Lucky is the leader of the Shelter 17 Pound Puppies unit. According to "The Yipper Caper," Lucky got his name on account of his good fortune. He leads one of the best Pound Puppy units in the world. He's a mix of several breeds and has purple and peachish colored fur. His build is almost like a medium-sized German Shephard with cropped ears, although his father looks completely different.
Lucky is friendly, kind, and professional with a "never give up" attitude. He firmly believes that there is "A pup for every person, and a person for every pup." He doesn't believe in luck, despite his name.
Lucky is shown to have several flaws, and sometimes loses focus on what is important; examples of this are seen in "Rebel Without a Collar", "Snow Problem", "Lucky Gets Adopted" and "When Niblet Met Giblet." He gets along with most animals, but dislikes coyotes and tends to have a bumpy relationship with cats.
Lucky's first real focus episode was "Rebel Without a Collar," where he showed disdain at Cookie's growing relationship with the coyote Fang, and was dismayed to hear she was leaving the Pound Puppies to live in the wild with him.
In "I Never Barked for My Father," Lucky encountered his estranged father Slick. Outraged at being seemingly abandoned by Slick as a puppy, Lucky refused to give him and his partner Chip shelter. Eventually, he learned that Slick did not abandon him, because his owners were not the same people who owned Lucky's mother, and that they had moved away. Every time he saw him, Slick wasn't running from him, he was running to him. He also learned that Chip is actually his half-brother, but was convinced to keep that information between himself and Slick.
In "Lucky Gets Adopted," Lucky was adopted by an odd little girl named Dot, who named him "Mr. Chewy McFluffster." After suffering bone-crushing affection and tutu-wearing humiliation while being teased by Bully Cocker Spaniels, Lucky escaped, but was convinced to return by Cookie, and helped Dot to win her school's talent show. Afterwards, Lucky revealed to Dot that he can talk, explaining to her his work at Shelter 17, and that he needs to be able to come and go when needed.
It is revealed in "Hail to the Chief" that Lucky was once a recipient of the Pound Puppies' World-wide Order of Finderhood award, or "WOOF" for short, the highest honor that a Pound Puppy can receive.
In "Lucky the Dunce," Lucky becames goofy and simple-minded after an accident with Strudel's electronic scrambling laser. During his condition, he and Niblet got along great, and Lucky even told Niblet that he wanted things to "stay this way forever." Ultimately though, Niblet realized that it was best for everyone for Lucky to go back to normal, and Strudel was able to reverse the laser's process and get Lucky back to his old self. A bit later, Lucky thanked Niblet for talking care of him, and told him that he was a good friend.
In "Lucky Has to Move," Lucky discovers that Dot's father is in line for a promotion, which would require the family to move to Florida. Not wanting to separate from Dot, Lucky enlists the Pound Puppies in an attempt to sabotage the demonstration at Dot's father's workplace. They ultimately fail, and Lucky bids his friends goodbye. On the way out of town, the family is stopped by Dot's father's boss, Mr. Stinkman, who (due to the Pound Puppies placing Beardy in his house the night before) decided to have Dot's father stay in the city, and has the whole family move into the company's guest house, which turns out to be right next to Shelter 17. Lucky digs under the house's wall, and happily reunites with his friends.
- Lucky will often shout "Go, dogs, go!" when he and his team are about to start a mission.
- There are hints that Lucky reciprocates the crush Cookie has on him, most notably in "Rebel Without a Collar," "Olaf in Love," and "When Niblet Met Giblet."
- According "I Never Barked for My Father," Lucky spent 5 years, 6 months and 3 weeks without his father.
- In the first episode, Lucky was introduced as a dog who "never gets adopted" by McLeish. However, the last episode of season 1 revolved around him getting adopted.
- According to the label on an official plush toy, his last name is "Smarts", although this name has never been mentioned on the show.
- He has fifteen sisters (as mentioned in "Rebound"), and four brothers (mentioned in "Quintuplets.")
- In "Lord of the Fleas," after he, Cookie, Niblet, and Squirt split up to find Solo and Agatha, it is hinted that he has Arachnophobia (fear of spiders), when he jumps on Cookie's back and yells "Spider!"
- Lucky (albeit without the ability to talk or communicate, and named only as "Smarts") recently made a cameo appearance in issue #6 of the Hasbro/IDW Publishing comic Revolutionaries; here, he is depicted as having been the childhood dog of Mike Power, a disabled boy who became the "Atomic Man" with enhanced limbs and who joined General Joe Colton's Adventure Team (the predecessor to the G.I. Joe task force). As a nod to Pound Puppies, Smarts runs away when Power becomes consumed with studying the object that he eventually reverse-engineered into his artificial limbs.
