Does she mope around? Does she look depressed? Is she board, is she getting into more trouble now?
I have 3 dogs and they keep each other company especially when we all are away from home. When our first dog was about 11 we got 2 more, Devi seemed so old but she seemed to perk up a bit when Anna and Nali came along. We lost her at 14 and now Anna and Nali are 11 but we still have Kea who's 6 1/2 (going on 1)
