When your Schnauzer starts shaking, shivering, or trembling, it’s natural to feel concerned. Sometimes, it’s harmless and cute—like when they’re excited for treats. But other times, it’s a serious sign that needs immediate attention.
In this complete guide, we’ll uncover 11 common reasons why Schnauzers shake (from mild to medical), expert-backed tips to help them, and how to spot warning signs before it’s too late.
🧠 Why Do Schnauzers Shake?
Schnauzers shake due to emotional triggers (like fear, excitement, or anxiety) or physical conditions (like cold, pain, or illness). Understanding when and how they shake can help you quickly identify whether it’s normal behavior or a red flag that needs vet attention.
🐶 Common Behavioral Reasons Schnauzers Shake
1️⃣ Feeling Cold ❄️
Schnauzers, especially Miniature ones, have short coats that don’t provide enough insulation.
When exposed to cold floors, winter walks, or chilly nights, they may shiver to warm up.
✅ Tip:
Use dog sweaters or booties, especially during outdoor walks. A heated pet blanket indoors can also help regulate their temperature.
2️⃣ Old Age Tremors 👴🐕
Senior Schnauzers often experience muscle weakness, joint stiffness, and nerve decline. This natural aging process can cause visible shivering or limb tremors.
✅ Tip:
Regular vet checkups, joint supplements (glucosamine, chondroitin), and low-impact exercise (like short walks or hydrotherapy) can ease tremors and improve mobility.
3️⃣ Over-Excitement 🎉
Does your Schnauzer start shaking when it’s dinner time or playtime? That’s happy trembling! Their small bodies can’t always contain big emotions.
✅ Tip:
Encourage calm excitement with “sit and wait” training before rewards or meals. This keeps energy balanced and behavior controlled.
4️⃣ Nervous or Scared 😨
Loud noises, strangers, vet visits, or unfamiliar places can trigger fear-based shaking. This is a fight-or-flight response where their body releases adrenaline.
✅ Tip:
Use positive reinforcement (treats, gentle voice) and counter-conditioning to desensitize them to fears.
Avoid forcing them into fearful situations—build trust gradually.
5️⃣ Anxiety & Separation Stress 💔
Schnauzers are emotionally intelligent and can struggle with separation anxiety or sudden routine changes.
Constant shaking, whining, or destructive behavior are clear anxiety signals.
✅ Tip:
Create a calming routine with consistent mealtimes, walks, and interactive toys.
Use pheromone diffusers (Adaptil) or vet-approved anxiety wraps to help soothe them.
🩺 Medical Reasons Why Schnauzers Shake
6️⃣ Hypoglycemia (Low Blood Sugar) 🍬
Small breeds like Mini Schnauzers are prone to blood sugar drops—especially if they’re very active or not eating regularly.
Symptoms: Trembling, weakness, confusion, or fainting.
✅ Tip:
Feed small, frequent meals with protein and healthy fats. Keep dog-safe glucose gel handy in case of emergency. Always check with your vet for proper dietary needs.
7️⃣ Canine Distemper (Viral Illness) 🦠
A serious and potentially fatal virus, distemper causes shivering, muscle twitching, fever, and nasal discharge.
It mainly affects unvaccinated dogs.
⚠️ Warning:
If your Schnauzer isn’t vaccinated, see a vet immediately if they’re shaking with additional symptoms.
✅ Prevention:
Keep vaccinations up-to-date and avoid exposure to unknown or stray dogs.
8️⃣ Generalized Tremor Syndrome (GTS)
Also called “White Shaker Dog Syndrome,” GTS is a neurological condition that affects many small breeds.
It’s not painful but causes full-body tremors, especially during stress or excitement.
✅ Tip:
GTS is usually treatable with corticosteroids. Only a vet can confirm diagnosis via tests—never self-medicate.
9️⃣ Seizures ⚡
Seizures can cause intense shaking, stiffness, and disorientation. Afterward, dogs often tremble during recovery due to fatigue and confusion.
✅ Tip:
If you suspect a seizure, record the episode, time its duration, and visit a vet immediately. Avoid touching their mouth but ensure a safe space during the event.
🔟 Pain or Injury 😖
Sudden trembling can indicate pain from injuries, arthritis, or internal issues. Dogs can’t speak, so shaking may be their only signal.
✅ Tip:
Look for other signs—limping, whining, reduced appetite, hiding. Get a full vet examination to identify hidden pain.
1️⃣1️⃣ Upset Stomach 🤢
Digestive upset from toxic foods (grapes, chocolate), parasites, or sudden diet changes can make your Schnauzer weak and shaky.
✅ Tip:
Avoid human foods, feed bland diets (boiled chicken, rice) during recovery, and consult a vet if symptoms persist beyond 24 hours.
