I'm pondering a 24 h hike with my dog. It will be a once in a lifetime experience for both of us. I have little doubts he can walk the distance. He still was all jumpy and excited the evening after a 40 mi / 13h hike that went uphill a lot. (5500ft)

Although I'll cover more distance in the 24 h the profile will be much more relaxed. However the hike would be from noon to noon. So he'd be up and about for well over a day. There will be rests of course but probably not long enough for a nap worth the name.

Does anyone have experience or insights on how a dog handles stuff like that?

Aunty Edith says: guys! Calm down! First of all i can and will cancel big hikes if something is off. I drove three hours to a trailhead once and turned around after 15 minutes of hiking. It happens. Also I have people on call that can pick us up anytime. Secondly: yes dogs will follow you until they drop. But if you can't recognise if your dog is doing badly i really hope you're only commenting and don't actually have a dog.

Hello everyone, hope your having a good day. I'll be going on a backpacking trip in a couple weeks, its going to be rellativly high elevation (around 7000ft) and about 20 miles. While ive taken my pupper on trips of close length (our longest up to this point is 18 miles) however he's never been high altitude. I dont want to risk hurting him or making him sick so I want to know if anyone has had similar experiences or what you would recommend . Any and all advise ia appriciated, thank you. Also in case it matters, hes about 2 years old 60 lbs and a pit terrier.
