How big Labradors get

Most grown Labradors weigh 55 to 80 lb, males more than females, which puts them in the large size group. Pupsize follows that group's growth pattern from your own puppy's age and weight, so a bigger or smaller Labrador gets its own range.

For example, a Labrador puppy of 20 lb at 12 weeks is about 30% of its grown weight. Grown, it will likely weigh 50 to 84 lb. At 6 months it will likely weigh 34 to 57 lb, and most large dogs finish growing at 12 to 18 months. Buy a 42-inch crate now and use the divider, with a size S harness and a size S collar for today.

How accurate is this Labrador weight chart?

It's a typical figure for the large size group, not a breed standard. The younger the puppy, the wider the range: weigh again in a few weeks and the range narrows.

What collar size for a Lab puppy?

At 12 weeks most Lab puppies take a size S collar, about 10 to 14 inches around the neck, and move to M within a few weeks.
