To eliminate such bleeding, it is necessary to wrap a solid object in sterile gauze, attach it to the wound and fix it firmly with a bandage. Also, the owner of the dog can apply a tourniquet above the injury site. But it must be remembered that with insufficient pressure, venous bleeding will not stop and can only increase.
