The Pound Puppies
Voiced by Eric McCormack
- Catchphrase: "Go dogs, go!"
- Determinator: No matter what, he will never give up on getting a puppy adopted.
- Disappeared Dad: His father Slick would often disappear for several days. One day he never came back at all.
- Daddy Had a Good Reason for Abandoning You: As Lucky's father Slick explained in "I Never Barked For My Father", Lucky had to stop thinking about it as a puppy and think about it from his father's perspective, or for you as the viewer, as Slick's role as a pet. Slick was actually the dog of the neighbors of Lucky's mother's humans, not of his mother's humans as Lucky thought. When the neighbors moved across town, they naturally took Slick with them.)
- Expy: He serves as this continuity's equivalent of Cooler, being the laid-back leader of the Pound Puppies.
- The Hero: He is the main character of the series and is the one in charge.
- Ironic Name: His name is Lucky, but he doesn't believe in luck.
- Nice Guy: One of the nicest characters on the show. He gets along with just about everyone.
- The Leader: Of the Pound Puppies.
- Oblivious to Love: In "Olaf In Love". Though both he and Cookie nervously denied their feelings when Kiki, the featured puppy, made mention of them being "more than friends", Cookie pointedly brought up of Lucky's blindness to her feelings (and his own?), in relation to Olaf dating city librarian Gertrude Washburn.
- When You Coming Home, Dad?: When Lucky was a puppy, his father would be gone for hours or even days at a time, until one day he left for good. As noted above, this is because his dad belonged to another family.

- Berserk Button: Do not touch her belly.
- Catchphrase: "Get off my belly!"
- Deadpan Snarker: She won't hesitate to make sarcastic remarks when she gets the chance.
- Expy: She is similar to Nose Marie from the 1980's cartoon, particularly due to being a brown-furred dog with a pink bow who has a crush on Lucky, himself an expy of Cooler.
- Jerk with a Heart of Gold: She's blunt, stern and brash, but still pretty nice.
- The Lancer
- Mama Bear: With Cupcake.
- Sassy Black Woman: Downplayed. While she lives with a multiracial family with a black father, none of them speak in the manner that she does.
- Tertiary Sexual Characteristics: Cookie is a bit more complicated. At first, she didn't have anything, other than her eyelashes. (Her collar is black.) After seeing Dolly flirt her way into getting the male dogs to fawn over her in the episode "The General", she becomes jealous. By the end, Dolly gives Cookie the pink bow that she's seen with from that point on.

Squirt told her that we once had a friend whose owner left and never came back.
- The Napoleon: A chihuahua with a bit of a temper.

Lucky's long-lost father.
- Daddy Had a Good Reason for Abandoning You: He didn't have much of a choice. He belonged to the neighbors, not the owners of Lucky's mother. He made attempts to get back to her and the pups.

- Elopement: Before moving away, he asked Lucky's mother if she wanted to take the pups and leave their owners, but she turned it down, believing that a dog's place was with their people.
- Good Parents: Lucky believed the contrary up until Slick reveals that he wanted to be a part of his life, but couldn't due to circumstances outside of his control. To make up for it, he's been trying to be a good father to Chip, though Chip is unaware of his parentage.
- I Want My Beloved to Be Happy:
- He lets Lucky's mother and Chip go, because they want to stay with their owners while he doesn't agree with the lifestyle anymore.
- He never tells Chip that he's actually his father so that he doesn't resent him like Lucky does.
- Lovable Rogue
- Luke, I Am Your Father: It turns out that he's also Chip's father, though he asks Lucky to refrain from telling Chip this as he doesn't want Chip to resent him like Lucky did.
