Yeah,Luna gets a little nervous at the vet, at first, but I always make sure to take her favorite toy and some treats so that she gets use to going. She even gets playful on the counter/bed where they put her. You can see her little tail wagging and all... I think it's only a matter of time and making it a positive experience for your doggies. You should be careful with the anal glands because I heard its more of an issue in small dogs, like our yorkies(which is why I posted here). Try to get your yorkies accustomed to going with treats and stuff... just a suggestion
