How Much Should My Labrador Weigh? Including Weight Charts & Puppy Growth

The average Lab weighs 60-80lbs, but you might be surprised to hear that the number on the scales doesnt actually matter. Its what you see and feel that makes the difference. And today, Ill show you how to work out if your dog is a healthy weight.

A while ago we surveyed members of our Labrador community and compiled the weights of their Labs into the chart below.

There is quite a big difference between individual Labrador puppies and older dogs in each age group! Most people worry at some point that their Labrador might be overweight or underweight so Ill explain how you can tell if your Lab is the right weight, and why there is such a big variation in weight and size in the Labrador breed.

Labrador Puppy Weight Chart By Age

Puppy growth rate is rapid to begin with and tales off significantly after about twenty weeks. Lots of our readers want to know how much should their Labrador weigh at five months, or six months, etc.

We collected the data from our forum to create the Lab weight chart above. For a rough idea of how much your pup should weigh at each stage of their life, you can compare them to this chart. As you can see, variation within each age group is normal.

Average Labrador Weight

As a rough guide, an adult female Labrador will weigh between 55 and 70lbs. An adult male Lab will weigh 65 80lbs.

Female Lab weight will on average be lower than male Lab weight, but there is a considerable overlap with many larger females weighing more than some males.

Labradors also come in a different types, and your Labs type and their parentage, will have an impact upon their ideal weight.

English Lab Weight vs American Lab Weight

Simply giving you Labrador average weights in pounds can be misleading. It doesnt take into account that English and American Labs can be very different in appearance. And that Labradors vary in their body shape and fitness levels.

Built for speed and agility, your American Lab will often weigh less than your friends English Lab, but not always! English Labs, bred from show lines, are often at the upper end of the scale. You can expect English Lab weight to be around 60 70 lbs for a female and 70 80 lbs for a male.

Some of our chunkier, show bred Labs can be big! Up to twenty pounds heavier than their field bred cousins, without necessarily being overweight. Whereas the slimmer, working American Lab will often be at the lower end of average.

Of course, its not just build that we need to consider, there are many factors that determine the right weight for an individual dog. Labs in great physical condition will weigh more than they did before the reached that condition. Lets look at why that is.

How Much Does A Labrador Weigh When in Peak Condition?

Volume for volume, muscle weighs more than fat yet takes up less space inside your dog. As a dog gains muscle through exercise and activity, their weight will increase.

So a fit dog will have more muscle and weigh maybe ten or fifteen pounds more than an unfit dog of similar dimensions or with a similar frame.

What with the different types of Lab (American /English) and the different fitness levels of different dogs, you can see how difficult it can be to give a rule of thumb on adult Labrador weight. And why unless a dog is grossly obese, or desperately thin, the scales may not reflect your dogs state of health at all.

Coat Color vs Weight

In theory there should be no difference in weight between Labradors of different colors. But in practice there can be some, especially in the colors that are predominantly from either show/English or working/American lines.

Black Lab Weight

Weight for an English black Lab will probably be at the higher end of the range, for an American black Lab it will likely be lower. Black Labs are frequently found in both these categories.

Chocolate Lab Weight

Chocolate Labs are more likely to be show bred than field bred. And because English Labs weigh more than American Labs in general, our chocolate friends may therefore be at the higher end of average when it comes to weight.

Yellow Lab Weight

Your yellow Labs are commonly found in both categories, so have a wide range of weights along with varying coat shades.

White Labs are more likely to be English Labs, and will probably be heavier. Fox red Labs are normally American Labs, and therefore may be lighter in build than the paler yellow Labs that are more popular in the show ring.

So if the scales are not going to help you, how can you figure out whether or not your Lab is a healthy weight?

Labrador Ideal Weight: Does Your Lab Pass The Test!

The way to effectively judge whether your Lab is at an ideal weight is not through the scales. It is by feel and appearance. Your dog should have a waist. You should not be able to see ribs, but if you press firmly along his sides you should just be able to feel your fingers bumping along them.

This Lab really needs to shed a few pounds

Lab Puppy Weight: How Often To Weigh Your Pup

To an extent, this information applies to puppies as well as adults. People often worry about their puppys weight, but in most cases it really is not necessary to weigh your puppy regularly! Any more than you would weigh your three year old child on a daily or weekly basis. There are however, some exceptions.

Very thin puppies

Occasionally our readers have puppies around three weeks old, failing to thrive because they were sold before they were ready to leave their mothers. The only action here is urgent veterinary treatment.

