!!The books

* GermansLoveDavidHasselhoff: Doctor Aybolit, the Russian expy, is very well known, although the best known work about him is an original poem rather than the shortened translations of Lofting's works.
* ValuesDissonance: Although a FriendToAllLivingThings, the Doctor seems to have no trouble with eating sausages, even in front of Gub-Gub the pig. Then again, many real life pigs have no problem eating pork products themselves.
** [[AvertedTrope Averted]] in the 1967 movie. The Doctor is a vegan, hinting in a song sequence that being able to understand the complaints of Gub-Gub and other animals essentially guilt-tripped him into it.

!!The 1967 film

* FridgeBrilliance: Dr. Dolittle's ImprobableFoodBudget is actually explained when he talks about how his animal clients can't pay him with money, but still try to pay him by giving him offerings of their own foodstuff. Dolittle might not eat worms and leaves and the like, but he can keep it and use it to feed his houseguests!
