The punching in the face is the only thing I wouldn't have done with my own dogs. I've seen other people do it in play before, and honestly, I don't like it. HOWEVER, the only reason I wouldn't do that with my dogs is because if someone ever hauls back to punch them, I don't want them to have a play reaction to it. I want them to have a real "WTF are you doing?!" reaction to it. *I* will never punch them, but if some idiot thinks he can come into my house and punch Simi in the face, he's got something coming, and quite frankly, he deserves it.
The "kicking" was nothing. I do worse in play with Crash on a daily basis. I will be tugging with Crash and "Kick" him and put my foot under his belly and pick him up a little. He loves it.
I smack my dogs around in play, though. I'll admit to it. I know that from far, people think I'm probably beating them a lot harder than I am, but I will give Simi or Crash a solid smack on the side when tugging/playing rough.
Honestly, that dog looked like what it would look like if someone else tried to play with Crash like I do. Even now with Crash, if I get "scared" of him while we're rough housing, he'll follow me if I run away/back and jump on me. Much like that dog was doing, but Crash knows that at any time I'll say enough and that's it, and so he doesn't ever give it that much oomph.
Yeah, honestly, I wouldn't even call most of that teasing.. I'd do that with my dogs and they'd love it. All but the punch. But that's just personal preference, I guess. I do know a guy locally who will punch his dogs in play like that, and it's all fun and games to the dogs. They love it.
HOWEVER, if that isn't his dog (and it isn't, right?) I don't think he should have been doing any of that... but I pray to god people never get video of me playing with my dogs!
