I have a 3-year old Yorkie (Bo) and a 4-month old pup (Kimi) (both females, with the same mother).
The first few days after we brought Kimi home, she really wanted to play... but Bo just didn't want anything to do with her.
Now, it seems they're playing all the time... only, sometimes, I'm not too sure whether they're playing or really fighting. It seems pretty "intense", with all the growling and yipping...!
Is there a way to figure out if they're just having fun or trying to kill each other...
