Yorkshire Terrier Barking and Small Dog Syndrome: Why It Happens and How to Fix It

'Small dog syndrome' is a real thing and it is not the dog's fault. It is a set of behaviours, barking, lunging, snapping, trembling, that Yorkshire Terriers get blamed for and that are, almost every time, created by how they are handled. A dog this size is picked up every time something worries them, so they never learn to cope. They are carried past big dogs, so every big dog is met from a height, in arms, unable to move away. They are never told no, because it is cute, so they learn that barking works. And when they finally growl, they are laughed at. Then the trembling, shrieking, snapping Yorkie is called 'yappy', as though it were a breed trait. Same genes as the confident Yorkie down the road. Different handling.

The picking-up problem

Picking a dog up removes their ability to move away, and moving away is how dogs cope with worry. A Yorkie held in arms while a Labrador sniffs at them, or while a visitor looms in for a cuddle, has two options left: freeze, or bark. Most learn to bark first and to bite later. Held dogs also learn something else: that barking makes you swoop in. From the dog's point of view, the barking worked.

The rule: pick up for safety, when a real risk is coming, and put them down again as soon as it has passed. For worry, add distance on the ground instead, and let the dog choose to approach or not. A Yorkie who has learned they can walk away rarely needs to shout.

Three kinds of bark

Alert barking

The doorbell, the postman, a dog outside the window. A terrier's job, and a few barks are fine. Thank them, call them to a mat, pay the quiet. Then manage the stage: film on the lower window, a gate that keeps them out of the front room when you're not there, a routine at the door. A Yorkie who spends the day on the back of the sofa barking at the street gets better at barking. Don't shout; to the dog, you have joined in.

Fear barking

A Yorkie barking and lunging at a big dog on the lead is almost always frightened; a two-kilo dog knows exactly how big a Labrador is. The fix is the same as for any reactive dog, scaled down:

• Find the distance where the dog can still take a treat. That might be across the road, or across the park.
• Reward for looking at the big dog, then for looking back at you. The big dog starts to predict cheese.
• Close the gap over weeks, a metre at a time, on the ground, on a loose lead on a harness.
• Never a yank, never a collar, never a shout, never scooped up mid-bark. A yank on a collar is a yank on a windpipe, and it pairs the big dog with pain.

Demand barking

Barks at you while you cook. Barks to be lifted onto the sofa. Barks when you stop playing. Learned, because it worked. Wait for one second of quiet, then pay; the barking gets nothing, ever, including eye contact and telling off. It gets worse for a few days before it gets better. That is the dog testing whether the rule is real. Hold the line for a week and it fades.

The trembling

A Yorkie who trembles in a new place is either cold or frightened, and often both. Check the temperature first: a two-kilo single-coated dog shivers below about ten degrees. If it is fear, the answer is not a cuddle, which teaches nothing, and not forcing them forward, which teaches the world is dangerous. It is distance, time, treats for looking, and the chance to walk away. Confidence is built on four feet.

Carried everywhere versus walking

An adult Yorkie needs thirty to forty-five minutes of walking a day on their own feet, plus sniffing and a chase game. A dog carried in a bag to a café has been nowhere and learned nothing. Walking builds muscle for the kneecaps, confidence for the brain, and tiredness for the evening. Carry them when the pavement is baking, when it is below freezing, or through a crowd. Otherwise, the lead.

The first growl and the honest line

When a Yorkie growls, at the brush, at a hand reaching to pick them up, at a child, don't punish it and don't laugh. A growl is information, and punishing it teaches the dog to skip the warning. Work out what worried them, go back to teaching handling as a game, and get a force-free trainer in early if it happens twice. A snapping two-kilo dog is easy to dismiss, and that is how it becomes a biting ten-year-old. A Yorkie who has bitten needs a qualified behaviourist and a vet to rule out pain, especially dental pain, which in this breed is behind more snapping than anyone realises. The teeth guide explains why.
