I've never had a vet take one of my pups out of sight. I'm even in the room to help with x-rays as well as if they do injections or stool samples. Like others have said, maybe it's just normal in your area? But I would definitely feel really uncomfortable with them taking them out of the room just to give a shot, I'd never let that happen. Maybe explain this to them and see if they get the picture, or find a new vet. That's really odd to me!
