Though the dogs fate is left unknown at the end of Season 4 episode 1 it is quickly revealed in Season 4 episode 2 that the dog is fine and with his owner.

S3:E10 Claire wakes up to find ants all over her legs.

a boar dies pretty graphically

In season one, there are scenes of Highlanders carrying dead game animals, such as rabbits, that they intend to cook. Season three has a shot of a skinned elk carcass being butchered.

S04E04, 28 minutes: A horse gets pawed by bear but survives.

There’s a big 🐍 snake passing through Claire when she get to the island, after she threw out the ship.

Jamie (Claire's second husband) beats Claire in season one as punishment after she ran away and inadvertently got kidnapped. He later apologizes when he learns why she fled.

There is physical abuse of a child in season 1 as well the rape of a child later in the series

Claire grows dependent on ether in season 6 as a way of dealing with her trauma from rape. Fergus abuses alcohol in season 6.

In 6x01 Claire uses ether on herself as a form of self medication to deal with the trauma of her rape in season 5.

It's heavily implied Fergus has turned to alchohol as a coping mechanism in 6x01-6x03

There are long, graphic torture scenes in season one

In 5x01 Jamie helps Roger to shave his face before his wedding, it’s mostly there to be comedic

A preacher gets burned alive and his lover joins him

Not cannibalism but in season 3 there’s a freak episode that involves human blood

A man has his mangled arm graphically amputated in season one. A kid's hand is chopped off on screen in season three.

major finger/hand mutilation accompanied by rape in season one finale

Roger is hanged in 5x07 in a series of flashbacks, and is fairly traumatized by it. His broken voice does cause problems for him for a couple of episodes after while he heals.

A character seems to have tuberculosis. In S2:E12, his coughing and wheezing are really severe.

A character gets shot in the eye and survives, but loses his eye.

The main character is a nurse and often to be seen fixing dislocated limbs and also broken bones

A baby is stillborn.

The main character travels in time and cheats on her husband, it is technically the main story

A main plot point of season 3 is the kidnapping of the main characters nephew.

In season 4, a doll burns

Jamie’s dad has a heart attack and dies while seeing Jamie being publicly flogged and (mistakenly) believing his son has died from this.

Not in the traditional, horror movie sense, but there are scenes that come out of nowhere that can frighten some viewers. For example, at the start of 2x02 Jamie fantasizes about stabbing Randall, this is very sudden as the viewer doesn’t even realize this is a dream at first.

S4:E1 opens with a brief scene of a character showering.

Jamie does in 3x06

yes there is farting especially in season 1 from Geillis' husband

S1E5 : Claire visit prison. Happens when she go out. S1E16 : Jamie spits blood when Randall removes the nail AND Claire when she go out after she heals Jamie's hand. S3E9 : Jamie seasick. Happens after we saw captain dining with his guest. AND Right after, same scene. AND Claire arrives in the English boat and go to see the sick ones. Near 8 last minutes. Graphics and sound. S3E10 Jamie seasick. When Fergus brings him food. Nothing i remember in 4th and 5th season. (Sry for my poor English)

Claire goes to the hospital when she's about to give birth. The physicians verbally belittle her and inject her with anesthesia against her will.

MANY needles throughout the show because the main character is a surgeon

not yet in the tv show but in the book series a child has cancer

multiple main characters have anxiety attacks/PTSD from rape and war

Not actual self-harm but the cuts on Jamie and Claire's wrists for the marriage bond in 1x07 are shown and they look exactly like self-harm cuts--horizontal across the wrist. It's only a split second shot though and the context is positive.

Prince Charles says he'll take his own life if he doesn't win the throne and is exiled to somewhere like Poland. He's just being dramatic as usual and the line is for humor. Nobody makes suicide threats in earnest.

Almost everyone in this show alludes to experiencing post traumatic stress.

Not exactly die because neither get to go through with it. Fergus tries to kill himself by slitting his wrist in 6x03 but Jamie rescues him in time. Young Ian clearly considers suicide in 5x08 when he takes Claire’s hemlock, but Roger stops him before he can really try anything. In season 1, Colum asks Claire for assistance in ending his own life.

Jamie refuses to eat in an attempt to starve himself after being tortured by Randall. However, he does overcome this.

Lots of squishy sounds as part of injuries and surgeries. High-pitched discordant noises meant to indicate emotional tension. Infants crying. Lots of audible breathing and kissing.

Beginning of S5E3

Briefly in the first episode of the first season. It isn’t so bad after that.

Germain in 4x11 and Jemmy in 5x02 (I think)

there is a very graphic/emotionally traumatic miscarriage scene in season 2

Claire has a very traumatic misscariage, and her daughter Faith is stillborn

A pregnant woman dies in childbirth in season 3, but its not shown on screen, only alluded to

There is discussion about women taking certain herbs/tinctures to end their pregnancies. Nothing is shown regarding it, but the subject does come up numerous times throughout the series.

It is also a miscarriage, very emotional and traumatic for the main character

S4 slavery in America is a theme during this season and the word is casually used by some characters.

There are three characters openly attracted to men, at the time of writing this 9/2020 two are dead and one is alive. Both of the dead individuals were also fairly evil. Two tropes in one.

In 5x09 Jamie faces amputation after his leg is bitten by a snake and acts like loosing his leg is worse than dying. It could come off as offensive since Jamie’s brother in law, Ian, only has one leg, and Jamie’s adopted son Fergus, only has one hand. He does get called out on it by Young Ian. Throughout the show, Fergus is also made multiple times to feel lesser of a man because of his missing hand when other characters (or he himself) make disparaging comments about his disability (3x10, 3x11, 4x11 and more recently 6x01 and 6x03), and society at that time could be considered fairly ableist. His disability, and the world's general lack of acceptance of it, does make him deeply depressed/suicidal in season 6.

I haven’t noticed any slurs, sorry if this isn’t 100% accurate though. A main villain is revealed to be gay though and people react in varying degrees of disgust and/or confusion.

most of the black people on the show die shortly after they are introduced and are enslaved (season 4)

Throughout the series there are explicit scenes of consensual sex, sexual assault, sex in return for favors, nudity, and sexual jokes.

A character does have a crush on his cousin and offer to marry her, but that was common in the 18th century, it wasn't depicted as a weird thing, or in any detail. The cousin is from the 20th century; she refuses him kindly, and things move on. There's also a bit of awkwardness about meeting one's ancestor and finding them attractive, but it's very passing.

there is a lot of sexual violence on this show and some of the scenes are very graphic. if sexual assault is an issue for you to watch to any degree do not watch the season one finale

I'm not sure why so many people are saying yes, when it's not even over yet. If the show continues to follow the books, then it won't be a sad ending, but even the book series isn't done yet, so...

Flashback scene of a car going off of a bridge in the first episode of season 1

There's a lot of war and gun scenes in the 1700s

A lot of it, one of the first scenes is very bloody and graphic

Claire nearly drowns in the end of 3x12/beginning of 3x13, but Jamie rescues her
