--Restrain him with a muzzle, even the most easygoing dogs may bite when they are in pain.
--Find a stretcher for the dog, use a door, mat, board or a blanket. If it is a small dog, he may be put inside a sturdy box or wrapped up in a towel or blanket and carried.
--With help, gently lift the dog. When lifting him, one person should be supporting the chest and the other person should support the rear end. Be careful.
--Watch out for fractures. If there is a broken limb, keep it still and supported. Move him as little as you can. If you have first aid experience, a properly applied splint will help reduce further injury. The first priority should be getting your dog to a veterinarian.
