Never underestimate a little dog. Once I saw a small poodle following its master up the trail to Cucamonga Peak in the Cucamonga Wilderness of the Angeles National Forest. The trail was rocky and steep, and we were about two miles up it, but there was the little guy keeping up with his owner who was moving at a steady clip. The only problem that I had was that the dog shouldn’t have been in a federal wilderness area (we had stopped with our Boston Terrier at the boundary). Like many dog owners, his master presumed that his dog was well behaved enough that he could snub the rule.
