My dog shakes head, scratches ears, and loses fur. What's wrong?
It sounds like Renz may have an ear infection, and he does need to see a vet for it. Ear infections in dogs can be caused by ear mites, yeast, or bacteria, and the cause needs to be diagnosed so he can be treated. As for the scratching, that can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, he will need a spot on treatment such as Advantage or Revolution. You will need to disinfect the environment as well.
Renz should see a vet today and tomorrow for his ear problems, and possibly the scratching. If he is up to date on his flea treatments, the vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment.
