We've had puppy play dates with some friends a few time. Tuffy doesn't get along too well with other dogs so I'm always trying to socialize him with others so he'll stop being such a pill. So far he's had playdates with a Bichon (who hated Tuffy), two Boston Terriers (Tuffy was scared of them and they were indifferent to him) and a Chihuahua (who tolerated Tuffy). As soon as Pixie is totally protected with her vaccines I'll be taking her to play with the two Boston Terriers and see if she'll get along with them.
