Hmmmm... it goes both ways. We haven't had a new dog for 10 years, and these dogs were outside--lived in the barn--for the first 3/4 of their lives. It was when Shimano started being terrified of lightning that they weaseled their way in. :wink: Now she's in all the time. If a dog comes near this place she goes nuts--never wants to play with another dog, but we haven't tried having one over since Suzy's been gone. It'd be a good idea to go a practice round. My son's fiancé has a dog that could come for a visit.
