I brought Peanut home first when she was 8 weeks, then No body wanted Precious so I took her about not quiet 2 weeks later... its been horrible! They used to play but now its just all out aggression .. but yet they cant be seperated! they sleep together and all that but if u pay attention to Peanut more or even pet her or talk toher .. Precious will shoulder her then attack .. Ive heard male/female in this breed work better then same sex.. wish I knew that then, they had a little brother that lives up the street from me ! I love my girls but they are alot of work !
