My dog Bear has always been my favorite herping partner. She always finds the snakes/frogs/whatever but never actually chases or attacks them. In fact, she's so helpful that I've pretty much given up herping when I can't take her with me (I find no snakes, so it just ends up being hiking).
Well, on a recent trip we were on one of our favorite paths down near the creek when she started acting funny and circling a wide area along our general path and trying to discourage me from walking there as well.
Turns out that what she was trying to avoid was a nest of newly hatched baby copperheads. Normally I wouldn't say that this was a lifesaving thing, as most of the time the copperheads would just run when we got to close, but the babies were very newly hatched and there were about seven of them in the same area basking, and very well camouflaged; in other words, it would not have been a good idea to walk over them!

Silly little story, but I felt like sharing it
