Like people, dogs can have allergies to certain foods.
A food allergy should not be confused with food intolerance, however.
Typically, food intolerances lead to gastric symptoms, while food allergies mostly manifest through skin symptoms.
What are the most common food allergens for dogs?
According toVCA Animal Hospitals, the most common substances to cause food allergies in dogs are proteins.
Additionally, cutting out all of these foods will likely result in your dog experiencing nutritional deficiencies.
To avoid this problem, your dog will need to be tested under the guidance of a vet.
To avoid interfering with the results, no other food may be given during the diet.
According toPetMD, there are also over-the-counter tests you could conduct, but these are less accurate.
