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".
