I always tell my vet to use the same procedure they would for a greyhound/sighthound - another CSV breeder told me to do this early on, I don't know how much truth there is to it, but I think it makes my vet pay a little more attention for problems if nothing else. When I did PennHip (required anesthesia), the vet had a really hard time getting my female to go to sleep - both dogs tested had very quick recovery. She recently had a similar problem going to sleep when she had to have emergency surgery to put stitches in a wound. With greyhounds, they have some issues, I think because of little body fat (like many of our dogs, although probably not as much as a greyhound
). There are certain types of medicine the vets will use, and others they will not for greyhounds...not sure of the names though. I have never had any serious problems.
