We've lived in the same house for the last 18 years, and we've had up to 5 dogs at a time since then. We've never had a snake bitten dog until this year, when we've had 2! We really think the excessive rain our area has seen this summer has brought the snakes out. Enough already!
The anti-venin treatment is $700. The vet said the reason it's so expensive is that not many people want to "milk" the snakes. Sounds like a lucrative career, but for someone else. I don't care to ever see a snake again.
