14-Karat is a Golden Retriever with golden-brown fur. He wears an orange collar with diamond-shaped tog tag. While on Mr. B's Farm, he had a yellow, circular dog tag with the number 1 on it.
14-Karat is rather impulsive; this was shown when he opted to attack the Gold Monster directly, which resulted in him being turned into a gold statue until the monster was caught. It turned out that he was fine because the "gold" that covered him was actually Shutdown Goo that peeled right off.

Mr. B used the money the puppies won in the dog show to buy a farm. But the attacks of the Demon Farmer got the attention of an activist who was trying to get them away from the farm for their safety.
