Mild allergic reactions

Mild allergic reactions

Like humans, cats and dogs can suffer from allergies as well that may be more pronounced depending on the season, weather or diet. Food allergy is one of the five most common allergies known to affect dogs.


In a pet with an allergy, the immune system overreacts and produces antibodies to substances that it would normally tolerate. This excessive response is termed an allergic or hypersensitivity reaction.


Signs your dog might be allergic

In dogs, signs of food allergy are usually itchy skin or digestive disturbances such as vomiting or diarrhea. Other more subtle changes can also occur, including hyperactivity, weight loss, lack of energy and even aggression. The most common clinical signs of anaphylaxis include itching, red skin swellings called wheals or hives, a swollen face or muzzle, excessive salivation or drooling, vomiting, and diarrhea. In systemic anaphylaxis, the dog will have difficulty breathing and may be cyanotic (have a bluish color to the tongue and gums).


Signs your cat might be allergic

The most common sign is itching of the skin, either localized in one area or a generalized reaction all over the cat's body. Another manifestation involves the respiratory system and may result in coughing, sneezing, and wheezing. Sometimes, there may be an associated nasal or ocular (eye) discharge. The third manifestation involves the digestive system, resulting in vomiting, flatulence or diarrhea.
