Besides ectoparasites, an owner or groomer should look for other skin problems. Owners frequently complain about the scratching dog that kept them up all night. Dogs that itch excessively need to see a veterinarian for a cortisone injection or other medication. Alopecia in certain areas from poor hair growth or hair loss has many causes. Mange, allergic dermatitis, ringworm, and bacterial dermatitis, can all appear as hair loss.
Many skin tumors can hide and only be found during grooming and bathing.
When found early, many can be easily removed by your veterinarian. During your dogs bath and groom, look closely at the coat and skin for these problems. For most skin conditions, bathing and grooming is beneficial for your dog. Consult with your veterinarian for the shampoos and conditioners that would most benefit your dog's coat and skin. Your pet's skin is quite different from human skin.
