Hi, I am vetmom and am happy to answer any question about your dog's veterinary issues.
I just had a similar surgery performed on my dog and is was over $300 with my veterinary discount.So it would have been about $600 but a small tumor was removed from the other eye. Laser was used and the dog's eyes have done beautifully. Eye surgery is technically more difficult.
No wonder folks can't afford veterinarians anymore! Maybe you could get a second quote from another veterinarian? I'm in Southeast US where costs are generally lower. Your price quoted does sound a little high but just my opinion. Don't know the cost of real estate, licenses, etc in your area.
Kind regards, vetmom
