She's 3. She's fairly new to us, so I've not let her off lead in many places, nor with many other dogs around. But she's been off lead a few times with a friend's dog or a dog whose owner did not seem to mind. My dog is very vocal when she plays, play-growling, but she jumps up at the other dogs and rams them and mouths them. The other dog kept play bowing at my dog, so I assume wanted to keep playing in this way, but it looks very rough to me and I'd be afraid of her playing in this way with a smaller dog.
What do I do? I'm apprehensive to let her off lead with other dogs around? Is there a way to train her to dampen down her playing style?
