Why are Labradors always hungry? The science behind their love of food

If you’ve ever owned a Labrador, you’ll know that food is often one of their greatest loves. Whether they’re patiently waiting beside their empty bowl, following you into the kitchen or giving you those irresistible puppy-dog eyes, Labradors seem to have an endless appetite.

But have you ever wondered why your Labrador always seems hungry, even moments after finishing a meal?

While their enthusiasm for food might seem like another lovable personality trait, research suggests there could be something much more interesting happening beneath the surface.

From genetic differences that influence hunger to the importance of maintaining a healthy weight, understanding your Labrador’s appetite can help you make better decisions about their health and wellbeing.

Why do Labradors love food so much?

Labradors are well known for their friendly personalities, intelligence and eagerness to please. They’re also famous for being incredibly food-motivated.

For many Labradors, the possibility of a treat is enough to capture their attention instantly. This enthusiasm can make them wonderful training companions, but it can also make managing their food intake a little challenging.

Like other dogs, Labradors learn to associate food with rewarding experiences. A treat after following a command, dinner arriving at the same time each evening or an occasional snack from the family can all reinforce food-seeking behaviours.

However, research has shown that some Labradors may have a biological reason for being particularly interested in food.

And it all comes down to their genetics.

The science behind the Labrador hunger gene

Scientists at the University of Cambridge have discovered that some Labradors carry a genetic mutation associated with increased hunger and a greater risk of obesity.

The mutation affects a gene called POMC (pro-opiomelanocortin), which plays an important role in regulating appetite and energy use.

Normally, the POMC gene helps the body produce chemical messengers involved in controlling hunger and metabolism.

However, in Labradors carrying a particular mutation, some of these signals are disrupted.

According to research published by the University of Cambridge in 2024, approximately 25% of Labradors carry this genetic mutation.

The researchers found two particularly interesting effects:

• Increased hunger: Affected dogs may become hungry again more quickly between meals, even after eating enough food.
• Lower energy expenditure: Dogs carrying the mutation were found to use approximately 25% less energy at rest than dogs without it.

This means some Labradors may naturally want to eat more food while requiring fewer calories to maintain a healthy weight.

It’s an important finding that helps explain why managing portions and maintaining a healthy weight can be particularly challenging for certain Labradors.

Of course, not every Labrador carries this mutation, and genetics are only one part of the picture. Feeding habits, exercise, age and individual metabolism can also influence a dog’s appetite and weight.

Do Labradors actually feel hungry all the time?

If your Labrador looks at you as though they haven’t eaten in days, you might wonder whether they’re genuinely hungry or simply hoping for another snack.

Interestingly, the answer could be a little of both.

Researchers found that Labradors carrying the POMC mutation do not necessarily need larger meals to feel full. Instead, they appear to experience greater hunger between meals.

In one experiment, scientists placed a sausage inside a clear container that dogs could see and smell but couldn’t access.

Labradors carrying the mutation showed greater persistence in trying to reach the food compared with dogs without the mutation.

The findings suggest that some Labradors may experience stronger biological signals encouraging them to seek food, even when their nutritional needs have already been met.

However, hunger isn’t the only reason dogs beg for food.

Your Labrador might also seek food because:

• They’ve learned that begging sometimes results in a treat.
• They’re bored and looking for stimulation.
• They associate food with attention and positive experiences.
• They enjoy the taste, smell and excitement of eating.
• They’ve developed a routine around particular feeding times.

Understanding these behaviours can help you respond to your dog’s needs without automatically reaching for another snack.

Why Labradors can be prone to weight gain

When a dog loves food as much as a Labrador, it’s easy for a few extra treats to become part of their daily routine.

But those additional calories can add up over time, particularly if your Labrador is less active or has a naturally lower energy requirement.

Being overweight can place additional strain on a dog’s body and contribute to a range of health concerns.

Joint problems and arthritis

Excess body weight increases the load placed on joints, potentially worsening discomfort and mobility problems.

For Labradors, which can be susceptible to conditions such as hip and elbow dysplasia, maintaining a healthy weight is particularly important.

Reduced mobility and exercise tolerance

Carrying additional weight can make everyday activities more challenging.

Walks, swimming and playing fetch may become more tiring, which can make it harder for an overweight dog to remain active.

Metabolic and other health concerns

Obesity can contribute to wider health complications, including changes in metabolism and an increased risk of certain medical conditions.

Maintaining a suitable weight throughout your Labrador’s life can support their comfort, mobility and overall wellbeing.

The encouraging news is that, even for Labradors with a genetic tendency towards weight gain, appropriate nutrition, portion control and regular activity can make a meaningful difference.

How to tell if your Labrador is a healthy weight

Because Labradors naturally have a sturdy build, it isn’t always easy to recognise when they’re carrying a little extra weight.

