I like the following Old Yeller Homeward Bound 1 and 2. Love Leads the Way Air Bud 1 and 2 (b/c after that things get into that cliche dog saves day by napping crook plot--in a bad way. Then things get even more ridiculous with the Air Buddies series.) Lassie (though some of the dog acting look very dubious in older films) K-9 1-3 Turner and Hooch The Shaggy Dog (1959 and 1976) Eight Below Beethoven 1, 2 101 Dalmations (animated) Lady and the Tramp Balto Honourable mentions Snow Dogs, Benji, Fluke, Far From Home, Look who's talking now (too many? yeah I know. Did I miss anything...?) I haven't seen Marley and Me--i think it'll be too sad and emotionally draining.
