Almost the same as a spay around here.
Kita was $540 at 2 years old weighing in at just over 80lbs. No pre-op blood work, traditional spay ( not laser) the only extra on her whole procedure was due to her age ( mature spay)
This was an "out patient" spay as well, dropped her off in the early AM picked her up at 4 pm, no meds, no nothing.
This is standard price around here, actually the $540 was the cheapest I found.
And thats why no one around here seems to spay sadly. No hopes in finding a clinic either.
I know a few people who use someones address in Toronto to get it done at clinics (worth the 4 hour drive south) while I somewhat disagree with scamming the system like that, the people who did it were on a fixed income. Atleast they spayed.
Neuters here are $275 +
