Danville SPCA has a discount coupon, I believe to help with the costs.
Shouldn't be too much price is based on their weight at the time of surgery. However I would definitely go ahead and call to make an appointment. I just made one for my little girl last week and their next available appointment for spay/neuter was the end of October.
I'm not sure but they are very reasonable and will work with you. They help financially whenever they can. I'm far from Rich lol but when I got my dog spayed including all shots, nails clipped, hair around eyes trimmed I spent about $100 to $135 bucks. Just call if you can and they accept walk ins.
