Why do so many purebred dogs seem to need to have their anal glands expressed regularly?
I have a few friends with smaller purebred dogs. They have to take their dog into to vets to have the anal glands expressed regularly. I had never heard of this before.
Is it fairly new?
Does it have to do with the size of the dog?
Does breeding have anything to do with this?
