If your dog has a non-venomous bite, your vet will treat it like a puncture wound or cut.
If your dog has a venomous snake bite, then the treatment becomes much more complicated, and bites on areas like the eye and chest can be more difficult to treat. You may need to go to an emergency vet or veterinary hospital, where they may do some or all of the following:
Administer antivenin (antivenom). To counteract the venom and minimize damage to your dog’s body
Administer intravenous fluids. To promote blood circulation and help to counteract low blood pressure
Treat your dog. With antibiotics, pain medications, and anti-inflammatory medications to prevent infection, keep your dog comfortable, and reduce swelling