Most puppies sold after eight weeks fall into a healthy weight range. As a very rough guide, many Labrador puppies will weigh around a kilo for every week of their lives. So you would expect a ten week puppy to weigh around ten kilos or twenty-two pounds.

A twenty percent variation around this would be fairly normal. If your puppy falls outside this variation he may still be perfectly healthy, but a veterinary checkup will put your mind at rest.

Should I Weigh My Dog?

The main reasons to weigh a dog are weight loss or gain. Thin puppies need regular weigh-ins to ensure they are gaining weight. Overweight adult Labs need weekly weighings, along with visual checks, to ensure you stay on track with their diet.

Your veterinarian may also need to weigh your dog to give an accurate dose of drugs if he needs medical treatment.

How to weigh a dog

You can weigh a puppy in your arms at home with the bathroom scales by subtracting your own weight. Tiny dogs can be weighed on kitchen scales, or by using fishing scales to weigh a puppy placed carefully in a shoulder bag (weigh the bag first and subtract its weight from your total).

Larger dogs will need to be weighed on purpose built scales. Most vet surgeries have one in the waiting room, and some pet stores have them too.

How Much Should My Labrador Weigh?

Appearances count more than numbers. Look at your dog objectively, and avoid comparing with other dogs weight.

Some other dog owners will tell you your slim Labrador is too thin. This is because people are getting used to so many dogs being overweight, including some of those receiving the highest accolades in our show rings. If you are worried, check with your vet, but the chances are your dog is healthy, and it is reallytheir dog who is overweight.

Fat Labrador

Its not unusual to see a fat Labrador. Our perspectives on healthy weights for dogs have been a little skewed in recent years as more pets hit the obesity marker on the scale. And Labradors are very prone to weight gain for genetic and hunger reasons!

Canine obesitycomes with a raft of accompanying health problems. Feeding your Labrador just the right amount can be a bit of a balancing act, but its one that you have a responsibility to try your best to achieve. Not all Labradors need the same amount of food, so you will need to pay attention to your individual dogs needs, and be prepared to change your habits if necessary.

Some dogslikeworking dogs for example, will need quite a lot more food in the winter than they do in the summer. This is down to the amount of exercise he is getting differing dramatically in the changing seasons. You need to adapt your feeding to suit these shifts.

IsMy Labrador Fat?

It is really important that you keep your Labradors weight appropriate for his height and build, rather than following guidelines on food packets or in books too closely. The best way to tell is by eye and touch.

Have a look at your dog and compare him with the picture below of a healthy Labrador. Look at your dog from the side.

Does his belly slope upwards towards his groin, or is it a level line from his front legs to his back, or even worse is it sagging down between his legs?
Your Labrador should have an upward sloping line from the base of his chest, towards his back legs.
Now look at the dog from above. Can you see a waist just in front of his hips? You should be able to! Your dog should not be the same width all the way down his body.
Look at your dog from the side again. Can you see any ribs?
You should not be able to see a labs ribs whilst he is standing still though you may well be able to see the last one or two when he is eating, drinking or bending and twisting.
Run you hands along his rib cages firmly. Can you feel his ribs?

Ideally you should be able to just feel, but not see, your dogs ribs. If you can see ribs when he is standing still he is too thin. If you cannot feel his ribs at all with your hands he is too fat!

How Much Should My Labrador Weigh?

As we have seen above, the best way to tell if you have a fat Labrador is by looking and feeling. The trouble with providing you with a number is that it can give a false impression.

Depending upon whether your Lab is field or bench bred, short or tall, chunky or slight, male or female, will all make a big difference to their ideal weight for the individual.

The average adult Labrador will weigh anywhere between 55 to 80 lbs! Male Labs usually being around 5 to 10 lbs heavier than their female counterparts.

If you are still unsure whether your Lab is the right weight for his or her build having given her a thorough check yourself as described above, then the best thing to do is to pop down to your local veterinarian.

They will be happy to let you know how much your individual Labrador should weigh.

Why Is My Labrador Fat?

So how did your slim little puppy end up as a fat adult Labrador?

There are threecommonassumptions that people make when considering how theirdogs came to beoverweight.

Does the dog need more exercise? Has he got some kind of medical problem? Or am I just feeding him too much at mealtimes or giving too many snacks?

In general if your dog is overweight the real reason is simply that he has eaten too much. Or rather, been allowed to eat too much.

So lets have a look at how we can eliminate these other possibilities where most dogs are concerned.

Does my dog need more exercise?

People often say to me, my Lab is a bit overweight because he hasnt had much exercise lately.

Whilst exercise can help to keep your dog in shape as a part of their daily routine, it is not the critical factor when it comes to putting on weight.

