Good choice, Dolly Sods.

I have a 125 pound chocolate lab named Tater that loves being on the trail. As someone else noted, concrete and asphalt are the best for nail maintainence, a daily walk keeps them trimmed down. I have a bell on my walking stick and I hang one on Tater so we both know where we're at. At the end of the day Tater is tired enough that he just goes inside the tent and crashes. A few times I've left him outside, wildlife would get him on the chase then I'd lay awake worrying about him getting lost. Tie him up outside the tent and he just barks all night. In the tent he just sleeps. His nails have never damaged the tent. Water dogs with webed toes will bring in plenty of mud so I bring a small wisk broom to sweep out in the morning. Out in the wild he does take on a new aroma that can get intense in the tent. I do not take Tater on long trips of more than a couple days even though he's good company.
