Trivia: The cover art appears to incorrectly show Max as a "cyborg" dog with a Terminator-like inner skeleton. However, the film explains that he's simply a genetically engineered dog with extra abilities, and thus not robotic in any way.

Trivia: When Max is chasing the cat, the scene was accomplished by training the cat and dog together so they'd be comfortable. The cat was being trained to run towards a toy, while the dog was trained to run towards a trainer making hand signals a short distance away from the cat-toy. If you pay very close attention, there's actually one point in the scene where you can tell that they're running in ever-so-slightly different directions.

Continuity mistake: When Max chases the cat up the tree, in the close-up where you see Max's claws grow, the tree bark texture is different from the shots before and after.
