Bingo (1991)

When circus dog Bingo runs away from the Big Top, he saves the life of Chuckie, a young boy who is having trouble fitting in. The two quickly become best friends--skateboarding, playing pinball, and doing math homework together. But Chuckie's parents discover the stowaway pooch and make no bones about the fact that Bingo will not accompany them on their cross-country move. What follows is a heart-warming 1000-mile adventure of puppy love and loyalty as Bingo and Chuckie encounter nutty characters and hilarious situations in their quest to be reunited. Dog catchers, kidnappers, hospitals, and not even prison can keep these two apart.
