I have the same problem--a 6 yr old female yorkie that's newly aggressive. I'm new to her (she's my bfs dog), but it's been 4 months now she's lived with us and she still is territorial of him and guards him sometimes. She has been with his ex and kids over the years, and now has come to live with us.
She's been with the 2 of us for 4 months, and still attacks me randomly sometimes when I go get in bed with him (she lays on the floor on his side of the bed) and she'll viciously attack me from under the bed. Or, when he's sitting on the couch and she's laying next to him, she will very aggressively attack me if I go try to give him a kiss or get too close to him. I have no idea what to do because I can't go back and meet her when she was a puppy, and his only explanation is "she's never done this before." But she's known his kids and him and his ex since she was born. I'm new. She loves me 99% of the time except for these completely random acts of aggression..
We've tried disciplining her, not letting her sleep in the bedroom with us, firmly saying no and making sure she knows she's bad--but it's been 4 months now and the aggression is still there randomly when she's guarding him in bed or on the couch.. |
