we look classes at petsmart... and when it came to heeling .. it just wasn't going to work for us.. i think because our pups are so small and at one time or another they have been accidentily kicked or stepped on.. they are a little foot shy... at least Layla is.. so i don't force her to walk next to me because it stresses her out.. she tends to walk ahead.. which i know.. people say makes them think they have the power.. but she loves her walks.. i love the walks.. and this is how she wants to do it