Rather than relying on the scales alone, veterinarians often assess a dog’s body condition score.

This considers how easily you can feel certain parts of their body and how their overall shape looks.

According to the World Small Animal Veterinary Association (WSAVA), body condition scoring is a useful tool for assessing whether a dog is underweight, overweight or in an ideal condition.

Some signs of a healthy body condition include:

• Ribs: You should be able to feel your Labrador’s ribs without pressing firmly, with a light covering of fat.
• Waist: Looking down from above, your dog should have a visible waist behind their ribs.
• Abdominal tuck: From the side, their abdomen should rise slightly towards their hind legs.
• Movement: Your Labrador should generally be able to participate comfortably in age-appropriate activities.

Every dog is different, so your veterinarian is the best person to help determine your Labrador’s ideal weight and body condition.

How to manage your Labrador’s appetite

Having a Labrador who loves food doesn’t mean you need to eliminate treats or make mealtimes less enjoyable.

Instead, a few practical changes can help make feeding more manageable while keeping your dog happy and stimulated.

1. Measure their daily food portions

Rather than estimating how much food goes into their bowl, measure or weigh their meals according to an appropriate feeding plan.

Feeding guides on dog food packaging can provide a starting point, but your Labrador’s actual requirements will depend on their weight, age, activity level and individual metabolism.

Your veterinarian can help determine a suitable daily calorie allowance.

2. Be mindful of treats

Treats are fantastic for training and rewarding good behaviour, but they should form only a small part of your Labrador’s daily diet.

The WSAVA recommends that treats make up no more than 10% of a dog’s daily calorie intake.

Try setting aside a portion of your Labrador’s regular food to use as training rewards rather than continuously adding extra snacks.

3. Try slow feeders and puzzle toys

Some Labradors finish their meals so quickly that it feels like their bowl was full only seconds ago.

Slow-feeding bowls, puzzle feeders and food-dispensing toys can make mealtimes more engaging.

These options encourage your dog to work for their food, providing mental stimulation while slowing down the eating process.

4. Keep them physically active

Labradors are generally energetic dogs that enjoy activities such as walking, swimming, retrieving and interactive play.

Regular exercise helps support healthy weight management while providing valuable mental and physical enrichment.

However, exercise should always suit your dog’s age, fitness and physical condition.

If your Labrador is overweight or has existing joint issues, speak with your veterinarian before significantly increasing their activity.

5. Establish a consistent feeding routine

Feeding your Labrador at predictable times can make it easier to manage their daily food allowance.

Some dogs may also benefit from having their food divided into smaller meals throughout the day, provided the total daily calories remain appropriate.

Try to avoid rewarding persistent begging with extra food, as this can reinforce the behaviour.

6. Use attention and play as rewards

Not every reward needs to be edible.

A favourite toy, game of fetch, affectionate attention or short training session can all provide positive experiences without adding extra calories.

For food-loving Labradors, finding a balance between edible treats and other rewards can be particularly helpful.

When should you speak to a vet about your Labrador’s hunger?

Although a strong appetite is common in Labradors, a sudden or unusual increase in hunger shouldn’t automatically be dismissed as typical breed behaviour.

In some cases, changes in appetite may be associated with an underlying medical condition.

According to VCA Animal Hospitals, increased appetite can sometimes occur alongside conditions such as diabetes mellitus, Cushing’s disease or disorders affecting nutrient absorption.

It’s worth arranging a veterinary appointment if you notice:

• A sudden or significant increase in your dog’s appetite.
• Unexplained weight loss despite eating more.
• Increased thirst or urination.
• Persistent vomiting or diarrhoea.
• Changes in energy levels or behaviour.
• Rapid weight gain or difficulty maintaining a healthy weight.

Your veterinarian can assess your Labrador’s symptoms, review their diet and recommend any necessary investigations.

Even if your Labrador appears healthy, routine veterinary appointments are a valuable opportunity to discuss weight management and nutritional needs.

Keeping your food-loving Labrador healthy

There’s something wonderfully endearing about a Labrador’s enthusiasm for food.

Whether they’re waiting patiently for dinner or enthusiastically performing every trick they know in exchange for a treat, their love of eating is often part of what makes them such entertaining companions.

But understanding the science behind their appetite can help owners recognise that hunger and food-seeking behaviour aren’t always simply habits.

For some Labradors, genetics may genuinely influence how hungry they feel and how efficiently their bodies use energy.

By maintaining appropriate portions, providing regular exercise, monitoring their weight and seeking veterinary advice when needed, you can help your Labrador enjoy a happy, active and healthy life.

And while you can’t always predict when health concerns might arise, being prepared for unexpected veterinary expenses is another way to look after your four-legged family member.
