Yep, we've had them done. It's harder to watch that it seems to be on the dogs.
Macie just had a cystocentesis done on Tuesday, in fact. No sedation usually needed. It's not particularly painful--usually the dog doesn't react at all. Not even our little wuss Grace so much as whines when she has it done. It's the best way to get a sterile sample and some of our girls are prone to UTIs so we've had the procedure done quite a bit.
