In the backyard, the two dogs were playing tug-of-war as usual when Chief suddenly leaped at his owner’s feet while growling and hissing. Because everything happened so fast, the owner couldn’t understand what was going on.
Chief began to tremble and began throwing a long thin piece of rope around in his mouth. It was also not a tug of war rope.
The dog must be seen by a veterinarian within an hour after the bite. The sooner you can administer anti-venom, the better.
If you live near rattlesnakes, getting your dog immunized against snake poison is a smart move.
