How do you immunize dog from snake bites?
There is a rattlesnake vaccine available for dogs. It was
approved by the USDA in 2004. The initial vaccine should be given
in at least two doses about 30 days apart.
The vaccine has been reported to both delay the effects and
reduce the severity of rattlesnake bites and help dogs survive and
recover more quickly with less pain and swelling. It is always
recommended that a rattlesnake bite be treated as a veterinary
emergency-even in a vaccinated dog.
Once vaccinated for rattlesnake bites, the dog would need yearly
booster shots.
The above is spot on. It will also provide some protection from
closely related rattlesnake cousins. It does not provide protection
against Water Moccasin (Cottonmouth), Mojave Rattlesnake or Coral
Snake, if memory serves.
If you can, ID the snake; it is a veterinary emergency, and
anti-venoms are available if you know the type that bit your dog.
Get to your Vet ASAP.
