I got my female yorkie on Friday and I went back to the owner and got her brother today, Tuesday. We brought her brother in and the female won't STOP picking on him. She won't let him eat, sleep or drink. Is this normal? He doesn't seem to play with her back he's actually trying to dodge her. I'm a new yorkie owner and want to make sure I'm not freaking out. Do they know their related? It's only been a few days away from each other.
