There is lady down my street who walks her 3 dogs all at once & her Pittbull, i think it is too much, she is clearly being pulled down the street, i walk one at a time, both mine weigh more than i do so it would not be wise to take 2 of them at once, plus it could be dangerous, if i had smaller dogs i would walk more than one, but with mine i have to be responisble with one at a time, i can control each one better, and then i get one on one time with them too, which we all enjoy.
