Dusty is perpetually cheerful, affectionate, very determined, and very hard-working.

Backstory
Dusty was born in a small town called Lone Springs. As a pup, his favorite thing to do was to spend time with his father's horse, but when he was 6, the horse was taken by *actual* bandits. Dusty, very disappointed, made up his mind that he would get a horse for himself. He loved everything about horses- the pleasure of caring for them, the way they seemed to talk with their eyes, and the thrill of speed when riding. Of course, his parents sadly told him that they would not ever be able to afford a new horse, as most coyotes at the time were very poor. Dusty decided to make money himself. He was very determined, with an eager attitude. In Lone Springs, there were only a few buildings, one of which was a very small general store. The owner, an old wolf named Mr. Henderson, agreed to pay Dusty to help out. He had a feeling Dusty would realize his dream was impossible very quickly and would stop, but he never failed to help out around the store. As Mr. Henderson got older and Dusty grew, Mr. Henderson started trusting Dusty with more and more responsibilities, even leaving Dusty in charge while he was out of town. Lone Springs was the only town for miles around, and it saw many bandits. The situation was so bad many people started moving away from the hole in the wall that was Lone Springs. Dusty continued his hard work at the General Store no matter what happened, staying loyal to Mr. Henderson, and always keeping his eternally cheerful attitude. The profits Mr. Henderson made from his store had always been small, so he was never able to pay very much. Dusty knew, at 17, that he only had a fraction of the money he needed to buy a horse. Instead of turning to dishonest means, as was common for young men in his situation, he decided to spend the rest of his life at the General Store, or until he made enough money.
When Dusty was 18, Mr. Henderson died of old age, leaving the store to Dusty. Although Dusty was sad, he kept the store in as good shape as he could, appreciating any customers that came in (they were becoming more and more rare).
Eventually, Lone Springs only had a population of 4, and the General Store was the only business holding the town together. The majority of the few customers were people passing through Lone Springs. There was nothing Dusty could do to stop it from becoming a ghost town. He did not know of anything else he could do, so he put all his heart into keeping the General Store afloat. One day, more bandits came into the town, and started to steal any assets they could find. They broke into the General Store, thinking it closed, and started taking all the money. Dusty, watching closely from his hiding place, wanted to cry as he saw years of his hard work being taken by the robbers. Fearing for his life, he sneakily crept outside, where he saw the bandit's coach being guarded. Using his coyote cleverness, he sneaked inside, pushed the unsuspecting lookout out of the coach, and then drove it away with all his might, leaving Lone Springs to its fate.
He found the coach full of stolen money and gold, and though he felt guilty about doing the wrong thing, he was thrilled. He removed all the valuables, abandoned the coach, and sold the horses, so he would not be suspected of being one of the bandits, and then he went to a large city, bought himself brand new clothes, found a spirited colt for sale, bought him, named him Arch, and rode off into the sunset.
And the rest, they say, is history. Dusty spent the rest of his life riding his heart out with Arch, who loved it just as much as Dusty did. Dusty always felt guilty about the theft and being rich from the stolen money, but he was never caught, and he knew it was unlikely he would. He was much happier galloping through the open air than living with other people in cities. He had all he ever wished for, and he meant to enjoy it.
