I know that sounds like such a parent thing to say!
But I was wondering - is that a possibility? Do they learn bad behaviors from older dogs? Or do you find in puppy classes there are some pups you just kind of steer yours away from? (And hope your puppy isn't that one pup for other owners?
We don't know many people with dogs, but I'm hoping to avoid "play dates" with one dog in particular. He's a nice dog but exhibits some key "bad" behaviors I specifically plan to either try to avoid (train puppy that the RIGHT thing to do is the exact opposite) or would be curbing fast if she picked them up. I don't plan to even let them meet until she's older and I've laid a good foundation with training.
Or am I thinking about this but it's actually nothing?
