This might seem a little obvious but it just occurred to me the other day. Bojack is a horse, horses used to be animals that were used all the time. But as time went on people used them less and less with the rise of automobiles. Eventually horses fell out of popular use. I could see this maybe being an analogy for Bojack, his rise to fame and then his fall into insignificance. What do you guys think, was it intentional?
I think there are certain traits that the main anthropomorphic characters took from their animal. Bojack’s appetites, Mr. Peanutbutter’s blithe optimism, PC’s tenacity and ability to land on her feet, etc. I don’t think the symbolism is hidden so much as it makes for a convenient storytelling tool.
