Do not give the dog aspirin - too great of chance of inducing ulcers. Also ibuprofen can cause liver and kidney damage. For an injury potentially this painful the dog should be on torbutrol (doggy narcotic).

I don't understand what your Vet is saying at all. Depending on what "crushed" means the only way a dog heals without surgery is if nothing was broken or really "crushed". Usually when car meets dog, it does require surgery to pin broken bones be it leg or pelvis.

It would seem your options are:

1. Trust the first Vet that essentially nothing was broken, and only bruises incurred. If that's the case then you need to question why the bill is so high.

2. Seek the opinion of another Vet, preferably at a Vet hospital. Yes this means more bills such as Xrays. Better yet have the first Vet send the Xrays to the Vet hospital of your choice for a second opinion. If there are broken bones the chances of successfully avoiding complications goes down hill rather quickly with time. So you need to act now.

You indicate the dog was somehow attacked by 2 pit bulls, but describe no injuries from the attack. Presumably the Vet has given your dog antibiotics?
