Description: Bob Tucker's parents start to think he's crazy because he seems to talk to his dog Wolf (Unknown to them, he really is talking to him with the ESP pills, plus, he got Wolf centuries past with the time machine). The boys consider keeping him in Kai's future, but Kai's people want to defang him! In the end, they lease him out to movies, because Wolf has become a fan of Lassie movies and decides he wants to do that. Dion does not appear in this story. I was trying to remember if I read this one as a kid. It seems kind of familiar, but maybe not.
