There are two deaths - a nose being broken into someone’s brain and they struggle to breathe. Another where someone’s head gets caught in a bear trap and they bleed out choking on their own blood
After about 18 minutes into the film, Diego, the Cane Corso, gets hit hard with a bat to the head. He yelps and whimpers, but survives. Pretty easy to skip ahead, look away, or just mute. Happens right after Becky yells, “Diego, attack!”
After a man has his nose hit up into hit brain a couple of times he starts shaking and coughing up something. Not exactly a seizure but feels seizure like.
A head explodes and the remnants of the jaw are seen afterward. Someone is shot with an arrow throw the cheeks. He spits out teeth after the arrow is pulled out.
