I dont know about others but happy cannot be socialized on a leash, or if someone has physical control over her, she flips, she will bark and lung, and start a fight however if she is off leash and controled ONLY by my verbal commands she is very friendly. she just does not feel safe when she is controled, it makes her feel trapped, and and frightend like if something should happen she wont be able to get away. on leash she has gone crazy one week when it mom was handling her(I was not there) she grabbed happys collar instead of letteing happy meet the dog on her own terms, big mistake. happy will be very calm as long as she is not physicly controlled in any way.
