Continuity mistake: Right at the start of the movie, the dogs go though the bank's front door, which can only be opened from the outside, which means someone had to have opened the door for the dogs.
Continuity mistake: You can see by the first 2 dogs going out of the bank that there are 2 cars that are white. Then the last dog goes out and you can see the reflection in the window, and the 2 white cars have turned into 1 red car.
