Can golden retrievers still continue to grow after a 1 yr old?

Yes, golden retrievers can continue to grow after one year old, but their growth rate significantly slows down. Most golden retrievers reach their full height by around 12 months, but they may continue to fill out and gain muscle mass until they are about 2 to 3 years old. This means they may still gain weight and develop a more mature physique during this time. It's important to provide a balanced diet and regular exercise to support their growth and overall health.
