Great Danes stop getting taller between the ages of 18 to 24-months. Most reach their full height at 18 months, however, some reach this milestone at 24 months. 

The Great Dane’s height is influenced by their growth plates which are soft cartilage tissue found at the end of their long bones.

The growth plates multiply in cells, increasing a Great Dane’s height. When the growth plates close, the Great Dane stops getting taller and reaches its maximum full height.

How long before a Great Dane is fully grown?

A Great Dane is fully grown when they are between 18 – 24 months old. At 24 months or 2 years of age, they will have attained their full adult frames with males weighing between 140 -175 pounds and 28 – 32 inches in height, while females being 110 to 140 lbs in weight with a height of 28 to 32 inches. 

How big is a 2-month-old Great Dane?

A 2-month-old Great Dane will weigh between 18 to 26 lbs and 13 to 18 inches in height. Most Great Dane puppies will be around his height and weight however this is an estimate because different puppies grow at different rates even those from the same litter. 

How many growth spurts do Great Danes have?

Great Danes have one large growth spurt that occurs between 4 – 6 months of age. Rapid growth is experienced where they increase in height. The Great Dane puppy may experience mild growing pains during this time.

Great Dane Growth Spurt Symptoms

The Great Dane experiences growth spurt symptoms around the age of 4 – 6 months. During this time they are rapidly growing, gaining 2 inches in height per week. They may look skinny with not a lot of muscle, which is quite normal.

Most of their muscle gain starts from 18 – 24 months long after the growth spurt period to build their adult frame. 

The Great Danes growth spurt symptoms comprise of :

  • Lethargy
  • Loss of appetite
  • More sleep than usual
  • Constant hiccups
  • Frequent whimpering with no calls

Some of these symptoms may go unnoticed while they go through this phase. The symptoms are a normal part of life and go away as soon as the puppy completes this growth stage.  

During their growth spurt period, feed them the appropriate large or giant breed dog food to provide the necessary nutrition needed for healthy development.

However, do not overfeed them because being overweight puts pressure on the developing bones and joints, and overfeeding as well as over-exercising them may lead to the development of orthopedic disorders such as hip dysplasia.

Follow the right feeding quantities and frequency of meals per day which changes depending on their age as they continue growing.

It is also always best to consult your vet for a physical examination of your puppy to rule out any infections or diseases that may also contribute to similar symptoms.
