Australian Cattle Dog
About Honey
Honey is a sweet, affectionate girl who loves to spend her day lounging on the couch or bed. If she isn’t underfoot, I’ll always know where to find her. Honey is an easy dog to live with and doesn’t require much to keep her both mentally and physically happy. While she doesn’t typically care for toys or daily frisbee time, Honey loves to go hiking and on truck rides. She is very outgoing, loves other people and is always vigilant for voice commands such as her favorite “place.” AKC Registered | Health Tested (PLL carrier) OFA Hips - Fair OFA BAER - Normal +|+
