I don't know anything about this vet, but will he not work with you on payment? Many vets will treat dogs in urgent need on a payment plan or for a discounted rate. The vet does have some money upfront. Perhaps you could work out some sort of payment schedule for the balance or put part of the bill on a credit card, so the surgery can be done? If not, maybe another vet could be more flexible. Leaving the dog at the facility on IVs seems like it might make the bill larger and prolong the dog's discomfort or pain. You're in a hard spot, and I wish both you and your poor dog the best.
Basenji on Craig's List in SoCal
My mom sent me this listing on Craig's List trying to get the word out in case this basenji girl was bred by a responsible breeder. She has contacted the poster and let them know about Karen Jones and Medfly Rescue.
I hope BRAT can intervene or someone with B experience (or willing to learn) can give her a good forever home. Craigslist can be iffy…she sounds so sweet.
Hopefully someone will keep us updated...