He may well need more exercise, but that is not why he is fat.

He is overweight because when you take into account the amount he exercises along with a number of other factors, he has eaten too much.

The exercise needs of your dog are an important but separate issue, whichwe look at in other articles. The important thing to remember is this:

The less exercise you give the dog, the less you must feed him.

You cant be forever playing catch up with his weight, or hoping to spend more time walking him next week. Once put on, weight is hard to shift and it will simply go up and up over time.

You need to control it on a regular weekly/monthly basis, starting now.

Medical causes of canine obesity

Although most dogs who are overweight have simply had a few too many bites to eat, there are some medical causes for obesity which do crop up from time to time.

Canine medical conditions that can affect your Labs weight include hypothyroidism, insulinoma and hyperadrenocorticism.

If a medical condition is the reason then the weight gain will normally be sudden and unexpected.

If you are concerned by sudden weight gain in your Lab when you have not been giving him more food, then a checkup at the vets is definitely in order.

You may also find that your dog puts on weight after having been neutered. If this is the case you will need to adjust your feeding habitsaccordingly.

However, for most dogs weight gain is a simple result of over feeding.

My Labrador is always hungry

People are often concerned because they worry that their dog is still hungry after eating his dinner. Here is an important truth:

Most Labradors are always hungry.

You cannot win this battle. These are greedy dogs and your Labrador will always want more food than you give him. No matter how much that may be.

If your Labrador is overweight he really needs to eat less and he will get used to his new regime quite quickly.

Are Fat Labs Less Healthy?

If you have looked at your Labrador and decided he is overweight, you might be wondered whether that actually matters.

You still love him and he doesnt care what he looks like so why should you bother?

Is it really worth the effort of ignoring those puppy dog eyes and whines for extra food? Arent chubby Labs just even more cute and cuddly than their skinny friends?

Whilst its true that your dog has no interest in his outward appearance, he will be the one suffering on the inside if you allow him to get fat.

Slim dogsare healthier

Being overweight predisposes you to an awful lot of unpleasant health problems. This is true regardless of whether you are a human or a dog.

Carrying extra pounds can also make existing problems your dog may have worse. For example joint problems like arthritis and hip dysplasia can beexacerbated by having more weight to lug around.

As well as joints and bones suffering from obesity related issues, increased body fat can also make your dog more likely to have problems with their organs including those needed for breathing and digestion.

Scarily, in order for these risks to be increased your dog doesnt even have to be very over weight. Just a bit of extra fat can havea host of unwanted consequences.

Being a fat Lab puppy can potentially make your dog more likely to suffer from joint problems later in life.

Slim dogs live longer

Not only will a slim dog have a better level of fitness and a lower likelihood of becoming unwell, they will in all probability live longer too.

Purina PetCare carried out a lifetime study on 48 Labradors, where they were divided into two categories, one of which was given 25% more food than the other.

Those Labs on the largefood ration had a median lifespan of over 11 years old. Those on the smaller food ration lived to be over 13 years old.

When you look at the difference which can be made in these terms, by helping your Lab to stay slim you could be giving him an incredible two more years with you!

So, if you are going to help your Lab to lose weight lets have a look at the best way to go about it.

How to Reduce your Dogs Food

The first thing to cut out of your overweight dogs diet is any snacks or fillers that you give him in between meals. If he gets a lot of household scraps these may have to go too.

If you use food as rewards in dog training,this should be deducted from his daily food allowance.

It could also help to find healthier alternatives to your usual training treats.

Bear in mind that if your dog is unwell, old or very young, it is sensible to consult your vet before tampering with his diet. It is also a good idea to have a chat with them beforehand if your dog is very overweight and has a lot to lose.

Record your Dogs Weight Loss Progress

If your dog gets nothing to eat but a complete dog food then you can safely simply reduce the quantity you give him by about a third for three to four days.

Take a photo of him from above and from the side before you start.

At the end of the three to four days, check the dog over as described above and ask yourself if he is still fat.

(paid link)

If you think he has improved a little but needs to slim down a bit further, keep going for another three to four days then review the situation.

Compare the photo you took a week ago and you should see some improvement.

Keep going until your dog has a waist again and you can feel his ribcage when you press firmly along his sides.

You may need to increase his food slightly in order to maintain his new slim figure and ensure he does not get thin.

If the dog is not losing weight after a couple of weeks on two-thirds of his previous food allowance, you may need to cut his food down even further.

This is a good point to check in with your vet, let him know what you are doing and get his opinion on cutting down further on the dogs daily food rations.
