Absolutely! Jackson is 17lbs and can go all day. He's in better shape than me though LOL... We've never done anything extremely strenuous but he's climbed up steep rocks by himself easily, hills, etc, the farthest we've walked all at once was 7 miles, but I think he could've gone longer.. this was in the winter though, so no hot temps. He doesn't do as well in the heat. The most we do is usually 2-3 miles or so with lots of water breaks but if it's very humid we just don't do walks. Thankfully my dad has a pool so he swims all summer. But yes most any dogs are capable of hiking so long as they are healthy.

PS so jealous of you living in CO! I love it there, my uncle lives there, and I would love to bring Jax one day.
