B-Dawg enjoys hip-hop, bling, and rap. He usually ends his sentences with "Dawg." His catchphrase is "I am the ultimate P-U-P!" B-Dawg is always trying to show off and make everyone think he's not scared, though in reality, he actually is. When he's talking to his brothers and sister or his mom, he always talks in slang, which often perplexes them. He is sometimes rebellious, as shown the first film when Mrs. Niggles told them to rest, he said, "No one tells B-Dawg he has to take a nap." He lives in Fernfield, Washington, with his famous all-star father Air Bud (Buddy) and his mother Molly. His owner is Billy, a boy who is into music and dancing.His attempts to convince his siblings he's not a scared cat often lead him to do dangerous things,such as when he summoned the Halloween Hound from Warwicks mirror by saying his name three times.He did however come up with a plan to defeat the hound. In Snow buddies,Shasta called him along with Buddha the fastest of the group.Thus in the race they were in the middle of the group. In Santa buddies he had to replace Shasta as the lead dog so they could pull the sleigh to save Christmas. Because he was the leader his nose turned red so he could light the way, Rosebud called him "Rudog". In Treasure buddies he was forced to give up his bling to Babi the monkey in exchange for help in finding Pete and his Grandpa. However it seemed like Babi decided to give it back as B-dawg was wearing it at the end of the film. In Super buddies the rings of Inspiron gave B-dawg super elastically. Eventually Commander Drex found the puppies and it was up to B-dawg to defend his siblings from his electrical attacks since electricity cannot pass through rubber. The Buddies eventually defeated Drex and returned the rings to Megasis.
Out of all of the Buddies, B-dawg seem's to be closer to Buddha than the others. Buddha is the only one who doesn't make jokes about how scared he get's. In Treasure Buddies the two were part of the same group when they split up to search for Pete and his Grandpa. B-dawg played some music for his brother so he could defeat Slither at a challenge. Also in Snow buddies they were both in the middle of the team, meaning they are the fastest. However, B-dawg does sometimes get annoyed at his meditating. He said in the "buddy bites" that it was boring.
Rosebud and B-dawg disagree a lot about somethings. Like in the Snow buddies "Buddy bites" Rosebud told B-dawg to "get over himself" after he kept on boasting. She was also frustrated when he ran in the ice cream truck instead of standing guard. But they do still have a good relationship. For example in Snow buddies B-dawg only confessed to Rosebud that he was scared of the race because of what happened to Shasta's parents but she re-assured him that it will be fine.
B-dawg and Budderball are, like the others, close. But they sometimes have arguments. B-dawg shouted to him, in Air buddies, "why don't you stop thinking about your stomach for once" leading to a small fight. Like the others, he always yells "don't pull his paw!" whenever someone is about to pull it because he releases gas then.
Mudbud and B-dawg had a small squabble in Air buddies while they were running behind the projector which was showing 101 Dalmatians at a drive in theatre and again got into a fight in the woods because they were annoyed at each other. They both like being cool but with a few differences. Mudbud likes "hanging loose" while B-dawg prefers to show of how cool he can be.
B-dawg takes after his father in that he loves playing basketball.
B-dawg's mum sometimes tries to use slang words when she talks to B-dawg so he can better understand her.
B-dawg and the other buddies first met Shasta in Alaska, Snow buddies, and they all became close friends with him. B-dawg agreed, with the others, to form a dog sled team to help Shasta and Adam accomplish their dream as well as getting to the airport. Shasta put him and Buddha in the middle of the team because they are the fastest. B-dawg was sad when they had to say goodbye to him and said to their husky friend "Shasta, your now officially part of my posse"
