This movie contains 1 potentially triggering events.
The dingo (not exactly a dog), but the protagonist's pet, does not die nor we see him getting hurt. We just learn that he has been lightly hurt in the head.
Off-screen. Someone gives the pet dingo Boswell a barely visible wound on his head to send a message to the protagonist. He is never shown hurting or whining from pain. Good Boy Boswell is just fine for the rest of the movie (other than getting launched out of his seat from a sudden brake-stop of the truck.
In the very last shot of the movie there is a jumpscare where a severed head falls down, it doesnt add anything you can just stop watching before then.
