Quick answers

Why are Labs always hungry?

Many Labs carry a POMC gene variant linked to stronger food motivation, and the breed is prone to becoming overweight. Measure meals, count training treats as calories, and keep a visible waist. Extra weight loads the hips, elbows and knees over time. Answer page →

Why it matters

Being lean is the most powerful health intervention you control. In Purina’s lifetime study of 48 Labs, the dogs fed 25% less than their littermates lived a median 1.8 years longer and developed arthritis later (Kealy et al., 2002).

Body condition score (9-point scale, simplified)

Each point above 5 is roughly 10% over ideal weight, a commonly used clinical rule of thumb (WSAVA body condition tools).

A 4-step weight-loss plan

  1. Get a target weight from your vet and rule out medical causes such as hypothyroidism.
  2. Calculate calories for the target weight with our calorie calculator. Weight-loss plans often start near 1.0 × RER for target weight.
  3. Weigh food on a scale. Measuring cups commonly mis-measure kibble.
  4. Re-weigh every 2–4 weeks and adjust by about 5–10%.

Tactics that work for hungry Labs

  • Swap a portion of kibble for green beans (ask your vet first)
  • Use puzzle feeders and snuffle mats to make meals last
  • Count treats and use part of the daily kibble as training rewards
  • Pre-portioned fresh food (for example The Farmer’s Dog or Ollie) takes the guesswork out of portions for some owners
  • A vet-prescribed weight-loss diet is the most evidence-backed option for dogs that need to lose a lot

The genetic angle

About a quarter of Labs in the Cambridge study carried a POMC deletion associated with higher food motivation (Raffan et al., 2016). If your Lab acts starving on a correct diet, you’re not imagining it. Stick to measured portions and enrichment, not extra food.

Chews are a common hidden calorie source. Our chews and bones guide flags which are calorie-dense, and non-food toys give the same enrichment with zero calories.

Frequently asked questions

How fast should a Lab lose weight?

Vets commonly target about 1–2% of body weight per week. Faster than that risks muscle loss, so set the plan with your vet.

Why is my Lab always hungry?

Some Labs carry a POMC gene deletion linked to greater food motivation and higher body weight. Bulky, low-calorie food, puzzle feeders and measured meals help.
