True to her guardian instincts, she is protective of her family and property. Because she was raised primarily off leash on small farms and mountain hikes, she struggles with leash reactivity toward unfamiliar dogs approaching her or passing by. She would thrive with someone who understands guardian breeds, has space for her to explore, and is willing to work with her on leash training.

She will be great with or without kids around, but any kids just need to be old enough to understand boundaries.

She mostly just wants to hang out and be next to wherever people are at. Rarely jumps up and never tries to play rough with people. In Fenley’s mind, dogs are for playing and people exist for giving out pets and relaxing.

Luna is a playful, curious girl who loves fetch, chase, and tug-of-war, and she especially enjoys exploring the world through sniffing on her walks. She has a moderate-to-high energy level and does best with regular exercise and mental enrichment. Luna is very intelligent, knows basic commands, and is both house-trained and crate-trained.
She’s a dog who enjoys having a “job,” whether that’s training, interactive play, or structured activities that keep her engaged. Once she feels comfortable, Luna is incredibly affectionate and forms strong, loving bonds with her people. She enjoys being close to her person and is okay with most dogs and kids, though she may take a little time to warm up in new situations.

Luna can be sensitive to busy or high-traffic environments and may become reactive when overstimulated, but she continues to improve with guidance and routine. She will do best in a calm, predictable home where she can feel safe and supported.

Her ideal home includes a fenced yard and an experienced, patient owner who can provide structure, engagement, and continued training. She would also benefit from a home where someone is around more often, as she enjoys companionship and regular interaction.

With the right environment, Luna is a loyal, loving companion who will truly shine.
