Growth Chart Great Dane

Coined the “Apollo of Dogs,” according to the American Kennel Club, or AKC, the Great Dane is a magnificent giant dog breed, known for its friendly nature and gentle patience. It’s not surprising, though, if the first thing that comes to mind is the sheer size of the breed. The Great Dane growth chart estimates weight and height for Great Dane puppies up to adults and includes adult male and female weight and height numbers. Learn how big and tall a Great Dane could grow to help you determine if the breed is right for you and your family.

Consider the general growth rate for puppies of various breeds as you weigh the pros and cons of adopting a Great Dane puppy. What is the average growth rate of a puppy? When will they reach their adult size? We consulted our veterinarian, Dr. Jennifer Coates, about the average size and weight of Great Danes over their lifespan. After Dr. Coates reviewed and approved the data, we created this handy Great Dane growth chart. A Great Dane’s weight and height are typically higher than other breeds, even during puppyhood. Check out our Great Dane puppy weight calculator to give you some guidance.

At what age is a Great Dane full grown?

Great Danes grow quickly, with their largest growth spurts occurring around four to six months of age. Per the Great Dane Club of America, Great Danes grow as much in one year as a human will grow in their first fourteen years!

Great Danes are considered fully grown between 18 and 24 months of age. Most Great Danes will reach their full height by 18 months and continue adding muscle during their second year.

This article explores the growth patterns of a typical Great Dane. However, remember that your puppy’s results may vary. They may have growth spurts or plateaus that speed up or slow down overall growth. This is normal and is no cause for worry. Great Danes typically reach their full height at eighteen months old, though their weight continues to develop until they are 24 months old. This growth also depends on nutrition and overall health, so be sure not to overfeed or underfeed your dog. You must also keep them away from injury. Ultimately, your puppy might be slightly smaller or larger than the averages we provide. If you find yourself alarmed by this, it’s always a good idea to contact your veterinarian.

Every dog is unique; some may be bigger than the breed standard, while others may be smaller. Measuring them allows us to see if our dogs are on track. Some grow bigger faster, whereas others take longer to grow up. Keeping note of milestones gives us points of comparison to see just how well our dogs are developing. There are a few different factors that go into our dogs’ growth, regardless of gender or breed.

Here is a timeline of your Great Dane’s growth, plus the different developmental milestones and things your puppy may need at these times.

You should continue your puppy’s training and socialization, but it may be a good idea to start leash training them now to get used to the feel of the harness and leash. Ideally, you should prepare your Great Dane not to pull on the leash, or else he will be walking you. This is also a right time to get them used to grooming. Consistency and patience are key here, so be sure to treat your puppy fairly. They are very playful and particularly mouthy. Do your best to curb bad behavior and encourage acceptable behavior.

Puppies who were not well for an extended time may have stunted growth. Poor health does not allow the body to reach its highest potential, so you should always check in with your veterinarian to ensure that your puppy is as healthy as possible. Injury can also be a factor in the growth of a Great Dane. Do not allow them to overexert themselves as they are growing. Always give your dog plenty of space to play so they don’t accidentally bump into anything and hurt themselves in the process.
