I've walked 2 dogs at once. Didn't have any problems. I was training a neighbours dog with my dog. The neighbours dog loved my dog, so she did everythig my dog did & tried to do it better. it was great walking them.

However I was yelled at wheni got home. What if they went nuts & pulled.. I was like &?? My dog is very well trained & doesn't chase anything. The dog in training only weighed 50 pounds if that, so if she freaked out I could just pick her up.. Like I did when she was nearlly attacked by 2 loose GSD's.

I've trained 200p Rotties to heel. I think I can manage a 50p sweet non pulling short haired Collie type mutt

When I walked my own dog, I didn't walk him. he walked himself.. I made a mini leash. it was about 6 inches long & he would pick it up in his mouth & walk ahead of me.
