What does it cost to get a 4 year old Boston Terrier neutered?? Does he have to have blood work done before? If so how much is that?

Yes the advice above is correct. Sometimes they offer discount specials. So call them and check them out!

Yes, he does have to have blood work done beforehand. (This is to protect him to make sure he's fit for surgery and anesthesia.) It also depends on how much he weighs. To get a specific number, call the clinic and leave his and your information, they'll call back or go to their website and click "Let's Chat". I would rough estimate between 80 and 100 depending on weight and if he's up to date on current vaccines. Either way, it's an excellent price for the same outstanding service that you would receive at a private clinic.
