Do Shelties do well with other dogs?

Yes!  There are several statements about Shelties being "Better In Bunches" or "Like Potato Chips - You Can't Have Just One".  Each Sheltie, of course, has their own attitudes and personalities, but the majority of them do well with other Shelties, or other breeds.  Many say, though, it is best to have both genders and not just males (or just females).  We, however, have been very lucky with very very few "tiffs" and never any serious aggression, despite owning both genders in the same household.
