So Colby doesn't react, she just moves away or something?

I tend to agree with you. BCs will herd other dogs, which might be part of it, or he wants to play with Colby, but Colby won't respond, so he keeps trying. The only thing I would be worried about is him developing the idea that it's okay to solicit play by jumping on another dog. Kabota loves other dogs and is very tolerant of other dogs, but I think even he would get a bit snappy about that.

That I don't know. Well, kinda, but it depends on if you know somebody like me.

My groomer has a 6 month old standard poodle puppy that likes other dogs but has no dog manners because she wasn't properly socialized (she's only had her a month). So she asked me to bring my dog to the shop for an hour a week so he could teach her to play nicely. I okayed it because I know my groomer and know she knows dogs and trust her, and I know that she was hoping that Kabota would snap and teach her puppy proper manners, but she also knows that Kabota is gentle and wouldn't be likely to savage her puppy.

If you can get a situation like that, it might work. Her puppy is doing much better at properly playing.
