Our small lap dog, is alway's scratching constantly, we've bought her a shampoo that swears it'll stop the scratching's and also we've bought a spray for the scratching's but no flea's or other skin problems that we can see, what is causing her to scratching so much !!
Your pet needs to be seen by a veterinarian. There are many causes for scratching including allergies, mange, fleas, skin infections etc.. The treatment depends on the cause. I would not wait long for a vet visit b/c dogs can damage their skin easily. Vetcare
