We were just camping & had both dogs with us. True, it did say dogs were to be on leash but John thought it would be OK not too. We were not looking one day & Candie started after a lady & her pomeradian(sp). Candie wouldn't hurt but could knock you over and want to play (she weighs 103 lbs.) then John called her & she came back. Anyway, the camp cop came to tell us to put both on a leash (Minnie only uses 3 legs & stays by the pop-up or inside just laying). John got upset & since Candie is really our DD's dog & he took her home that night & Minnie too
