Ace is somewhat commonly used in greyhounds, albeit in lower dosages. If your vet isn't necessarily greyhound-savvy, that doesn't mean an automatic dump and lawsuit - you can educate him/her for future greyhounds, and work together on future issues. Greyhounds do have special medical considerations, for sure, but it's up to us as owners to stay on top of it, and to work with our vets. I'm sorry your grey had the reaction she did, but I think that wasn't the typical reaction, first of all, and I'd hate to see you lose an otherwise good vet over something like this. We tell our adopters that it's their responsibility to understand that greys are sensitive to particular drugs, because not all vets are going to know the particular requirements of all breeds.
