The last line of the movie is a dog saying "Oh, s*it." Beware of the couple of curse words despite the G rating on the DVD case!
A G-rated version of the film also exists with the profanity edited out. The DVD release of the film is uncut although it retains the G-rating on the back.
A dog calls a lady, "smart ass", and then says, "up your poop, Granny". Later, the dog calls her "an old bat".
