What Is the Average Weight of a Four-Month-Old Labrador Puppy?

When a Labrador puppy is born, it weighs approximately 1 pound or less. In the first eight weeks of the dog's life, the dog gains around 2 pounds a week. When the puppy is eight weeks old, it should weigh between 11 and 17 pounds. The growth process continues with the puppy gaining about 2 pounds per week until it reaches the age of 26 weeks. At this age, its weight gain rate slows.
