When do large dogs stop growing?

Large dogs stop growing when they are 12 to 18 months. After then, they will always remain in the same size. They need more time than the other dogs when it comes to growth as they have larger bones. But it doesn’t happen with the smaller dogs.

Size and Breed

If you are talking about growth, then you must remember one thing. And that is every dog’s growth depends on its size and breed. The larger dog needs more time to grow than smaller dogs. It is because larger dogs have large bones. So they need some time extra to have full growth about it.

If you are talking about the smaller dogs, then they don’t need time like larger dogs. After 6 to 8 months, they stop growing. They become fully mature. But there are also some cases where smaller dogs need more time for healthy growth.

  • Nutrition


Some dogs have genetic problems. For that, they have a slower or faster rate at growing. So if your dog has this problem, then make sure to check if the dog parents had also suffered from this problem or not.
