Great Dane Not Eating (Anorexia): What To Do Right Now
If your Great Dane is not eating, you need a real answer, not ten articles that all say "see your vet." This guide tells you exactly what is likely happening, what to do in the next 30 minutes, and when this requires emergency care.
MONITOR CLOSELY
Monitor carefully for 24 hours. See a vet if symptoms worsen or do not improve.
Go to Emergency Vet Immediately If You See Any of These
- !cats not eating for more than 24 hours (hepatic lipidosis risk)
- !dogs not eating for more than 48 hours
- !weight loss visible in a short period
- !not eating alongside vomiting, diarrhea or lethargy
- !drinking significantly more or less than normal
- !hiding behavior alongside appetite loss in cats
What Causes Not Eating (Anorexia) in Great Danes?
- stress from environmental changes (moving, new pet, new baby)
- dental pain (tooth root abscess or broken tooth)
- nausea from medication or vaccination
- gastrointestinal disease
- respiratory infection (cats especially stop eating when they cannot smell)
- underlying organ disease (kidney, liver, or pancreas)
- pain from injury or orthopedic disease
- behavioral or psychological causes
Is My Great Dane's Not Eating (Anorexia) Serious?
In the US, the most overlooked cause of appetite loss is dental disease. Studies show 80% of dogs over 3 years have some degree of periodontal disease causing pain at mealtimes. The second most common cause in cats is upper respiratory infection. Hepatic lipidosis from not eating is the leading nutritional disease in US cats.
Diwali and festival seasons cause significant anxiety-related appetite loss in Indian pets due to firecracker noise. Indian summer heat above 38 degrees C also suppresses appetite in dogs. These are common non-emergency causes. If symptoms persist beyond the event, consult a vet.
Specific to Great Danes
Great Danes are at extreme risk of bloat (GDV), a life-threatening emergency. Never exercise within 2 hours of meals. Feed from an elevated bowl and give multiple small meals.

Frequently Asked Questions
My Great Dane is not eating. Is it serious?
Great Dane not eating ranges from mild to serious. Watch for these red flags: cats not eating for more than 24 hours (hepatic lipidosis risk); dogs not eating for more than 48 hours; weight loss visible in a short period. If none are present, monitor closely for 24 hours. Great Danes are at extreme risk of bloat (GDV), a life-threatening emergency. Never exercise within 2 hours of meals. Feed from an elevated bowl and give multiple small meals.
What causes not eating in Great Danes?
The most common causes of not eating in Great Danes include stress from environmental changes (moving, new pet, new baby), dental pain (tooth root abscess or broken tooth), nausea from medication or vaccination, gastrointestinal disease. Great Danes are also prone to bloat (GDV) and dilated cardiomyopathy, which can contribute.
How much does it cost to treat not eating in a Great Dane?
Hepatic lipidosis treatment: $1,500-$4,000. Dental disease treatment: $300-$2,000. Early dental check: $150-$300. Early assessment costs a fraction of treating a condition that has progressed. Omelo helps you determine urgency before spending on an emergency vet visit.
When should I take my Great Dane to the emergency vet for not eating?
Cats must see a vet within 24 hours of not eating. Hepatic lipidosis can develop and become life-threatening within 3-4 days. Dogs should see a vet within 48 hours. Both need same-day care if other symptoms are present.
Can I treat my Great Dane's not eating at home?
For mild cases without red flags: Warm food slightly to enhance aroma and palatability. Try a different protein source or food texture temporarily. Ensure water is fresh and change it multiple times daily. If symptoms have not improved within 48 hours, see a vet.
How does Omelo help with my Great Dane's not eating?
Omelo tracks daily meal consumption as part of the standard health log. When appetite drops, Omelo compares it against your pet's 30-day baseline and flags deviations, often before you notice a full day has passed without eating.
Why are Great Danes more prone to not eating than smaller dogs?
Great Danes are at extreme risk of bloat (GDV), a life-threatening emergency. Never exercise within 2 hours of meals. Feed from an elevated bowl and give multiple small meals. Beyond that, Great Danes are prone to bloat (GDV), dilated cardiomyopathy, hip and elbow dysplasia — any of which can contribute to or worsen not eating. The Great Dane is the popular giant breed in the united states, so US veterinarians see this combination frequently and protocols are well established.
Is not eating an emergency in Great Danes?
Not usually, but watch for red flags: cats not eating for more than 24 hours (hepatic lipidosis risk); dogs not eating for more than 48 hours. In a Great Dane, the breed-typical bloat (GDV) risk means even moderate not eating should be tracked, not ignored.
