Black Lab Average Weight

Last Updated on November 11, 2023 by Linda Richard

Knowing your dog’s expected weight is important for good health maintenance so – what is the black lab average weight and how does it compare to other dogs? Is there any significant difference between black labs and other Labradors? What are the main causes that can lead to your dog getting overweight or not gaining enough weight?

We’ll cover all of these below as it’s important to know your lab’s expected average weight. This will help you figure out if your dog is growing well if there are any major health concerns in its near future, and whether they may be some current issues you didn’t know about.

How Much Do Black Labs Weigh?

The average weight of an adult male black lab can be anywhere in the 64 to 80 lbs weight range (29 o 36 kg). Female black labs are a little lighter and usually fall between 55 and 70 lbs (25 to 32 kg).

The weight difference should be largely connected to the height of the lab too as this can also vary. Adult black labs are usually between 21 and 25 inches tall (55 to 62 cm) with females being about an inch shorter than makes.

This is important to note for a very simple reason – if your lab is on the upper end of its weight range (~80 lbs / 36 kg) but is at the lower end of the height range (~55 lbs / 25 kg) then your dog is probably overweight even though it’s within the expected parameters. So, it’s recommended that you always juxtapose your dog’s weight to its height. If you’re looking for a weight chart, we’ll include one below to help you make sense of these things more easily.

When Do Labs Stop Growing?

Most labs will stop growing in height around their 1-year birthday. The weight gain usually slows down before that and stops around the 13th month. It’s possible for your dog to keep “filling up” with weight for a few more months after that but that gain should be insignificant. It should also be due to your lab building up muscle mass not from gaining fat.

If your lab continues to gain weight to a noticeable degree well after its 13 or 15-month mark, it’s likely that you’re overfeeding your lab. Insufficient exercise is also a common contributing factor to the problem.

Is There Are Weight Difference Between Black Labs and Other Labradors?

Not really – the main difference between black, yellow, brown, and other color labs is just their coat, not their weight. Long-haired labs should theoretically weigh a bit more due to their excess hair but that’s not a significant difference. For all intents and purposes, all standard-size Labradors weigh the same on average.

Black Lab Weight Chart By Age

The average weight of a Black lab relative to its age is easy to track and is comparable to the weight of other Labradors:

Labrador Retriever Age Male Lab Average Weight Female Lab Average Weight
2 months 10 to 14 lbs (4.5 to 6.3 kg) 10 to 13 lbs (4.5 to 6 kg)
3 months 22 to 26 lbs (10 to 12 kg) 20 to 26 lbs (9 to 12 kg)
5 months 33 to 49 lbs (15 to 19 kg) 35 to 49 lbs (16 to 19 kg)
7 months 51 to 59 lbs (23 to 27 kg) 40 to 55 lbs (20 to 25 kg)
9 months 57 to 68 lbs (26 to 31 kg) 48 to 62 lbs (22 to 28 kg)
11 months 62 to 75 lbs (28 to 34 kg) 53 to 66 lbs (24 to 30 kg)
13 months 64 to 77 lbs (29 to 35 kg) 55 to 68 lbs (25 to 31 kg)
15 months 64 to 80 lbs (29 to 36 kg) 55 to 70 lbs (25 to 32 kg)

To accurately compare your lab’s weight to the chart you should weigh your dog in the morning before breakfast. That’s easily done if you first weigh yourself and then pick up your dog and measure your combined weight. After that, it’s just a matter of simple arithmetics.

What Is The Labrador Ideal Weight?

Anything inside the averages described in the above chart is considered “ideal”. Straying a bit from the averages can also be acceptable from time to time. That is, as long as the straying isn’t caused by (or is allowed to lead to) certain health problems. Even then, however, it’s advisable to get your dog back in its ideal shape.

What If Your Black Lab Average Weight Is Off The Norm?

If your lab is lighter than he or she should be, there are several possible causes of that. The most obvious one is a lack of food so consider whether you’re underfeeding your dog. If not, it could be any of the following:

  • Depression
  • Stress
  • Recovery from injury or illness
  • Ongoing disease
  • Intestinal worms or other parasites

The first two you should probably be able to figure out on your own. Still, even for them and especially for the other few possible causes it’s important that you consult with a vet as soon as possible.

The opposite – and much more common – problem is an overweight lab. This is usually caused by:

Again, the first two you should be able to fix on your own but the latter two necessitate a vet visit.

How Can You Help Your Dog Maintain The Black Lab Average Weight?

The big three tips here may bore you as they are recommended for almost any problem – exercise, diet, and routine vet visits. Regular and adequate exercise will help your lab burn calories and build muscle mass. A proper and well-measured diet will make sure that your dog isn’t gaining any unnecessary weight but receives all its required nutrients.

The rest should be covered by regular visits to a good veterinarian. Doing that should be enough to keep your lab healthy, active, and happy for years to come.

I know that all dog breeds are different, but Labradors exude a special energy, don’t they? I believe everyone deserves the unconditional love of a pet, so my main goal is to make sure you can experience it.
