Hi all, i seem to be constantly askin questions at mo. bit of behaviour advice needed. my 6 year old JRT who is an allround well balanced little girl, has this obsession with nose butting my 10 week old pug puppy. i cannot make out if it is play or aggression tho she has not bitten him. she rushes at him and butts him with her nose, she constantly does it when he is running around and knocks him over. poor little boy cannot get more than a few steps without her doing it. what can i do to stop her or should i let her do it. she doesn't intentionally hurt him but obviously she is a lot stronger than him, he doesn't seem to mind. any advice on why she's doing it and what to do about it. thank you.
