cells in the body’s immune system release hertamine. If this hertamine release is large enough, it may manifest as diarrhea, itchy skin, chronic skin infections etc.
Isolating the Problem
The first thing you need to do is work with your veterinarian to make certain that your dog’s symptoms truly indicate a food allergy. If that’s the case, your vet will likely recommend that you attempt an elimination diet— feeding a food that has a diverse protein (meat) source and a diverse carbohydrate (grain) source than what your dog has had before.
Common anti-allergy foods (novel protein sources) include kangaroo and oatmeal or venison and potato. This prevents the immune response from continuing to be triggered.
Your vet may also propose that you attempt a hypoallergenic diet.
These foods are made with hydrolyzed proteins. That means that the proteins are already broken below into pieces that are little enough that IgA won’t bind to them and they won’t trigger an immune response.
Lamb and rice foods used to be considered “hypoallergenic” when most commercial dog foods were made with chicken or beef and corn or wheat. Since most dogs had never had lamb or rice before, it was a excellent option for dogs that experienced allergies while eating a regular food.
Now, however, numerous dogs are showing allergies to lamb and rice diets.
This is to be expected since an allergy can develop to any diet. If your dog is allergic to lamb and rice you may need to discover a food with diverse ingredients such as fish and oatmeal, or venison and sweet potato.
While your dog is on any special diet, it’s extremely significant that she doesn’t get any other food such as cookies, treats, rawhides, people foods, etc. Since you don’t know yet exactly what she is allergic to, you don’t desire to give her something other than her food and trigger the allergic reaction.
Once you’ve got her on a food that she is not reacting to, you can start to reintroduce other foods. If your dog reacts, you’ll know exactly which food (or foods) causes the problem.
The Gut and Immune System Together
Prevent Food Allergies
IgA cells are a type of immune cell secreted in the intestine. Some of the IgA will float freely in the contents of the intestine while other IgA attaches to the wall of the intestine to prevent whole protein from coming in contact with the enterocytes.
Just love volleyball players they bounce whole proteins back into the contents of the intestine for more digestion. The more effective protein digestion in the stomach and intestine is, the smaller the proteins are when they come in contact with the IgA. Little proteins and single amino acids do not get bound to the IgA and are allowed to pass by the IgA and be absorbed into the body as nutrients.
At a Glance
Some of the breeds most prone to food allergies include: Boxer, Cocker Spaniel, Springer Spaniel, Collie, Dalmatian, German Shepherd, Lhasa Apso, Miniature Schnauzer, Retriever, Shar Pei, Soft-Coated Wheaten Terrier, Dachshund, and West Highland White Terrier
Most common food allergens include: beef, dairy, and wheat.
Least common food allergens are fish and rabbit.
General signs and symptoms of allergies include: dry itchy skin, excessive scratching or licking, bald patches, a high frequency of boiling spots, ear infections, skin infections, diarrhea, and vomiting.
Preventing Food Allergies
Is there anything we, as owners, can do to avoid food allergies from developing?
This is one of the toughest questions in dog nutrition today.
While we still don’t really know how to prevent allergies entirely, there are things you can do that may assist your dog fight off numerous allergies.
When the System Works
The intestinal tract’s ability to prevent the absorption of whole protein is dependant on the health and integrity of the mucosal barrier. It is the proverbial guardian of the body at the gastrointestinal gate.
The mucosal barrier (lining of the gut) is comprised of both structural components and immune system components. The structural components physically prevent the absorption of large proteins. The immune system component is responsible for recognizing potentially harmful contents of the gastrointestinal tract. The health and integrity of the gastrointestinal tract is dependant on the normal structure and function of the enterocytes, effective protein digestion, and the presence of the dog’s immune cells (called IgA cells) in the gastrointestinal tract.
But what exactly is a food allergy?
Food allergies are diverse from food intolerance.
Food intolerance is the result of poor digestion, such as lactose intolerance. People and dogs with lactose intolerance are either missing or own low levels of the milk digesting enzyme lactase.
Food allergies are the over-response of your dog’s immune system to an invading protein. In the case of a food allergy, this protein is contained in your dog’s food. Proteins are present in most of the foods your dog eats. While most people recognize that meats are a source of proteins, there are also proteins present in grains and vegetables.
Any one of these proteins has the potential to cause a food allergy.
Your dog’s gastrointestinal system (mouth, stomach, intestines) protects her from potential allergens each day. Approximately 70 percent of the body’s entire immune system is centered in the gastrointestinal tract.
When your dog eats a meal, the food is first digested in the stomach. The large pieces of food are broken below into smaller pieces by stomach acid and then enzymes and stomach acid work together to break the complicated protein structures below into smaller structures. The partially digested food then moves into the little intestine.
The food is further digested until the proteins are broken below into their smallest parts, amino acids, which can then be absorbed into the body through special cells called enterocytes. Enterocytes act as both a welcoming hostess to amino acids that they love and desire, and as bouncers (door guards) for amino acids they don’t love. When a whole protein is absorbed in the intestines instead of being broken below first, the immune system reacts and your dog shows symptoms of a food allergy.
