Take the dog to the vet. Don't let it suffer
She is in need of emergency medical help from an emergency vet.

You should have your animal examined by a veterinarian immediately. It is impossible to say what injuries you dog has sustained without examining her. The most common injuries from motor vehicle accidents are broken bones, lung damage, and shock. If you dog has blood in the faeces it suggests there is internal damage.
Yep, Internal Bleeding, It will die if you do not take it to a vet. Immediately
