Yeah my dog.
I live and grew up spending summers and weekends on our family ranch north of Santa Barbara, I was openning a gate and my lab was chaseing lizards as is there pastime. She yelped and went about three feet straight up, my dad and I saw the rattles scoot off into the sage. 30 minutes to the vet, a shot of anti venom and a lab with a head that looked like a Saint Bernard for two weeks. She lived a long happy life after that.
As a kid I was scared to death of snakes, did the research,looked at the numbers 1,200 annual bites average a year in the US resulting in about 12 deaths. I've come realizing that any friday night on the road is way scarier than snakes. I see 3 or 4 rattlers a year around my home and on the trail, I let them see and hear me, I respect their space and we get along just fine.
Hope it helps.
