When do Golden Retrievers calm down?

Golden Retrievers calm down at around two to three years old. Many pet parents rave that their Goldens maintain their puppy zeal well into adulthood because their fun-loving nature never wanes, and sometimes it’s one of their most coveted characteristics. But Golden Retrievers’ excitability can also become problematic when you’re trying to get them to follow your lead, so staying positive and keeping a training routine is especially important with this breed.
