A Labrador's appetite is the worst measuring tool you own
A Labrador Retriever is being overfed when his body condition changes, and his behaviour at the bowl will never tell you so. Labradors are renowned among vets and trainers for an unusually persistent food drive: many will finish a full meal and immediately forage, beg, and raid bins as though nothing arrived. Some of that drive is simply the breed's working heritage as a tireless retriever who needed fuel and motivation close at hand. Treat his enthusiasm as personality, not data. The data lives in three places you can check in a minute: his ribs, his waist, and the base of his tail.
The tail base gives an overfed Labrador away
The thickened base of the tail is one of the earliest places an overfed Labrador Retriever stores surplus. A Labrador's tail should taper from a sturdy root, but when fat pads build up, the root becomes as wide as the hips and the whole rear outline looks blocky and straight from spine to tail tip. Run your hand over his ribs at the same time: on a Labrador at a sound weight you can feel each rib under a thin, mobile layer, the way you feel knuckles under a glove. If you have to press firmly to find them, or the skin over the ribs feels still and doughy, his ration has been outrunning his exercise.
The waist check works even on a barrel-chested breed
An overfed Labrador Retriever loses his waist even though the breed is naturally deep and broad through the chest. Viewed from above, a fit Labrador narrows visibly behind the ribs; an overfed one runs the same width from shoulders to hips, like a loaf. Viewed from the side, his underline should tuck up behind the deep chest instead of levelling out into a straight belly line. Do this check with him standing, not sprawled, and repeat it on the same day each month so coat, posture, and your own optimism stay constant. Photographs from above, taken in the same doorway light, make slow change obvious.
Count what a Labrador actually eats in a day
The daily total, not the scoop size, is what overfeeds most Labrador Retrievers. This breed is a professional opportunist: food dropped by toddlers, cat food found behind a door, training rewards during gundog-style games, and anything edible on a walk route all count toward the day. For one week, write down everything that goes into him, meal and non-meal alike, and have everyone in the household contribute honestly. Then look at where the surplus sits. Usually the set meals are defensible and the grazing is not. Fix the grazing first with lids, closed doors, and a household agreement that the Labrador's pleading face changes nothing, and only then trim the measured meals slightly.
When a Labrador's weight gain deserves a vet visit
Contact your veterinarian if your Labrador Retriever gains weight on a ration you have genuinely audited, if he becomes reluctant on stairs or shorter walks, or if heavier breathing, heavier drinking, or a duller coat arrives with the gain. A vet can confirm his condition score on an accurate scale, check whether something besides food is contributing, and help you set a sensible target and pace for bringing him down. Arrive with his food log and weigh-in history rather than a guess, because the pattern over time is exactly what the vet needs to see. Storing that history in KinsLe's Pet Passport keeps his weights, visit notes, and feeding records together in one packet, ready to pull up at the clinic or hand to a boarding kennel without digging through old messages.
