Feeding guides provide a starting point. Use your dog’s weight, body and muscle condition, activity, life stage and health with veterinary advice to set and review portions.
I am not a vet. This is the method I use, and the two-minute check that replaced my guessing.
Body condition beats the feeding guide
Feeding guides are a starting point and nothing more. Two dogs of the same weight can need meaningfully different amounts, and a neutered dog often needs less than the bag suggests.
Use your hands weekly instead. Run them along the ribs: you want to feel them easily under a thin layer of covering, the way you feel the knuckles on the back of your hand. Look from above for a waist behind the ribs. Look from the side for a tuck up toward the back legs.
Learn body-condition assessment from your veterinary team and track weight as well as shape. Agree the portion and recheck interval with them; do not automatically wait a month or cut food because a rib check seems different.
Why this matters more than it sounds
Extra weight is not cosmetic. The AVMA states that “Obesity in senior pets is linked to an increased risk of arthritis, difficulty breathing, insulin resistance or diabetes, heart disease, high blood pressure, skin problems, cancer, and other conditions.”
The loop is the problem. A heavier dog moves less because moving is less comfortable, and moving less puts on more weight. It closes quietly over a year or two and gets experienced as a dog slowing down with age.
Catching it early is far easier than reversing it, which is the whole argument for the weekly hands-on check.
A workable feeding day
Times matter less than consistency. Pick times you can keep on a bad week.
| When | What | Why |
|---|---|---|
| Morning | Part of the agreed daily allowance | Use the meal schedule that fits the dog’s age, health and medication plan |
| During the day | Record treats and other food in the calorie total | Use suitable rewards without displacing balanced nutrition |
| Evening | The other half, ideally from a mat or puzzle | Working for food settles a restless dog |
| Around exercise | Ask your vet about a safe routine for the individual dog | Do not use a fixed feeding delay as a guarantee against bloat |
| Weekly | Hands on the ribs, same day each week | You will not notice gradual change any other way |
| Review interval | Follow the plan agreed with your veterinary team | Report appetite, illness or unexpected weight changes promptly |
How often to feed
Two meals a day suits most adult dogs. Puppies need more frequent, smaller meals, and the schedule changes as they grow, which is a question for your vet about your particular puppy.
Set mealtimes can make intake easier to monitor. If a healthy dog grazes on an agreed plan, measure the daily food and record leftovers. A change in appetite still needs attention; grazing does not make observation impossible.
For large, deep-chested breeds, splitting into two or three smaller meals rather than one large one is the common advice, alongside not feeding immediately around hard exercise. Our article on feeding problems worth watching for covers bloat, which is the reason.
Measure with something consistent. A mug from the cupboard is not a measure, and the difference between a heaped and a level scoop can be a meaningful share of a small dog’s day. Use the scoop the manufacturer specifies, a proper measuring cup, or kitchen scales, which are the most accurate of the three.
Scales matter most for small dogs, where a modest error is a large proportion of the daily total. For a five-kilo dog, being generous twice a day adds up to a real weight change across a few months.
Count the treats, honestly
This is where most portioning falls apart. Training treats, dental chews, the crust from a child’s toast, a lick of yoghurt, and whatever the neighbour hands over the fence.
The FDA makes the nutritional half of the point: treats and supplements “are typically not intended to be a pet’s sole diet, so these products are often not complete and balanced.” Feed enough of them alongside a complete food and the overall diet stops being complete.
The fix is arithmetic, not willpower. Measure the daily ration into a container each morning and take training rewards from it. When the container is empty, the day is done.
Getting portions right
- Start from the bag’s guide, then adjust to the dog
- Measure with a proper cup or scales, not by eye
- Portion the whole day out in the morning, treats included
- Two meals at fixed times for most adult dogs
- Hands on the ribs weekly, the same day each week
- Agree changes and a monitoring interval with your vet
- Re-check the portion whenever you change food, since calorie density differs
When the amount needs to change
After neutering, many dogs need less. After a change in activity, in either direction. In winter for some dogs and summer for others. As a dog reaches middle age and slows down. And every time you switch foods, because a cup of one food is not a cup of another.
when and how to switch dog foods covers a planned transition for a well dog. Review calories whenever food changes and agree the monitoring interval with your vet; do not wait a month if symptoms or an unexpected weight change appear.
Contact your vet promptly about appetite loss, eating pain, unusual thirst or an unexpected weight change. Seek advice before changing food amounts for a diagnosed condition or a weight-loss plan.
- Is losing weight without you reducing food
- Is gaining despite a sensible portion
- Is suddenly ravenous, or has gone off food entirely
- Is drinking noticeably more than usual
- Has a condition affecting diet: kidney disease, pancreatitis, diabetes
A weight loss plan is worth doing with your vet rather than by eye, because cutting food hard causes its own problems. Ask them to show you how to assess body condition on your own dog once, in person. It takes two minutes and you will use it weekly for years.
What good looks like
Ribs easy to feel, a visible waist, steady weight month to month, and a dog who eats his meals within a reasonable window without negotiation.
Not an empty bowl in ten seconds, and not a dog who has to be coaxed. Both of those are worth looking at, and our article on fixing a picky eater covers the second.
Do the check tonight. Hands on the ribs, and be honest about what you feel.

Measuring by weight can make portions more consistent. A digital kitchen scale is one commercial option; use the food’s calorie information and the feeding plan rather than relying on a scoop’s appearance.
Questions people ask
How much food should I feed my dog each day?
Start with the package guide and ask your vet how it fits your dog’s life stage, health, weight and body condition. Measure the allowance and record intake. Agree changes and rechecks with the veterinary team rather than using a universal one-month wait.
Should I feed my dog once or twice a day?
Most adult dogs do well with two meals a day at set times. Puppies need smaller meals more often, and their schedule changes as they grow, so ask your vet what fits your puppy’s age and needs. For a large, deep-chested dog, discuss meal size and exercise timing with your vet, since one large meal may raise concern about bloat.
Do dog treats count as part of the day’s food portion?
Set aside your dog’s full ration each morning and take training rewards from that amount. Include dental chews, table scraps, and other extras in the day’s total. Treats are often not complete and balanced, so too many can crowd out the food meant to provide full nutrition. Once the set-aside food is gone, avoid adding more rewards from the bag.
How can I tell if my dog’s food portion is right?
You should be able to feel the ribs without pressing hard, with a thin layer over them. From above, look for a waist behind the ribs. From the side, look for an upward tuck near the back legs. Check on the same day each week. If the ribs feel sharp or stay hard to find after portion changes, ask your vet to assess your dog’s body condition.
What should I do if my dog stops eating?
Set mealtimes help you spot a change in appetite. Watch whether your dog keeps refusing food, drinks more than usual, or gains or loses weight without a clear portion change. If your dog has gone off food, or you notice those changes, call your vet instead of making more food adjustments on your own.
