Why is a small Schnauzer more stubborn than a big dog?

The full narration of the video.

Your Schnauzer isn't being stubborn—it's at work. The moment something stirs outside, it's first to the door, louder than any big dog. You tell it to stop; it glances at you and keeps barking.

Half the size of a big dog—so why the bigger temper? In one large survey of dog owners, about one Miniature Schnauzer in ten was aggressive toward strangers. Among Labradors in the same survey, it was one in two hundred fifty.

That's more than twenty times the difference. "Bad temper" doesn't explain it—let's trace it backward. Start with something counterintuitive: fierce often means scared. The more a dog fears strangers, the more likely it is to bark and lunge at them.

To a dog knee-high to you, everyone at the door is a giant. Barking first is a way to scare the giant off. But fear alone doesn't explain why it won't stop when told. Go back further, to German farms over a century ago. Back then, the Schnauzer had a real job: catching rats in barns and stables.

Catching rats is a lot like playing goalkeeper. When the ball comes, there's no time to look at the coach—the keeper decides and dives alone. Rats dart out of corners at night, too, while the farmer sleeps and nobody gives an order.

A dog that backed off after one bite didn't last. Farmers kept the ones that made their own calls and wouldn't let go. Generation after generation, not waiting for orders and not backing down became instinct. The Labrador is the opposite. Its ancestors fetched game for hunters, always watching people and waiting for the word.

So the Labrador listens, and the Schnauzer has its own ideas. Neither is smarter—the jobs just asked for different things. There's a name for dogs like this: ratters. Yorkies and Miniature Schnauzers both come from that line of work. A keeper guards a goal; it once guarded a barn. Barking at your door, it's still guarding the gate.

The other half is on us. Small-dog owners tend to be looser with rules—no couch today, cuddled up on it tomorrow. The dog learns: rules are negotiable. Bark a little, hold out a little, and it usually wins. Instinct won't change, but rules can. Get the whole family on one rule, stick with it for a week, reward more and scold less.

These findings come from owner surveys, and every dog is different. When your Schnauzer barks at the door, do you think it's guarding the house, or a little scared?
