Super that you have a adopted a mill rescue. We've had our little mill rescue for two years already. We also haveour female who is 11yrs. and our little boy who is 7yrs. We took them with us to pick up our little guy so it was neutral ground. Once home it took time but I made sure that all three received the same amount of attention. Also once the pecking order is straightend out and your chip doesn't feel like he's not top dog anymore things should come around. But it does take time, but certainly worth it. I applaud you for adopting a mill dog and hope he's in his furever home. Best of luck.
