When do labradors stop growing?

Labs usually stop the majority of their growing by the time they reach one year old. During this time it is very important that you are feeding your dog a puppy chow formula food. This kind of food has a lot of nutrients that growing puppies need to insure a good development. It also contains more calories than regular food to support their active lifestyle. After one year, the dogs growth will slow down a lot but it will continue to grow till it hits about 2 years old.
