Its a predictable (very predictable) sweet, fun movie that'll make any dog lover smile.
Get ready for far too many "dog whines in agreement" moments, but that's small stuff.
Technically if you've ever trained a dog there are a few cringe worthy moments ("sit" and "sit down" are 2 absolutely completely different commands to a dog, dogs are smart, but . . .) its still a real nice G rated heartwarming movie.
