The dog doesnt necesarily DIE but he is abandoned--turned out into the street alone in NYC. It still broke my heart so I'm saving you the pain. It happens in S2E6 Maidenform" near the end of the episode.
In Season 2 Episode 12, Joan and her fiancé attend the office, where he goes to have sex with her in Don’s office. She protests, and he persists. It is not a graphic scene, but does show the assault and some elements of dissociation.
In the office a group of people are looking at real crime scene photos (not shown up close) and they speculate if the women victims were raped or just killed by the serial killer. The group is shocked but also are sensation mongering.
A main character steps on a toy halfway up a flight stairs while holding a breakfast tray, tumbles down splatters food, breaks glass, but is ok and immediately recovers.
A child isn't listening and continues to play with a toy at the dinner table, leading to a knocked over drink. The toy gets thrown at the wall by the parent. This is not something you would expect from the parent's character.
There are two deaths by suicide in the same manner - hanging. One shows the man's feet only. The other shows everything and is very graphic. The first guy also appears again though with ligature marks on his neck as someone hallucinates him. Very hard to watch.
