I had the same reservations about getting another dog-especially another male, but two months in , I wouldn't have it any other way! Neo was an "only child" and DH and I probably projected a lot of our fears (or neurosis, lol) on him. Since we got Connor it seems that everyone is much more relaxed. We give each boy his own one-on-one time, and when Connor works an nerve on Neo, he just finds his "hidie hole" for some alone time. These little boys are bonded and quite happy!
