If you’re researching a Great Dane to take home, or if you have a Great Dane and are trying to figure out things like what size dog crate to buy or if your dog is the right weight, you’ll want to know how big they get at different stages of life (particularly how much they’ll weigh and how tall they’ll be when they’re full grown).
To help with that, our veterinary advisor, Dr. Jennifer Coates, we created a puppy weight calculator and a series of growth charts (including a Great Dane growth chart). In this post we’ll use that data to answer the questions:
How Much Do Great Danes Weigh? How Big Do Great Danes Get?

How Fast Does a Great Dane Grow?
Great Dane puppies grow at a slightly faster rate than other large and giant-breed puppies. According to the Great Dane growth predictor, a Great Dane puppy is already about 30 pounds by the time they’re 8 to 12 weeks old. In comparison, a Labrador retriever puppy doesn’t reach 30 pounds until they’re almost 4 months old. Of course, a full-grown Labrador also doesn’t get as big as a full-grown Great Dane.
On average, a Great Dane gains 15 to 20 pounds every month from 2 to 6 months old. After that, the rate slows down to about 10 pounds per month, up to about 1 year old. Great Danes will continue to grow, albeit at a relatively slow pace, until they are 18 to 24 months old.
Just like all dogs age faster than humans, large dog breeds age faster than small dog breeds. This concept has sparked a decades-old debate regarding why smaller dogs live longer than larger dogs. Though the science is unclear as to exactly why, the size (height and weight) of the animal does matter. Other factors involved include breeding, health, and cognitive development.1
