Food allergy is the most likely cause of allergic symptoms in animals under 1 year of age.
You may recognize these symptoms: ear inflammation, excessive feet licking, generalized itching, gastritis, and in some cases vomiting and diarrhea. Other clues that your pet may be suffering from food allergies include year-round symptoms and poor response to steroids.

Dog Allergies:
Dermatitis (skin irritation) is the most common symptom for dogs with allergies.
- Intense itching and scratching (pruritis)
- Feet licking and chewing
- Face rubbing
- Hair loss
- Rash, skin abscesses and infection

40% of allergic cats demonstrate similar dermatologic (skin) symptoms as dogs. Cats with allergies will excessively groom themselves, causing hair loss. Some cats may display even more intense irritations such as feline acne, respiratory conditions (asthma, sneezing, nasal discharge, and watery eyes), gastritis, vomiting, and diarrhea.
