Fractures
Your animal may be frightened and hurt, so approach with caution.  Use a muzzle and look for bleeding.  Apply a clean cloth or bandage material gently to bleeding areas for protection and mild pressure.  Do not pull on the fractured leg.  Transport your pet as quickly as possible to your veterinarian, using a board or large blanket as a stretcher.  Give careful support to any fractured limbs. Simple support may be better than trying to splint a fractured limb yourself.
