I guess it just depends on the vet. My vet's office is semi small and the vet, herself, lives right next door. It's not so much as a hospital, a little more personal hands on type of thing I guess. When I went to pick up Nora, all the staff was sad to see her go. She was the perfect patient and so sweet. They all said "you have a sweetie there" Made me feel so proud. lol
Commenting on your dog not having a bowel movement, my vet gives the dogs laxatives so that they don't need to .. well, push? They don't want that area working too much LOL, can you tell I know nothing about medical terms? Your dog may just be having a hard time with it.
