He is maimed, and whines a lot. But he survives! He is hit purposefully by a car, and is carried in a wheelbarrow (alive and conscious) to the village's doctor, who bandages him up. He is seen with slightly bloody bandages and is said to have lost most of his teeth, but you don't see this. Later, the doctor fixes his teeth (with teeth supposedly taken from stray dogs). The dog is shown amid bloody bandages but "smiles" at his owner.
A dog loses most of his teeth in an accident. You don't see it happen or really see the aftermath of it, until a doctor replaces his teeth with mostly-gold ones. There are bloody bandages around but nothing gorey about the teeth themselves.
