German Shepard Pitt Mix (Elverta)

Meet Lucy! She is incredible sweet and loyal and I hate to have to find her a new home. She is almost 6 years old, spayed, up to date on all shots and flea meds. Overall healthy, except she torn both her cruciate ligaments when she was young so she sits off to the side instead of straight up and down. Her knees don't slow her down though cuz she will still run across the yard full speed to chase critters or bark at the delivery men passing by. She is used to being outdoors in a big yard, but would also love to be an indoor dog. She is pretty mellow, but still likes to get up and run from time to time. She is great with kids of all ages and loves meeting new people. She needs to be an only dog however. Recently she started getting aggressive toward our other dogs with no obvious triggers. It's been slowly getting worse and I don't want things to escalate any further. Please let me know if you have any additional questions or can give this sweet girl a home.
