Kingsleys Vet Bills

My dog, Kingsley needs surgery and an ultrasound. We've already paid 1500 for xrays and medications and I can't afford his ultrasound or surgery. I wouldn't ask if I had any other way. Kingsley has been with me since he was 6 weeks old. He is an absolutely amazing dog. He's been there for me when I had no one else. I want to do what's right for him. I'll appreciate any help you can give, more than you could ever imagine. Thank you.
