The show revolves around the lives of 8-year-old Arthur Read, an anthropomorphic aardvark, his friends and family, and their daily interactions with each other.
This tv show contains 29 potentially triggering events.
There's an episode where Pal (the Reads' pet dog) gets sick and has to go to the vet's office, and even though they worry about him, he turns out to be okay.
An autistic character named Carl is introduced in Season 13. Although the cool thing is that this show doesn’t usually treat its disabled characters as one-offs meant to just teach the kids about the disability in question, he’s in multiple episodes and for the most part is represented decently well at least IMO. Only issues are the debut episode using puzzle piece imagery and Carl is initially referred to as having Asperger’s but this was before the DSM-V and later episodes update the terminology to “on the spectrum” instead
In "To Eat or Not to Eat", some candy bars are described as addictive. While some kids do experience negative side effects of the bars, they don't get permanently addicted.
there are a couple episodes that can come close enough to be uncomfortable, in one the tough customers pressure Binky to get the cat he is looking after near a vicious dog (he does not do so, and the cat does not come to harm when it ends up nearby, but it can be incredibly uncomfortable to listen to and watch). in another episode nemo infiltrates the tibble home and pretends to be a stuffed animal, the boys briefly discuss "taking out its stuffing" but they decide not to
a cat does not die - however be aware there are a couple episodes with a cat in danger that can cause discomfort, same as the animal abuse comment - in one episode the tough customers pressure Binky to get the cat he is looking after near a vicious dog (he does not do so, and the cat does not come to harm when it ends up nearby, but it can be incredibly uncomfortable to listen to and watch). in another episode nemo infiltrates the tibble home and pretends to be a stuffed animal, the boys briefly discuss "taking out its stuffing" but they decide not to
Two episodes feature a snake named Victoria. There's also the episode "Hide and Snake", which features a snake that's initially thought to be dangerous, but it isn't.
There is a scene where teeth fall out to music in DW Tricks The Tooth Fairy - not damaged, and it is just an imagine spot, but could be unsettling to watch
The series has never had a canonical trans character but at least two major episodes deal with characters preferring to called by their chosen names being S2E19A DW’s Name Game and S15E7B What's in a Name?
Some episodes are health-related, and as a result there are various episodes that have scenes in medical facilities. There's nothing too scary/graphic, and these places are generally treated as good things.
The episode April 9th involves the aftermath of a fire at the school and it demonstrates the characters having symptoms of trauma such as Arthur excessively worrying something bad would happen to his father and Binky seeing smoke in the hallways
The segment “Bleep” is all about teaching little kids that they shouldn’t swear. And as the title implies the swearing itself is censored, to the point where as an adult it’s hard to even figure out what they’re supposed to be saying a lot of the time
There are multiple episodes dedicated to educating kids about Jewish culture via Francine. Even in-universe the worse that happens is sometimes a character (mainly Muffy) commits a microaggression such as not understanding why she wasn't at Muffy's party when Francine was celebrating Hanukkah and those are resolved rather quickly.
Not in the usual transphobic sense but I guess still relevant: George imagines himself on a planet with customs unlike what he is used to, and this involves imagining Arthur wearing a tutu among other mismatched clothes.
Oddly enough there’s numerous episodes dedicated to teaching against cultural stereotypes such as Dear Aldi and In My Africa. The show itself is pretty well known for having legitimately good diversity for the most part
Obviously no because it’s a kids show! Although there is one episode in which they think Mr. Ratburn is marrying a woman only to have the reveal that said woman is his sister. It’s only a misunderstanding and the kids are more just relieved that the wedding is going on no sweat
The show hasn't ended yet, so we don't know for sure. The episodes "Nerves of Steal", "Rhyme for Your Life", "The Pageant Pickle", "Just the Ticket", and "Binky Can't Always Get What He Wants" end on somewhat sad notes, but it should be noted that the endings aren't terribly upsetting and everything is back to normal by the next episode.
