My 13 week-old cockapoo puppy already hates being brushed. I tried a slicker brush very gently when we first got him at 8 weeks and he was terrified. I managed to get it through a few times while I fed him some boiled chicken. It was suggested to try a soft boar bristle brush to see if the softer bristles would cause less anxiety but he freaked out yesterday. Now I am worried b/c he is a breed that definitely will need to be groomed every 6 weeks or so and I am terrified I will have a dog that no one will groom b/c he is so scared. Ideas?
