Given the fact that this is a kid's movie, nothing gets too sinister, however, we learn right off the bat that Dr. Dolittle has been depressed ever since his wife, Lily, disappeared at sea many years ago. While there's nothing graphic, it's clear that Dr. Dolittle has not been taking care of himself for some time, which could lead to a few questions from your brood.
Additionally, the first time we meet Tommy Stubbins is when he accidentally shoots a squirrel named Kevin out of a tree. There's no blood or gore, but we do see Kevin in a whole lot of pain for the first few minutes, which could be upsetting to some kids!
