For those of you who have seniors and younger dogs together how do you handle it if the younger dog wants to play with the senior? For right now we just have Saba (10 yo Cattle Dog) and Casja together. Saba is selective about who she plays with and Casja hasn't really been on that list. She doesn't mind hanging out with Casja, but gets very bitchy when she initiates play. This hasn't really been a problem until now because I have always had about 6 rescue dogs here and there was always a selection of playmates.
