Spot is a competitive intelligence and the coolest kid in school. He is very loyal to Leonard, and will help him in his time of needs. Sometimes, when things go wrong for him, he starts having an episode or exaggerating it. He wants whatever he wants, and does not wanna lose things or games. The only people that know of Spot being Scott are Leonard, Mr. Jolly, Pretty Boy, and Tallulah.
Spot is a blue-furred mutt with a white tummy and a black spot on his back. As a Scott, he wears a little hat, a yellow short-sleeved collard shirt, red pants, glasses, and gray sneakers. He was an homage to Baseman's dog, Hubcaps. As a man, he wore a fancy suit.
Spot enjoys going to school. He is Leonard's best friend and dog. When Leonard was 5 years old, he and his mother got him as a newborn puppy during Christmas time. When he's Scott Leadready, he acts competitive with Leonard and uses his show-offy intellect to impress everyone and make Leonard feel inferior. His instincts kick in when something bad happens to him and he starts having an episode. Whether it's helping Leonard impress Leslie or trying to win a contest, he sticks by Leonard at all times.
Spot was tired of staying at home and wanted to go to school to be closer to Leonard and then, he decided to do so. He named himself Scott Leadready II and became the most popular child in school. Leonard became jealous and his love interest, Leslie started to develop a crush on Scott. Scott told Leonard everything, who agreed for Spot to stay as long as no one finds out. As the show went on, Spot got Leonard yelled at, beaten up, punished, or sent to detention on a daily basis. The principal's cat, Tallulah knows that Scott's a dog.

While Mrs. Boogin, the Pet-sitter is watching soaps, Spot accidentally sits on the remote, turning it to the "Barry Anger show." Barry Anger interviews a "wacko" scientist, Ivan Krank who claims he can transform animals to humans, to Spot's delight. He finds out that Krank resides in Florida.
Spot finds Leonard a few miles out of town. Since no dogs are allowed inside the van, Spot has to dress as he does to school, as Scott Leadready II. As Mary sees one of her students from the school, after a conversation with Scott's "family" (or, Scott in costumes,) she happily takes him along. When they finally reach Florida, Spot/Scott admits to Leonard he came just so he can become a real boy. Leonard agrees to help find this scientist Spot/Scott is looking for.

In One Dog's Junk, Ian shows his antagonistic side to Scott when he mocks him for having a toy that used to belong to Spot as a puppy and which was just sold at a yard sale and Scott goes nuts and they start fighting like animals over the toy. Later, Ian gives him the squeaky burger toy back after outbidding 2 Doofuses on the internet for a rare one-of-a-kind version of the toy and even though Spot becomes friends with Ian again, he just realized he wasted his time when he could have gotten a new, fresh, out of the box squeaky burger toy.

Later, when the dance starts, he gets revenge on Scott by changing the music and having everyone bump Scott endlessly.
Spot/Scott and Leonard have appeared in numerous of Gary Baseman's events and appearances and museums. They have appeared in many of Baseman's paintings and they have been featured as walk around characters at many of Gary Baseman's events, appearances, guest speeches, and more along with Baseman's other characters.
- He and Leonard are the only characters to appear in every episode.
- He was inspired by Hubcaps, Gary Baseman's dog. He would wonder what he would do while he was gone for the day.
- Another inspiration for Spot was from the Superman franchise, being that the people of Metropolis could never recognize Spot or Clark Kent with their glasses.
- Despite being an intellect who can do everything, Scott can be ignorant as he once didn't notice that everybody got T-shirts from the museum and thinks that no one except him got anything.
