I don't really know much about posture so I suppose I should read up on that. I feel silly since I know she is just a puppy but I definitely don't want to neglect problematic behavior either. I have learned so much on here but it has certainly made me slightly more neurotic
My pup does that too. He doesn't growl or posture. He's just wanting to play with both at once but can't figure out how (since he won't drop the one in his mouth). IF there was a time when his body language changed, then I would address it, but he doesn't resource guard from me .. ever.
