* [[ReleasedToElsewhere "The long walk."]] The pound isn't just a prison for wayward dogs, it is a concentration camp where they are executed for the crime of being abandoned and becoming a burden upon society.
* The rat.
** Especially the way how, unlike every other animal in the movie, it is never drawn in a cute or at least endearing way. It is instead portrayed with a feral, mad, and just creepy design.
** Even Tramp, in his own way, is quite scary, sporting a very deep growl to intimidate the rat. Very much like [[WesternAnimation/OneHundredAndOneDalmatians Pongo and Perdita's attack on Horace and Jasper,]] or [[WesternAnimation/TheFoxAndTheHound Copper taking on a giant bear]], even though we're rooting for the dog, the film doesn't shy away from how scary dogs can be when they're on the attack.
** Another one when the rat jumps on the baby's crib when its fight with Tramp is almost over. The [[SlasherSmile way it turns to Tramp and smirks evilly]] [[ForTheEvulz leaves no doubt]] about what it truly wanted to do to the [[WouldHurtAChild baby]]...
** Not to mention the fact that Tramp was visibly wounded after the fight, something that didn't even happen when Tramp fought off several vicious dogs twice his size. What kind of monster rat was this!?
** Imagine coming home to your very new baby, and hearing that he'd just been attacked in your absence
* The Siamese cats may be this to young children. That scene where they hungrily toy with the poor fish... ''A Disney Halloween'' even features them when the narrator talks about cats.
* The three frightening and thuggish street dogs (pictured above) who chase Lady in the alley. The way they were portrayed, they looked completely feral, and may have very well torn her apart if Tramp hadn't showed up.
* In one attempt to remove her muzzle, Lady nearly gets decapitated by an alligator. Tramp has [[OhCrap a brief moment or terror]] before he pulls her away from his jaws.
* Aunt Sarah is just downright abusive towards Lady, especially when she has her muzzled. Thank god she was toned down GREATLY in the sequel.
* [[TruthInTelevision Lady being neglected is a very harsh reality for many dogs in real life. It doesn’t help that she’s based on artist Joe Grant’s real-life dog.]]
* Trusty's baying as he and Jock chase down the pound wagon is ''bone-chilling''. If you were a criminal and you heard ''that'' coming after you, you'd probably run for the hills. That, or shit your pants.
