I hope the little pup gets help but it can get expensive. A JRT was brought into my brothers vet clinic after it had been hit by a car. I said I would pay for his care while they looked for the owner or found him a new home. They figured it would be about $200. After more ex rays the vets decided it was a broken pelvis and he needed a vet specialist, I had gotten to know what a sweet dog he was, in spite of his pain, and again I agreed to pay. The bill came in at $1500. which I paid. I am not sure I would have done it if I had known ahead of time how much the bill was going to be. I don't mind giving $1500. to a deserving charity but....... to one stray dog?
I wasn't going to back out on my word. The end of the story is the dog healed, walked with a limp, found a great new home and doesn't chase cars anymore. I got a very nice thank you letter from the new owners.
