I haven't done the vet shops, infrequent as they are. I prefer vets of choice for my critters. Some vets are about more than the bottom line. I do business with competent and caring doctors, who are sympathetic to 'owners' of rescue animals. I have found local agencies might lend assistance, financial or adoption, such as animal shelters, groomers, or boarders.
A month ago, I stepped out on the back porch with my morning coffee, and heard a meowing kitten. Somehow, someway, there was a helpless, barely weaned kitten. Probably, her feral mother dropped her. I tried to find her a home, but with no luck. I even offered the local shelter $40 to take her. Still no luck. Her name is June Bug. She'll soon get fixed and become part of a household that certainly did not need another cat.
Anonymous Girl, good luck with the dog. A shoestring? Poor thing. Lucky to have found you.
