Sadie's Tail

I really wish Sadie wasn't so picky about the dogs with whom she will play.

This past weekend I spent two days helping a friend do some home design. I had to leave Sadie behind, even though my friend has an awesome, huge backyard - because she has a dog in that awesome huge backyard.

It truly bums me out that my dog can't socialize with others.

Anyone have any ideas on how to fix this problem (without losing a friend, their dog, or both)?
