A couple months ago I had to put my old dog down. When I called the vet to make the appointment the girl asked if I was going to go into the procedure with the dog. When I asked why she said that if I was going to be in the room with my dog they had to start an IV but if I was not going in then they did not. At the time I did not ask why but have been wondering why they would do that based on whether I was in the room or not. Any body know why?
