I have 5 dogs, 1 at a time would be too many walks lol I usually walk 2 at a time, I rarly take my moms dogs for a walk, I always walk Happy and Misty together, Happy walks off leash heeling beside me. Misty does not heel outside, she does not even walk on a loose leash outside, all the trainers that I tried to help are at their wits end, so a haltie is our only choice, she does not heel on that either shestill pulls but she cant pull hard enugh to bother me lol occasionaly I take Blair with me, but not to often, my mom takes care of her dogs exersize. I walked 4 at once before....I will never do that again lol
