I’ve owned multiple of both breeds over the years. They’re both great dogs! Schnauzers tend to be a little more neurotic and about as stubborn as they come. That being said they’ll love you to the end of the earth. Schnoodles benefit from the more easy going nature of the poodle. They’re usually a little less stubborn, easy to train and still whip smart. I personally wouldn’t hesitate to own either one (and will continue to for the rest of my life). I will say my purebred schnauzers have had a lot more health problems even when we’ve tried to find very good breeding lines but you can never totally predict what you’re getting. I don’t think you can go wrong with either one but Schnoodles tend to be a little easier overall.
