The cows found in the game are mostly Holstein Cattle and Braunvieh cattle. Cows can be commonly seen grazing in pastures. These animals are passive, and will never attack the player, even when provoked. They use the same model and animations from Red Dead Redemption.
- If a cow is punched it will fall to the ground immediately, despite its size. This is likely intended to simulate the activity known as "cow-tipping".
- When switched to, Trevor Philips may be found waking up, drunk, next to a cow in a pen in Grapeseed.
