You have certainly raised some interesting questions and solutions. I have had an increase in my work load, plus I am working on an advanced degree, so I am not home NEARLY as much as I used to be. When I do get home, I tend to "cootchie-coo" the dogs a lot more than I perhaps should. Hey, I am over-"cootchie-cooing" everyone, since I am so often absent . Could it be that they are interpreting this as a slip in my pack status? I or my husband take the dogs for walks twice a day, the big ones separately, then the two Chis. Also, I and my son set aside special play time (hide and seek, fetch, tug-o-war, sit-stand-stay practice, etc.). I will certainly think about your suggestions. I really, really appreciate your help!
