When are Finnish Lapphunds fully grown?

Finnish Lapphunds are fully grown by 18 months old. They typically reach their full height around 12 months of age, but it can take them until they’re 18 months old to reach their full adult weight. Genetics play a big role in determining their final size, but factors like nutrition and exercise are crucial, too. 

Growth plates, which are areas of developing cartilage at the ends of long bones, generally close around the 12-month mark, signaling the end of major bone growth. When transitioning your Finnish Lapphund to adult food, it’s recommended to start around 12 months. This will ensure they get the right balance of nutrients during their puppyhood. Growth progress check-ups with the vet will also help to confirm they’re on the right track developmentally.
