The Great Dane is a giant-breed dog (45 to 90 kg) with moderate energy. The Merck Veterinary Manual lists the breed among those predisposed to dilated cardiomyopathy (DCM) and points to taurine deficiency as a nutritional factor — which makes taurine and L-carnitine relevant in the diet. While he is growing, controlled calcium (up to 1.8%) protects the joints.
In the current My Pet Magazine analysis, the best food for the Great Dane is Purina Pro Plan Complete Essentials (Purina Pro Plan), with a technical score of 91.7/100 (🌟 Superior Quality), calculated with the My Pet Magazine IDNM/IPFI methodology across 49 dog foods reviewed in July 2026.

What to weigh in food for the Great Dane
The Great Dane has two issues that weigh on the choice of food, and both demand extra attention because he is a giant breed.
Heart. The Merck Veterinary Manual lists the Great Dane among the giant breeds predisposed to dilated cardiomyopathy (DCM). That makes it relevant to check whether the food provides taurine and L-carnitine, nutrients associated with the heart's muscle function, and to avoid formulations with a history of association with cases of nutritional dilated cardiomyopathy — always with follow-up by a veterinary cardiologist.
Joints and growth. Being a giant breed, the Great Dane has accelerated bone growth that demands rigorous calcium control while the dog is still developing. FEDIAF limits calcium in large-breed puppy food to 1.8% of the dry matter of the food, so as not to speed bone gain beyond what the forming joints can support — care that helps prevent developmental orthopedic disease (DOD).

Breed profile and predispositions
The Great Dane carries two well-documented predispositions, and each one calls for different nutritional care.
The first is cardiac: the Merck Veterinary Manual — Dilated Cardiomyopathy in Dogs and Cats lists the Great Dane among the large/giant breeds predisposed to dilated cardiomyopathy (DCM). The source points to nutritional (taurine deficiency), genetic and idiopathic causes for the disease — which reinforces the relevance of taurine and L-carnitine in the diet as support for cardiac function, and of avoiding formulations associated with cases of nutritional DCM.
The second is orthopedic: being a giant breed with rapid bone growth, the Great Dane needs calcium control while he is still developing. The FEDIAF 2024 guidelines set the limit at 1.8% of the dry matter of the food for growing large-breed dogs — above that, excess calcium speeds bone formation beyond the pace the joints keep up with, raising the risk of developmental orthopedic disease.

Frequently asked questions about Great Dane food
- Does the Great Dane need a special food?
- He needs attention to two things: the heart and the joints. The breed is among the giant dogs most predisposed to dilated cardiomyopathy, and the puppy's accelerated growth calls for controlled calcium. A good food for a Great Dane provides taurine and L-carnitine for the heart, and calcium in the right measure for the joints.
- Why does the Great Dane's heart need so much attention?
- Because the Merck Veterinary Manual lists the Great Dane among the giant breeds predisposed to dilated cardiomyopathy (DCM). Taurine and L-carnitine in the diet help support the heart's muscle function, always with follow-up by a veterinary cardiologist.
- Why does calcium in the food matter so much for a Great Dane puppy?
- Because it is a giant breed that grows very fast, and his body does not handle extra calcium well during that stage. Excess calcium speeds bone formation beyond the pace the joints can keep up with. FEDIAF limits calcium in large-breed puppy food to 1.8% of the dry matter of the food.
- What is developmental orthopedic disease (DOD) in the Great Dane?
- It is a group of bone and joint problems linked to growth that is too accelerated in giant-breed puppies, dysplasia among them. Controlling calcium and energy in the food during the growth period is the main preventive measure, along with tracking weight and the growth curve.
- The Great Dane has moderate energy — does that change the food?
- It changes it a little. He is not a hyperactive breed like a working dog, but his giant size already demands considerable energy just to sustain body mass. Fine-tuning calories takes second place to the breed's two real priorities: the heart and the joints.
