Hello. I'm reading the book titled The Intelligence of Dogs, written by Stanley Coren, and I've come across a quotation I'm not sure is correct. This is the sentence: "You can say any fool thing to a dog, and the dog will give you this look that says, "My God, you’re RIGHT! I NEVER would of thought of that!” — DAVE BARRY. Would it not be more correct to say: "I would have never thought of that" I've heard that adverb placement, such as "never" is fairly free in English, but I've never come across "would of thought". I wonder if it is a typo, a mistake or... Thanks in advance for your kind cooperation.
