Dog Food Allergies
and Dog Allergy Symptoms

Dog food allergies can lead to a host of dog allergy symptoms which are created from a dog food intolerance. 

And food intolerance symptoms can resemble other allergies, so you will have to look at the whole scope of possibilities.

Dog allergy symptoms can be a very simple way to look for clues as to what is going on with the health of your dog.

However, it may be difficult to tell if your dog is suffering from dog food allergies or some other type of allergy just based on physical signs.

Does your Dog have Itchy Skin?

One of the main dog allergy symptoms is itchy skin and you will have to rule out if it's from a dog food intolerance or from being allergic to say its shampoo.

The symptoms of dog food allergies can come and go.  And dog allergy symptoms can also pop up overnight.

Sometimes, it's because an ingredient in your dog's food has changed or your dog has finally developed food intolerance symptoms to its pet food.

Dog allergy symptoms are sometimes caused by chemicals such as preservatives and pesticides in the food rather than the food itself. 

It is best to avoid all chemicals!


Problems caused by dog food intolerance

Dietary deficiencies are common in dogs with dog food intolerance.

Dog food intolerance that results in diarrhea or vomiting interfere with the amount of time your dog's body has to absorb vitamins and nutrients.

This will cause problems with your dog's skin and coat.  Not too mention that your dog will be suffering from malnutrition as well.

The Elimination Diet and Food Intolerance Symptoms

One way to find the source of dog allergy symptoms or food intolerance symptoms is to try an elimination diet.

This involves removing all of the foods your dog normally eats for a period of time - this allows the dog allergy symptoms to go away.

Then you can start to reintroduce the possible dog food intolerance foods one at a time until previous dog allergy symptoms reappear.

This way you'll really know if your dog is suffering from food intolerance symptoms and from what food source.

Just remember that elimination diets take time and it can take from six to ten weeks for the offending foods to work their way out of your dog’s system.

And when you start reintroducing your dog's original food it can take up to two weeks for dog food allergies to reappear.
