About the Great Dane
The Great Dane is a gentle giant — patient, friendly, and enormous. As a giant breed, the Great Dane ages very fast and has one of the shortest lifespans of any dog.
Caring for a Great Dane
Growth. A Great Dane grows from a tiny puppy to a huge adult in about a year. Feed a proper large-breed diet to support safe growth.
Joints and bloat. Keep a Dane lean to protect the joints, and learn the signs of bloat — a real emergency for deep-chested breeds.
Senior years. A Great Dane is a senior by about age 5 to 6. Giant breeds age fast — every year truly counts.
