Areas of the Body Where Dermatitis Can Affect Dogs
Dermatitis in dogs is inflammation of the skin and can be caused by food allergies, environmental allergies and external parasites, as well as bacterial and fungal infections.
Signs of dermatitis can arise anywhere on the body, however, some areas are more likely to be affected than others. Read on to learn where dermatitis can affect dogs on their body.
How Do Dermatitis Issues in Dogs Arise?
Food
Food allergies can cause dermatitis when harmless ingredients, typically a protein, found in food are mistaken as harmful molecules. As a result, the body will send out an inflammatory response which leads to an allergic reaction.
Environment
An allergic reaction is triggered by a dog's immune system when a particular element, found both indoors and outdoors, breaks through its skin barrier. The result is often inflamed, irritated and itchy skin.
External parasites
External parasites can be found in a dog's environment on both objects and other pets. Once parasites have infested a dog they will likely result in signs of irritation and can even lead to an allergic reaction in some cases.
