When do Labradors stop growing?

Most Labradors reach their adult height and the majority of their adult weight by 12 months. Full muscular and structural development often extends to 18–24 months, particularly in males. Growth plates typically close between 12–18 months.

How much should a 6-month-old Labrador weigh?

At 6 months, a Labrador puppy typically weighs approximately 20–28 kg (44–62 lb), depending on sex and individual variation. Females generally track toward the lower end of that range. Body condition is as important as the number on the scale.

Should I feed my Labrador puppy a large-breed puppy formula?

Yes. Large-breed puppy foods are formulated with controlled calcium levels and energy density that support the steady growth rate appropriate for a large-breed dog. Feeding a general puppy food or adult food during growth can contribute to developmental orthopedic issues.

When should I switch my Lab from puppy to adult food?

The typical recommendation for large breeds like Labs is to transition to adult food around 12–18 months. Check with your veterinarian to assess whether your individual dog is physically mature enough to make the switch.
