Brian Griffin (Earth-8999)

Brian Griffin is the anthropomorphic Labrador Retriever of the Griffin family, where the acts as the best friend of Peter Griffin, but, since the years, more of the best friend of the family baby Stewie Griffin.

Early Life
Stewie was born as one of the seven puppies of the Labrador Retriever Biscuit, a dog who lived in a farm on Austin, Texas. Brian was the only puppy who was mysteriously able to talk, which made him distant from his brothers and sisters; while they only wanted to play, he wanted to write and ask questions about everything around him.

He was eventually taken by Biscuit's owner and sent to dog adoption. He was adopted by an abusive family, but he ran away, and he entered Brown University, where he planned to become a writer upon graduation. Unfortunately for him, he failed his last test and was forced to back off, becoming a stray dog at the streets of Quahog, Rhode Island.

One day while asking for food, Brian met Peter Griffin, who decided to adopt the dog as part of his own family. He drove him to his home and he was welcomed to the family.
