Well, Josefina always got along with other dogs then suddenly, one day she decided she wasnt going to put up with other females anymore, so dogs CAN surprise you, they might now be tigers, but they arent machines, either.
I mean Charlie is not strong enough for me, and i always wrapped rope around my hand ( its better to pull out my muscles than my daughter). Charlie when spotted something always gives a body signal ( head up, his tail looks like car antenna)so when i sees that, i'm ready for it
