I actually have never really had a problem controlling, Sassy. She has never had an interest in other people unless they were guest in her territory or people who came up to her. She is EXTREMELY scared of bigger dogs, so never goes up to them either. Smaller dogs she can be as friendly as possible depending on the dog. If the dog is friendly to her, she's friendly to it. I will never understand why people take their dogs out who aren't trained properly and can't be controlled. Honestly, though I see why some people would bring smaller dogs out that are a little hyper since they can be contained easily, but they shouldn't let them off the leash. That is just plain irresponsible.

My dog is fine off leash. She walks right next to me in a perfect heel, although she wasn't taught "heel". She just does it. She has no interest in people or other dogs, or running away.
