I just wouldn't have believed this unless I had seen it. And I did see it, and my camera just happened to be available. Greyhounds are NOT golden retrievers, they do NOT cuddle with each other, in fact, most of them need a 'buffer' space to sleep comfortably. I'm very happy to know that my dogs can be the exception to the rule. With 4 sighthounds (okay, technically, Q is a toy breed, so really 3.25 sighthounds), it makes me a very firm believer in behavior molding and the ability to influence the way they interact together as a pack with a little diligence, persistence and guidance. Space issues, snipping and grumbling are not tolerated, so it can't just be luck (although they are all really really even, good tempered dogs).
