Why Is My Yorkie Shaking? 8 Causes & What to Do

Yorkies shake for many reasons — most are benign, but a few are urgent. The most common causes are cold (their tiny bodies lose heat fast), hypoglycemia (low blood sugar, very common in toy breeds), anxiety, and excitement. Constant shaking paired with lethargy or vomiting needs a vet the same day.

8 Reasons Your Yorkie Is Shaking

Yorkies are one of the most shiver-prone breeds — their fine silky coat provides minimal insulation, their metabolism runs hot and fast, and their temperament is genuinely high-strung. That combination means shaking is common, but context determines whether it's harmless or urgent.

Is Your Yorkie Cold?

Yorkshire Terriers weigh 4–7 lbs at most. That tiny body mass means heat escapes quickly, especially in air-conditioned rooms, after a bath, or on a cool walk. If the room is below 68°F or your dog has been outside, cold is the single most likely explanation.

Fix: Wrap your Yorkie in a blanket, move to a warmer room, or put them in a dog sweater. The shaking should stop within a few minutes.

Could It Be Low Blood Sugar (Hypoglycemia)?

Hypoglycemia is especially common in Yorkshire Terrier puppies and in adults under 5 lbs. Small dogs have limited glycogen stores and burn through them quickly — a missed meal, stress, or heavy exercise can trigger a dangerous drop in blood glucose.

Signs of hypoglycemic shaking: the dog is trembling AND seems weak, glassy-eyed, or disoriented. This combination is an emergency, not something to monitor at home.

According to the American Kennel Club, toy breeds are uniquely vulnerable because their small liver cannot store enough glycogen to sustain them between meals. Puppies especially need feeding every 3–4 hours.

"Small and toy breed dogs are predisposed to hypoglycemia because they have a faster metabolism and less muscle mass to store glucose. Signs include weakness, trembling, seizures, and in severe cases, coma." — American Kennel Club Health Resources

Fix: Rub honey or corn syrup onto your Yorkie's gums immediately, then call your vet. If the dog is unconscious, go directly to an emergency clinic.

Is Your Yorkie Anxious or Overstimulated?

Yorkies are bold little dogs, but their nervous system is running at full speed most of the time. Thunderstorms, fireworks, strangers, car rides, and even excited anticipation (mealtime, walks) can all produce visible shaking that looks alarming but is purely adrenaline-driven.

You'll know this is the cause when the shaking coincides with a specific trigger and resolves once the trigger is removed. Your dog will otherwise seem alert and happy.

Fix: Remove the stressor if possible. A calming wrap (like a Thundershirt), white noise, or a quiet room often helps anxious Yorkies settle within 10–15 minutes.

Could Your Yorkie Be in Pain?

Pain from dental disease, an ear infection, a back injury, or joint problems can manifest as persistent shaking or trembling — especially if your dog tenses or yelps when touched in a particular spot. Yorkies are prone to luxating patellas (slipping kneecaps), which can cause a dog to suddenly shake one hind leg.

Fix: Run your hands gently over the dog's body looking for tender spots. If your dog reacts to touch in a specific area, schedule a vet visit.

Is It Generalized Tremor Syndrome?

Also called White Dog Shaker Syndrome, generalized tremor syndrome is an inflammatory neurological condition that causes full-body tremors, especially in small white or light-colored dogs. Yorkshire Terriers can be affected. Tremors typically start between 9 months and 2 years of age and worsen with stress or excitement.

Unlike shivering from cold, these tremors don't improve with warmth and can include head bobbing or eyes moving rhythmically. It's treatable with corticosteroids under veterinary supervision.

Has Your Yorkie Eaten Something Toxic?

Xylitol (found in sugar-free gum, some peanut butters, and candies) is acutely toxic to dogs and causes hypoglycemia within 30 minutes of ingestion. Other common toxins that cause trembling include chocolate, grapes/raisins, macadamia nuts, and certain mushrooms.

"Xylitol is a sugar substitute found in many household products. Ingestion by dogs can cause hypoglycemia (low blood sugar), seizures, liver failure, or death." — ASPCA Animal Poison Control Center

The ASPCA Animal Poison Control Center hotline is available 24/7 at 888-426-4435 if you suspect ingestion.

Could It Be Old Age Tremors?

Senior Yorkies (8 years and older) often develop mild tremors in their hindquarters or legs — a normal part of aging as muscle mass declines and nerve signaling slows. Old age tremors are typically mild, symmetric, and don't affect the dog's appetite or energy level.

Fix: No treatment reverses age-related tremors, but maintaining a healthy weight, keeping your senior Yorkie warm, and providing joint supplements can improve comfort.

Is Your Yorkie Nauseous or About to Vomit?

Dogs often shiver just before vomiting. If your Yorkie has eaten something unusual, is drooling excessively, or is repeatedly licking their lips alongside the shaking, nausea is the likely cause.

Fix: Withhold food for a few hours, offer small amounts of water, and monitor. If vomiting continues for more than 24 hours or your dog seems very weak, see a vet.

When to Go to the Vet Right Now

If your Yorkie is shaking AND any of these are also true, treat it as an emergency: lethargic or unresponsive, won't eat, has pale or blue gums, fell or was dropped recently, or ate something potentially toxic.

Brief shaking from cold, excitement, or anxiety that resolves on its own is fine to monitor at home. Any shaking that lasts more than 30 minutes without an obvious cause, or that recurs daily, deserves a veterinary examination.

In Short

Yorkies shake most often from cold, low blood sugar, or anxiety — all of which are manageable at home with quick action. The one that demands immediate attention is hypoglycemia: if your Yorkie is shaking AND lethargic or glassy-eyed, rub honey on the gums and call the vet. Generalized Tremor Syndrome and toxin ingestion are less common but serious. When in doubt, a same-day vet call is always the right move with a dog this small.

What You Also May Want To Know

Why is my Yorkie shaking and acting lethargic?

Lethargy combined with shaking in a Yorkie is a red flag for hypoglycemia (low blood sugar) or pain. Skip home remedies and call your vet — hypoglycemia can deteriorate quickly, especially in puppies and small adults under 7 lbs.

Is it normal for Yorkies to shake?

Yorkies shake more than many breeds due to their tiny body mass, high metabolism, and excitable temperament. Brief shaking from cold, excitement, or anxiety is normal. Shaking that is constant, paired with lethargy or vomiting, or that started suddenly is not normal and needs a vet evaluation.

What do I do if my Yorkie is shaking from low blood sugar?

Rub a small amount of honey, corn syrup, or sugar water on your Yorkie's gums immediately, then call your vet. If your dog is unconscious or seizing, skip the home treatment and go to an emergency vet directly.

Can cold make a Yorkie shake?

Yes. Yorkies have very fine coats and almost no body fat, making them prone to rapid heat loss. If the room is below 68°F (20°C) or your dog has been outside in cool weather, cold is the most likely reason for shaking. A dog sweater or blanket fixes it in minutes.

Why does my Yorkie shake when I pick them up?

Shaking when picked up usually signals anxiety, pain, or overstimulation rather than illness. Some Yorkies dislike being lifted due to a past injury or a sensitive spot. If your dog yelps or stiffens when picked up, have the vet check for neck or back pain.
