Wow, only $290 in Sas.? I was quoted around $400 5 years ago and it went up to $600 with added bloodwork, which I would definitely do. To neuter a boy, not spay. Make sure to ask what bloodwork is included or what extra price there is for it.
Some Vets will really pressure you to do the deed too soon and will up their prices after 6 months. Some charge by the weight of the dog but one Vet doubled the price. Something else to ask about.
