Continuity mistake: When Hubble is addressing the other dogs in a garage, on the day Owen can understand dogs, he is standing on a wooden crate. In some shots, there is a noticeable gap between the first and second piece of wood from the front on the crate. In shots from between Hubble, the gap has moved to be between the second and third piece. (00:20:15)
Continuity mistake: When Barbara Anne's owner comes to the door to talk to Owen, she is holding a coffee mug by the handle. The next shot shows her holding the mug on the other (non-handle) side. (00:05:50)
Continuity mistake: When the boy and his family are at the pound looking at Hubble, the man at the pound has a sandwich in his hand. The size of this sandwich changes significantly between shots. (00:11:05)
