Mr. Peanutbutter (voiced by Paul F. Tompkins), the star of Mr. Peanutbutter's House, is an anthropomorphic Labrador Retriever who is BoJack Horseman's friend and former sitcom rival and a main character in BoJack Horseman.

He dates and later marries Diane Nguyen. He always wears a V-neck shirt and aviator sunglasses, usually propped up on his head, and is assumed to be between 5'10 and 6'1.


Mr. Peanutbutter, who was born on the Labrador Peninsula, and was the star of Mr. Peanutbutter's House (which BoJack claims to have "borrowed the premise" from Horsin' Around) and has had a stint at filming a celebrity reality show called Peanutbutter and Jelly. He has an especially good relationship with Todd Chavez, and his positive attitude as well as financial resources combined with Todd's outlandish schemes and plans often result in the two starting questionable business ventures, such as a Halloween store open exclusively in January, or buying several hundred strainers. Eventually this has put Mr. Peanutbutter deep in debt, resulting in him becoming a shoestore employee, and later the host of a celebrity game show.

Mr. Peanutbutter has been married three times. His current spouse is Diane, and was married to Katrina and then Jessica Biel in the past.

He is the host of the game show Hollywoo Stars and Celebrities: What Do They Know? Do They Know Things?? Let's Find Out!.


Mr. Peanutbutter's demeanor is constantly energetic, cheerful, and playful. In short, he is a dog seen from the point of view of a cat person. Not only is he constantly positive, he is also a bonehead who has difficulty understanding metaphors or puns. This causes him to crack jokes that instead of being funny, just make people scratch their heads. This causes BoJack to testily try and tell him why his jokes fail, and how to improve them. A life of success, wealth, and fame has meant he has never faced any real challenges or have to make difficult decisions. He also struggles to see that Diane is coming on to BoJack. However, he is not as dumb as he might be letting on - as stupidity is part of his persona, and he can at times show hidden depth. Despite their rivalry, he cares a great deal about BoJack's opinion and admires him for his work on Horsin' Around. True to his breed, he loves tennis balls and has a trunk stuffed full of them, that he presumably finds in parks and hoards.
