It's a godsend!
I've only had the BarxBuddy for 2 days, and already I've seen a huge difference in my husky/poodle mix, Midnight. She used to pull badly on her leash, not listen, chase after squirrels and pretty much anything that moved, and bark at people and other dogs. But now, she is calmer, doesn't pull, listens to me when I press the button, walks right by other dogs unless they come at us, and this morning she actually left a squirrel alone. I didn't know I could use it on unrestrained dogs, but I'll remember that, because we've had several unrestrained dogs charge at us, and I was terrified my dog and I would get hurt. Midnight growls and protects me, but I will use my BarxBuddy against them also to protect both of us.
