My dog also avoids people off leash, but on leash she will try to duck away, not out of fear but most people think it's out of fear

she shows alertness but no agression.

she has never shown any agression towards dogs or humans.

she's only alert and starts barking and growling when she doesn't trust sombody. ( but you can still see she is not going full out on this)

I did see however that yesterday she started humping a female samoyed ,Is this dominance or just play ?
