What dog breed is a billionaire?

I must confess, I'm somewhat perplexed by this inquiry. The question, 'What dog breed is a billionaire?', seems to mix two entirely different concepts. On one hand, we have 'dog breed,' referring to the various types of dogs such as Labrador, Poodle, or Chihuahua. On the other hand, we have 'billionaire,' a term used to describe an individual with a net worth exceeding one billion dollars. "It seems to me that these two terms do not naturally coexist in the same context. Dogs, being animals, do not possess financial assets or net worths. Billionaires, on the other hand, are human beings who have accumulated immense wealth over time. "Could it be that you are referring to a billionaire who owns a particular breed of dog? Or perhaps there is some hidden meaning or pun intended in this question? If so, I'm afraid I'm not quite grasping the nuance. Could you please clarify your question, or provide some additional context?
