I have a dog & cat suffering from itching and hair loss on their hind quarters./Is this some type of mites?/We thought it was fleas at first, but we can't find fleas on the animals./Any ideas, looks like a red sore rash on the dog, but the cat is just loosing his hair./We have looked for anything on the animals, but we can't see a thing.
It is possible that this is a mite. Allergy, flea bite allergy and skin infection are other possibilities. I would have your pet checked by the vet. vetcare
