I definitely like the idea of two and am getting another one in a few months so that Jake has a playmate to run around. My hubby didn't want another one, but he agreed to let me get Lily. Unfortunately, she passed away before she was able to play with Jake, and we only had her a very short time.
But, now he's very agreeable to getting another one. I think he saw that having two wasn't that hard, even with the special care that Lily required. He never wanted a yorkie in the first place, but he's crazy about Jake!
