I too was surprised to see the dog. Don't know whose pet he was. Always in the past (at previous camps) pets have been specifically prohibited. I don't see anything on West River's web site about pets, so I don't know what their official policy is. This dog was reasonably well-behaved (though there were a few barking instances), but I would have been happier not to have him there. I guess it was his sniffing around the late-night snack tables that made me uncomfortable...
