Parents need to know that Mickey Mouse only appears in half the cartoons. Most feature Pluto chasing another creature, getting himself in a "situation" with him either falling or smashing into something or having his bottom bit by the other creature.
Positive messages:Mickey and Pluto have an unconditional relationship as best friends.
Violence & scariness:Pluto falls down and sees birdies but he always gets back up.
Ok, not that violent, but a lot of the scenes are reminescent of Tom & Jerry. Just old fashioned bite the other animals tail or womp him over the head type stuff. Was enough to make my 3-year old look pretty worried at times. There were probably twenty instances where some animal got Pluto's goat and he tried to take a bite out of it and missed. I'd probably say wait until four years if you bother with this one at all.
