This tread was helpful because I was wondering the same thing on if I should leave my yorkie and his new sibling in the same bed/pen when I go to work......and at night time I am just going to buy another little cage for the new pup and they will just sleep side by side but in different beds. But as far as work I don't know what I am going to do either put them in the same playpen or what

I would hate to buy another playpen because we really don't have enough rooom for TWO playpens and my husband probably would think I'm crazy

The age difference would be like I have a 8 month old and a 2-3 month old. Any suggestions on what to do when I go to work just put them together or what???
