I never saw the other thread but from this thread it seems you are having trouble bonding with one of your dogs?

When I got Bubba I got him for my daughter I didn't have "that" feeling like I had with casey, she is definetely the love of my life. Now it has all changed, Casey is still my heart dog but I have gotten very attached to bubba, it took quite a bit of time, but now he is definetely my baby.

Just my two cents
