Great Dane is a huge-sized dog breed adored for impressive height, balance of elegance and strength, and a friendly character.

If you have a Great Dane, you might wonder how old your dog is in human years. The same way you'd calculate a huge-sized dog age in human years, you need to know your Great Dane's dog age and then convert it using these estimations:

  • a 1-year-old Great Dane is 12 in human years;
  • by the age of 6 years, a Great Dane is 49 in human age;
  • each subsequent year adds 7-8 years in human years.

Great Danes live from 7 to 10 years. Their average lifespan is 8.5 years (shorter than the average dog's lifespan). They are prone to bloat (a gastric dilatation-volvulus). This health condition can be lethal for a dog. So regular vet check-ups and adopting a dog from a responsible breeder are a must.
