Rusty (Home on the Range)

Rusty is a minor character and Buck's best friend from Home on the Range. He was voiced by G. W. Bailey.

Personality
Rusty is Sheriff Sam's dog who watches over the town when his owner is away. He is shown to be serious-minded and has little tolerance over Buck's immaturity, although the two are best pals and work together very well.

Role in the film
Rusty is first seen attempting to snap Buck out of another one of his daydreams by whistling and reminds him that it's his turn at tick-tack-toe, which they were seen playing together. Buck becomes distraught, knowing that he will never get a chance to fight bandits, but Rusty tries to reassure him that there are other things that he can do besides be a hero.

Buck is then distracted by Rico, a supposed hero that Buck claims to be one of the best, although Rusty shows little interest. When Rico mentions that he needs a fresh horse to help him capture outlaw Alameda Slim, Buck shows off in front of the Sheriff and Rico, causing Rusty to smack his face with his paw in shame.

Later, Pearl and her three cows face losing their farm due to a debt of money that she hasn't been able to pay yet. Maggie, Mrs. Calloway and Grace decide to capture Alameda Slim and earn the reward money to save their farm, and seek Rusty and Buck for help. Rusty sniffs Alameda Slim's wanted poster several times and states how much they will have to come up with in order to save the farm.

Rusty is last seen when he gets caught inside a rolling barrel that Jeb and Lucky Jack overturned due to their bickering and fighting. The barrel eventually falls into the water trough, with all three of them laughing at the end.
