Common Health Issues in Large and Giant Breeds

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

Great Danes, Rottweilers, Labradors and other big dogs are loyal and strong, but their size affects health.

Growth and bones

Large puppies grow quickly, and too much food or calcium can increase developmental problems. Feed a diet made for large-breed puppies and keep them lean. See large breed puppy feeding guide.

Joint disease

• Hip dysplasia. See hip dysplasia in dogs
• Elbow dysplasia. See elbow dysplasia in dogs
• Cruciate ligament injuries. See cruciate ligament tear in dogs
• Osteoarthritis. See arthritis in dogs
• Panosteitis. See panosteitis in dogs

Screening and breeder health tests lower risk. Keep puppies lean and avoid repetitive high-impact exercise before growth plates close.

Bloat

Deep-chested dogs risk gastric dilatation-volvulus, a rapid emergency. Signs include a swollen belly, unproductive retching, restlessness and drooling. Go to a vet immediately. See bloat and GDV in dogs and bloat prevention.

Heart disease

Dilated cardiomyopathy affects some giant and large breeds, including Dobermans and Great Danes. See dilated cardiomyopathy in dogs. Regular heart checks matter.

Cancer

Osteosarcoma, lymphoma and hemangiosarcoma are more common in some large breeds. See osteosarcoma in dogs and hemangiosarcoma in dogs. Report lumps, limping or sudden weakness promptly.

Neurologic issues

Wobbler syndrome affects some Great Danes and Dobermans. See wobbler syndrome in dogs. Degenerative myelopathy affects shepherds and others. See degenerative myelopathy in dogs.

Lifespan

Larger dogs tend to have shorter average lifespans. Senior care often begins earlier, around age five or six for giants. See senior dog care guide.

Spay and neuter timing

Research suggests timing may influence joint and cancer risk in some breeds. Discuss it with your vet. See spay and neuter pros and cons.

Everyday care

1. Keep weight lean.
2. Feed measured meals rather than free feeding.
3. Exercise steadily and build fitness gradually.
4. Use non-slip floors and ramps.
5. Schedule regular exams and screening.
6. Plan for costs. See dog pet insurance guide

Questions to ask your vet

Ask what screening your breed needs, when to start joint supplements or checks, and how to reduce bloat risk.

Common mistakes

• Overfeeding puppies
• Intense exercise too young
• Ignoring early limping
• Not knowing bloat signs

Troubleshooting

• My puppy is growing fast: ask about feeding and body condition.
• He limps after play: book an exam.
• Her belly looks swollen: go to emergency care now.

A simple plan

1. Feed for steady growth.
2. Keep lean.
3. Screen early.
4. Know the emergencies.

Real-life examples

A Great Dane owner recognizes bloat and gets surgery in time. A Labrador kept lean has milder arthritis. A Rottweiler's limp leads to early diagnosis. Awareness helps.

Big heart, big care

Careful planning gives large dogs more comfortable years.

Feeding for steady growth

Weigh puppies regularly and keep a visible waist. Slow, steady growth is healthier than rapid gains. Avoid calcium supplements unless your vet advises, and split daily food into meals. See bloat prevention.

Costs and planning

Large dogs cost more for medication, surgery, boarding and food. Build a savings fund or compare insurance early, before conditions develop, since pre-existing problems are usually excluded.

The takeaway

Big dogs need controlled growth, lean weight and early screening, and owners should know the signs of bloat.
