Yeah one time I rode with two trail dogs on a particularly technical 25 mile loop. We rode 25, I bet the dogs ran 60! Twice the owner had to go back and find them after they started chasing after some critter... it was still a hoot and I’ve wanted one since. That was probably 20 years ago and I’ve ridden shorter rides with dogs since. I ride solo 99% of the time it would be nice to have a companion.
