I'm something of an expert on dogs' opinion of caching since I am one. I'm not very fond of caches where I just get out of the car and then get back in. The ones I like best are where i get to walk along a nice trail with a few stops along the way. My person almost always remembers to bring water. And dog treats. Once I even found a dog treat in a cache. I think maybe my person put it there but I didn't see her do it. I'm a Mellow Sheltie so when my person is exploring places with lots of Sheltie size brush I take a nap. Also sometimes when there are lots of caches along a nice trail we skip some. That way we can come back again. Also when my person is walking in circles, she lets me guard the backpack so I don't get dizzy. Anyway I'd always rather go places with my person then stay home and sometimes I find the cache first.
Oh I forgot to say I'm a travel bug. I like to go to events and get discovered but I never get left in a cache. I even have business cards with my number on them.
