Dog Food Allergies – Symptoms and Treatment

While on the course, the defensive antibodies within the host body will attack the invading particle, and this immune mechanism will make your dog to become sick. Nearly, 10 percent of dogs are suffering from food allergy at some point. Moreover, they are difficult to identify first, but once, it has identified, it would be very easy to treat.

Difference between Food Allergies and Food Intolerances in Dogs

Usually, dogs might get vomit or suffer from diarrhea for a while, at the moment they ate food that is allergic, such as dairy products. And many pets have suffered with food intolerance, which means, a kind of heartburn or indigestion immediately after eating a spicy food, just as experienced by humans. Since, this condition can be uncomfortable, hence, it is better for a dog to stay away from these kinds of foods that causing allergies and as well as the one which is intolerant to their digestive system.

If dogs might have happened to eat a food, which can cause allergic to them, then they will undergo some common symptoms such as rashes on their skin. Sometimes, if a dog has prone to be allergic, then most probably they had been inherited with a certain kind of genetic pre-disposition to acquire those allergies.

Difference between Cause and Triggers

Usually, many pet parents have said that eggs can cause allergies in their pet, but, actually eggs are the triggers. But the most common reasons for allergies in dogs are inheriting allergies and environmental allergies. Meanwhile, given antibiotics at the younger age of dogs can even be one of the main causes of food allergy, because, in this case, those antibiotics might have destroyed the bacterial flora in the digestive organs, which is consider as the largest immune system of the body.

Some of the most common food allergy triggers in dogs are

  • Beef.
  • Lamb.
  • Dairy products.
  • Chicken.
  • Corn.
  • Wheat.
  • Fish.
  • Chicken eggs.
  • Soy.

Hence, to avoid these conditions such as intolerance or an allergy, then dogs are need to be offered with rice along with some other favourable foods. Moreover, make use of the availability of hypoallergenic dog foods, which doesn’t include these allergy triggers.

In order to analyse whether the allergy is caused by a food or atopy or flea bites or intestinal parasites sensitivity, then the dog should be engaged in a food trail. Typically, this trail will last up to 12 weeks, where the dogs are been offered with variety of protein and carbohydrate foods that they never had before, which is called as novel diet. So, you can easily figure out the combinations, which have been found to be hypoallergenic for dogs.

During a food trail, your dog is not given with anything other than the trail food. This also includes no treats, no flavoured medication, and no chewable toys. Despite everything, it is advisable, while on a dog food trial, the dog should be kept out of the room during mealtime. Because, even eating a small scrap that falls out of the table can be more enough to spoil the food trial and thus will make the results to go useless.

After the 12 weeks of the food trial, the dog will be offered with regular diet. Perhaps, again if you look for any of the symptoms of a food allergy, now making the proper diagnosis would have been easier.
