Feeding a Labrador: Diet, Weight and Portion Guide for UK Owners

Labradors are one of the UK's most beloved breeds — and one of the most food-motivated. Their seemingly insatiable appetite is not just personality; research has identified a genetic mutation in the POMC gene that affects how Labradors sense fullness, making them genuinely more likely to overeat than many other breeds. Understanding this helps UK Lab owners make smarter feeding decisions.

Why Labradors Are Prone to Obesity

In 2016, Cambridge University researchers identified a deletion in the POMC (pro-opiomelanocortin) gene that is common in Labradors and flat-coated retrievers. Dogs with this mutation produce less of a hormone that signals satiety — meaning they feel less full after eating and remain hungry more persistently than other breeds.

Researchers found this mutation in approximately 25% of Labradors studied, and it is even more prevalent in Labradors trained as guide dogs or assistance dogs — likely because the food motivation associated with the mutation makes them easier to train with reward-based methods.

The practical implication for UK Lab owners is that following a Labrador's apparent appetite is a reliable way to overfeed them. Unlike some breeds that self-regulate intake, many Labradors will eat far beyond their energy needs if given the chance.

Health Consequences of Obesity in Labradors

Obesity in Labradors is not just an aesthetic issue — it has direct, serious health consequences. Excess weight dramatically worsens hip and elbow dysplasia, which are already extremely common in the breed. Every additional kilogram of body weight places multiple kilograms of force across arthritic joints during normal movement.

Obese Labradors develop osteoarthritis earlier and more severely than those maintained at a healthy weight. Studies have found that Labs maintained at their ideal body weight live significantly longer and have a notably lower rate of orthopaedic problems than overweight dogs of the same breed.

Additional health risks associated with obesity in Labradors include increased risk of diabetes, reduced respiratory efficiency, a higher anaesthetic risk during any procedure, increased strain on the heart and reduced immune function. Maintaining healthy weight is arguably the single most impactful thing a Lab owner can do for their dog's long-term health.

How Much to Feed a Labrador

An average adult Labrador (25–35kg, moderately active) requires approximately 1,200–1,800 kcal per day. However, there is considerable variation based on age, activity level, whether the dog is neutered, and individual metabolism. Neutered dogs generally need 20–30% fewer calories than intact dogs of the same size.

Always start with the manufacturer's feeding guide based on your dog's ideal body weight — not their current weight if they are already overweight. Weigh food using kitchen scales rather than estimating by eye or using cups. Small differences in portion size compound over months and years.

Divide daily food into two meals rather than one, as this is easier on digestion and may help with satiety. Never leave food down for free-feeding — Labradors will typically eat continuously if food is available.

Assessing Your Labrador's Body Condition

The body condition score (BCS) system, used by UK vets, rates dogs on a scale of 1 (emaciated) to 9 (severely obese), with 4–5 being ideal. At an ideal weight, your Labrador should have: ribs that are easy to feel with gentle pressure but not visually prominent; a visible waist when viewed from above; a slightly tucked abdomen when viewed from the side.

Many UK Lab owners are accustomed to seeing overweight dogs and may perceive a dog at ideal weight as too thin. The PDSA and Dogs Trust both produce BCS guides that are freely available and worth bookmarking.

If your Labrador is overweight, weight loss should be gradual — approximately 1–2% of body weight per week. Crash diets can cause muscle loss and may stress the liver. Your vet can create a weight loss programme using a prescription calorie-controlled diet if your dog has significant weight to lose.

Best Foods for Labradors

Labradors do well on high-quality complete diets that are moderate in fat and provide adequate protein for muscle maintenance. Avoid very high-fat diets or high-calorie senior foods for Labs that are already prone to weight gain. Large-breed specific adult formulas tend to suit Labradors well.

For overweight Labs, weight management prescription diets (such as Royal Canin Satiety or Hills Metabolic) are more effective than standard 'light' pet shop foods, as they are better satiety-adjusted and clinically tested. These typically cost £50–£80 per month for a large dog.

Treats should account for no more than 10% of daily calories. Carrot sticks, cucumber and apple slices (no seeds) make excellent low-calorie training rewards for food-motivated Labs without adding significant calories.

Find a Vet Near You

Regular weight checks are important for Labradors throughout their life. Many UK vet practices offer free nurse weight clinics between full consultations. If you are concerned about your Labrador's weight, book an appointment to discuss a weight management plan.
