My Sonoran Trout Hound goes on all my adventures.
He can smell a rattler a hundred feet away and makes certain to point them out for me since I can no longer hear the bastards. Just last night he let me know I had a diamondback in the horse corral.
He avoids cholla very well and has learned to remove it himself. Rarely has he needed my help plucking it. I think he figured it out as a pup following along on trail rides if he was going to keep up.
Only time I won't bring him is where there's not enough water to mitigate this freaking heat.
He's 1/4 Heeler, 3/4 Mini Aussie so he easily fits into most overhead compartment bins.
