Cats, dogs, and other animals may have warning signs that they have skin problems. They may have fur loss on parts of their coat, or it could become dry and brittle. They may be unusually sensitive to being handled in certain areas. Dandruff and other visible signs of skin flakiness may occur. When you brush your pet’s fur, there may be chunks of fur coming out onto the brush or otherwise showing signs of ill health. Rashes, raised lesions, and other red and irritated areas could also indicate a problem. One common symptom is that the cat or dog is scratching and grooming themselves more than normal. In severe examples, they could scratch hard enough to break the skin.
