We've got two. We had them from pups, pre our DD (who is now 2.4). As I type she is sitting astride Boydog as he lies in the shade, gently patting his head.
For our family they have been perfect. We got them as puppies and were very aware from the start that we needed to be firm and consistent with them. Neither ever played tugging games, and we've always done exercises where one of us would remove tots or food from them. As a result, both release something in their mouths immediately on command.
They are great with DD. We always knew we'd be having a child, so were careful to be boisterous with them. On the other hand, much as we know they will happily tolerate being cuddled, patted, dressed, and once or twice ridden, DD is always being taught to respect them. They love her, and she loves them, it is lovely to watch. Needless to say though, they are always supervised.
I can't recommend them enough if you are prepared to put the time and effort in. They are fab family pets, and bond well with everyone - although if pressed I would say that Boydog was more my dog.
Am happy to answer any other questions you have. Oh, and there's a picture of them on my profile if you want a look.
