Your Great Dane is shaking and panting, and you’re worried. Let’s get straight to it: these symptoms can stem from simple stress or overheating, but in a giant breed, they can also signal an emergency like bloat (gastric dilatation-volvulus) or heart trouble. While occasional panting and trembling after exercise is normal, persistent or sudden onset warrants immediate veterinary attention. Here’s what you need to know.
Common Causes: When It’s Not an Emergency
Stress and Anxiety
Great Danes are sensitive souls. Thunderstorms, fireworks, separation, or new environments can trigger shaking and panting. This is often accompanied by pacing, whining, or hiding. If your dog settles once the stressor passes, it’s likely anxiety. Provide a safe space, calming music, or a thunder wrap. For severe anxiety, consult your vet about behavior modification or supplements.
Heat and Overheating
Danes overheat easily due to their size and short coats. Panting is their main cooling mechanism, but excessive panting with drooling, red gums, or lethargy points to heatstroke. Always provide shade, fresh water, and avoid exercise in hot weather. Never leave your Dane in a parked car.
Excitement or Play
A vigorous play session or greeting you at the door can cause temporary shaking and panting. This is normal and resolves quickly. Offer water and a rest break.
Medical Causes: When to Act Fast
Bloat (GDV)
This is the #1 killer of Great Danes. Shaking, panting, a distended abdomen, unproductive retching, and restlessness are classic signs. GDV requires emergency surgery. If you see these signs, rush to the vet immediately.
Pain
Joint issues like hip dysplasia or arthritis, injuries, or post-surgical pain can cause trembling and heavy breathing. Your Dane may limp, avoid stairs, or be sensitive to touch. Visit your vet for pain management.
Heart Problems
Dilated cardiomyopathy (DCM) is common in Danes. Symptoms include panting, coughing, weakness, and fainting. A vet can diagnose via echocardiogram and prescribe medication.
Other Illnesses
Fever, poisoning, metabolic disorders, or neurological issues can also cause these signs. If accompanied by vomiting, diarrhea, or collapse, seek emergency care.
When to Call the Vet Immediately
Call your vet or an emergency clinic if your Great Dane’s shaking and panting:
– Comes on suddenly and severely
– Is accompanied by a swollen or painful belly
– Includes vomiting, retching, or diarrhea
– Shows pale or blue gums
– Causes collapse, weakness, or inability to stand
– Persists for more than 30 minutes without clear cause
Always trust your gut. You know your dog best. When in doubt, a vet check is the safest course.
What You Can Do at Home
- Stay calm. Your dog picks up on your stress.
- Check for heat. Move to a cool, shaded area and offer water.
- Inspect for injury. Gently feel for tender spots or swelling.
- Provide comfort. If anxiety is likely, create a quiet den with their favorite toys.
- Avoid home remedies. Do not give human painkillers or anxiety meds without vet approval.
