A couple years ago, a friend of mine had her dog down south for training with a pro. The dog jumped in a pond right on top of a water moccasin which bit her hind leg. Saw a vet immediately down south and brought her back home to heal. The damage was so severe, tho, her leg at hip had to be amputated. Wasn't sure if she'd ever want to get into the water again ... but she did and just achieved her MH title.
