If you’ve noticed your pet has been scratching, licking, chewing and/or biting more often than usual, you’ll want to take a serious look over of their skin and coat. Of course you’ll be looking for evidence of fleas, usually the first thing that comes to mind. However, a symptom of an underlying health problem is pet skin allergies. On the surface of the skin you will find red, irritated and/or dry patches of skin, as well as possible areas of hair loss or even open sores (depending on how long your pet has been itching or chewing the area).
The most common pet skin allergies are from parasites, such as flea saliva (not necessarily a major flea infestation as just one flea bite can cause an allergic reaction in some animals), an allergic reaction to a food, ingredient or by-product, or a hypersensitivity to pollen, wool, dust mites or other inhalant or contact allergens.
