my little 12 week old cavalier has developed bald patches along his sides and on one of his back legs. he doesnt seem to be scratching but the vet gave him spot on treatment to treat any mites he may have although she did say that she couldnt see anything moving on him. he does have a bit of dandruff so we have been giving him a little cod liver oil in his food but each day he is losing more and more hair. He is the only pet in the house and has had no contact with any other animals. any advice welcome!
