I admit, I don't brush Hunter as much as I should. He has never had a mat though. He is medium haired, and I have a zoom groom, metal bristle brush, and a nylon bristle brush. Anyway, I give him the nylon brush to bite while I zoom groom him. Its not his favorite thing. So today I brushed him, and he was all smooth and nice looking. He gets up and he looks all scruffy again. I mean he looks like he is a stray. He'll be walking and it looks like his fur is in small clumps along his body. However, I touch it and its smooth. I read that it could be some sort of illness? He has no fleas, He doesn't go outside, and my dog is always treated with Frontline protection. Hunter grooms himself normally and there is no fur falling out. It's just on his sides. His front legs are fine (he has short hair on his legs) Back legs, not really a problem, head is fine. Tail is long haired and always looks poofy. Maybe its because he is still growing? Hunter will be 8 months old next week.
What can I do to make him look smooth?
