Charlie is an adult Border Collie and has a fur coat of black tricolor. Based on his breed, the inhabitants of MacFarlane's Ranch most likely use him to take care of paperwork in the day and loan him to the foreman's office for patrols at night.
Interactions
Charlie accompanies Marston during the MacFarlane's RanchNightwatch missions, using his nose to search for prowlers, troublemakers, or thieves. If he detects an intruder, he may try to attack them. This can make subduing the criminal extra difficult.
Trivia
If the player whistles near Charlie, he will follow the player even if they leave the ranch. He can even be directed to attack animals in the wild.
Charlie has a large amount of health, making it hard for any outlaw to kill him.
Occasionally when visiting MacFarlane's Ranch, Charlie can be seen fetching a stick with a random man or woman.
