How Much Should a Dog Eat Each Day?

If you have ever looked at the back of a bag of dog food and wondered whether that amount could possibly be right, you were asking a fair question. Those figures are calculated for an averagely active, unneutered adult dog of a given weight, and almost no individual dog matches that description.

Treat the bag as a starting point rather than an instruction, and adjust from there. Here is how to do that properly.

Start with the packet, then adjust

Find your dog's weight on the chart and feed that amount, split across meals. Then adjust every couple of weeks based on the dog rather than the chart.

Feed to the dog's ideal weight, not its current one. An overweight dog fed for what it currently weighs stays overweight.

What shifts the number

• Neutering lowers energy requirements noticeably. Continuing to feed the same amount afterwards is the most common cause of gradual weight gain.
• Age. Puppies need far more per kilo than adults. Older dogs generally need less, though some elderly dogs lose weight and need more.
• Activity. A working or genuinely exercised dog may need considerably more than a dog that walks twice a day.
• Weather. Dogs use less energy maintaining body temperature in warm weather.
• Illness, pregnancy and nursing all change requirements substantially and should be guided by a vet.

Measure it

Use an actual measuring cup or a kitchen scale. Portions judged by eye drift upward over months without anybody noticing, and the drift is invisible until the dog is a size larger.

Weighing is more accurate than volume, because kibble density varies between brands. If you change brand, re-check the amount rather than assuming the same scoop applies.

How often

• Adults: twice a day suits most dogs
• Puppies: three or four meals depending on age
• Deep-chested large breeds: two or three smaller meals rather than one large one, and avoid heavy exercise immediately around eating, which is associated with bloat

Avoid leaving food down all day. Beyond weight control, scheduled meals let you notice appetite loss, which is the earliest sign of most illness and the thing free feeding hides.

Treats count

Treats should be a small fraction of daily intake, and most owners underestimate what they give because several people in a household give them independently. If you are working on weight, take treats out of the daily ration rather than adding them on top.

Checking whether you have it right

Once a fortnight, do the same three checks used for body condition:

1. Ribs easy to feel under a thin covering, without pressing hard
2. A waist visible from above, narrowing behind the ribs
3. A tuck from the side, the belly rising toward the hind legs

Adjust by about ten percent at a time and wait two or three weeks before judging. Large swings cause digestive upset and tell you very little.

Mixing home food with commercial food

Common and worth doing carefully. Adding rice and stew to a complete food both unbalances the formulation and adds calories nobody counted. If you feed home-prepared food, either commit to it properly with veterinary guidance on balancing it, or keep it to a small, deliberate share of the ration. The middle ground, where extras arrive unmeasured on top of a full bowl, is where most weight problems begin.

Our free feeding and portion guide is printable and gives you somewhere to record what you actually feed, which is usually more revealing than what you think you feed.

When the amount is not the issue

See a vet if a dog is losing weight on a normal ration, always hungry despite adequate food, gaining despite honest portion control, or has a poor coat and low energy. Worms, thyroid disease, diabetes and malabsorption all mimic feeding problems, and none of them respond to a different scoop size.

Feeding is the one part of pet care owners adjust endlessly on their own, because it feels free to experiment and a consultation does not. The irony is that a single visit where a vet weighs the dog, scores its condition and tells you the number for your animal ends months of guessing.

Those consultations are covered on Skeepy Pet HMO plans, which makes getting the answer cheaper than continuing to guess at it.
