Show Dogs

During the first scene at the dog show the chihuahua Chloe and her mate Papi from the movie Beverly Hills Chihuahua get a short cameo, with Chloe (noticible by the same voice from the movie and same diamond necklace) having a quick line about talking dog movies not being mainstream anymore.

Just as Frank is about to be struck by the propeller of the Piper Chieftain Max is taxiing in the hangar, Mattie pulls a red handle on the cockpit floor, stopping the aircraft. What Mattie is pulling up is not a brake handle, but is in reality the handle for the emergency gear extension hydraulic pump and is not part of the aircraft's brake system at all.

Credits contain supposed "bloopers", many of which involve computer-generated characters messing up.

Two scenes were cut upon the second week of its US theatrical release - these edits also apply to the home release. After receiving complaints, presenter/distributor, Global Road Entertainment deemed them inappropriate for children. They concerned the subplot of Max having to have his testicles touched by the show judges. However, all UK (and therefore Irish) releases are uncut with the same PG rating - according to the BBFC, this is because the controversial scenes are "entirely innocent, non-sexual and occur within the clear context of preparation for and judging in a dog show".
