Mr. Mark went to the market with his dog. He rode on a horse to the market, Yet walked. The horse's name was Victory and the dog was from South Africa. What is the name of the dog that went to the market?

Why this works

This riddle plays with the phrasing and the structure of the sentence. The key lies in the phrase "Yet walked," which cleverly suggests that "Yet" is not just an adverb but also the name of Mr. Mark's dog. The detail about the horse named Victory and the dog being from South Africa serves to distract you from the straightforward answer hidden in plain sight. So, when asked for the name of the dog, the riddle cleverly indicates that it's "Yet"!
