“Dog” (*** out of four) was a winning comic melodrama about a former army ranger (Channing Tatum) who is given an assignment to watch an army canine and take her to the military funeral of her owner and they race down the Pacific Coast and attempt to get there on time but along the way develop a strong and special bond with one another. Uneven, with a few unnecessary scenes that could have trimmed film’s length a little, but has enough effective moments to make it worthwhile. Final 20 minutes are particularly heartwarming and moving. Tatum co-directed and him and the dog are first-rate!
