Gentle Giants: Everything You Need to Know About Great Danes

4. Great Danes are big

Great Danes can grow to a height of 28 to 32 inches at the shoulder. Males generally weigh between 140 and 175 pounds when fully grown. Females are a bit smaller, reaching an adult weight of 110 to 140 pounds. Yet, these gentle canines seem oblivious to their size and see themselves as lap dogs. Dane puppies grow fast. Owners are often shocked to see that their Dane puppy has grown visibly bigger overnight. They don’t reach physical maturity until around the age of three.
