Scientist Bruce Banner scours the planet for an antidote to the unbridled force of rage within him: the Hulk. But when the military masterminds who dream of exploiting his powers force him back to civilization, he finds himself coming face to face with a new, deadly foe.
The dog is shot with a tranquilizer dart so I assume he doesn't die, but he isn't seen in the movie again. Maybe he wakes up and finds a new home (fingers crossed).
Netflix timing 01:03:39....I wouldn't even really classify it as vomiting coming from an extreme emetophobic you just hear Bruce gagging loudly in the bathroom no visual as the camera is on Betty. If you're really concerened just mute when you see Bruce in the shower curled up and unmute when he opens the door with a toothbrush in his mouth.
There is some slight body horror (which is entirely different), but the titular character does often express hatred for his ability to become the Hulk and continually tries to find a way to cure himself.
No, but it is worth mentioning that a deleted scene had the main character attempt suicide by gunshot. "The Avengers" has reference to this scene, implying it did happen at some point, however.
