To answer your question Xena will be a year old in 5 days. The Husky is actually 3-4 months younger than Xena and only an inch shorter and sometimes stands up to her when she's resource guarding. If she's in her crate and he's not, he dances around it and gets her riled up. When he's in his crate and she is out, she walks up to the crate submissively with her tail wagging and ears down. I've even seen her try to clean his teeth. But when it comes to resource guarding she acts very dominant toward both dogs (never us). We are the pack leaders, but honestly not sure who is next in line, Xena or Thor (Husky) lol. Maybe they're equals or something. Anyway thanks for the explanation.
