Is there any way of clearing them without the rubber glove treatment? My dog smells a bit fishy and I'm thinking it may be his anal glands, last time he had them seen too ( as a pup ) he exploded in my car on the way home so I'm not keen on taking him ( as I have a nice new car ), is there something I can feed him that will help clear them or do i really need to take him to the vets?
