Newfoundlands typically stop growing in height around 18 to 24 months of age, though they may continue to fill out and gain weight until they are about 2 to 3 years old. Their growth can vary based on factors like genetics, diet, and overall health. It's important to monitor their growth and ensure they maintain a healthy weight throughout this period. Regular veterinary check-ups can help track their development.
