Vet's advice

How Much Should a Dog Eat Per Day?

It's one of the most frequent — and most underestimated — questions for anyone living with a dog. Give too little and it's left unsatisfied and lacking; give too much and, year after year, you lead it straight to being overweight. We asked a vet how to work out the right portion, how many times a day to feed a dog and why the correct amount changes from animal to animal.

There's no single figure that's right for all dogs: the amount of food depends on a series of factors that need to be considered together. A 3 kg Chihuahua and a 35 kg German Shepherd have completely different needs, just as a growing puppy and a calm elderly dog do. In this guide we'll look at what the daily ration depends on, how many times a dog should eat at different stages of life, and you'll find an indicative chart of amounts by weight band. Treat these figures as a starting point: the precise amount should always be fine-tuned for the individual animal.

What the right amount depends on

The correct ration isn't decided by eye: it's calculated from the dog's energy needs, which change depending on several factors. The main ones are:

• Weight and size. It's the starting point. The bigger the dog, the more it eats in absolute terms — but, in proportion to weight, small dogs have a faster metabolism and burn relatively more per kilo.
• Age. A growing puppy needs much more energy than an adult; an elderly dog, usually less active, tends to need less and to put on weight more easily.
• Activity level. A dog that runs, works or takes long walks burns far more than a sedentary dog living in an apartment. Two dogs of the same weight can have needs that differ by 20-30% for this reason alone.
• Neutering. After neutering the metabolism slows and calorie needs fall, often by 10-20%. It's one of the reasons many dogs gain weight after the procedure: the portion should be reduced accordingly.
• Physical condition. A dog that's already overweight shouldn't be fed based on the weight it has, but on the ideal weight it needs to return to. A dog that's too thin, by contrast, needs support.

To tell whether the amount is right, the best indicator isn't the scale but the dog's body: you should be able to feel the ribs under a thin covering of fat, without seeing them stand out, and notice a clear "waist" when looking from above. If the ribs disappear under a soft layer, you're giving too much.

How many times a day should a dog eat

The number of meals is almost as important as the amount. Spreading the food well across the day aids digestion and keeps the dog's energy more stable.

• Puppy: 3-4 meals a day up to 4-6 months, then gradually moving to two. A small stomach and high needs make frequent, regular meals necessary.
• Adult dog: two meals a day, morning and evening, are the ideal standard. A single daily meal is not recommended because it means very large portions all at once, harder to digest and — especially in large, deep-chested breeds — associated with a higher risk of gastric torsion (bloat).
• Elderly dog: two meals are kept; if anything, more attention is paid to digestibility and the amount is adjusted to the drop in activity.

Whatever the frequency, the total daily amount doesn't change: you simply divide the day's needs by the number of planned meals. Having regular times also makes house-training and toilet management easier.

Indicative chart of amounts by weight

Here's a reference chart with the indicative daily amounts for an adult dog, of normal build and moderately active, broken down by weight band and by type of food. The values should be divided across the day's meals (usually two) and are purely indicative: calorie density varies a great deal from product to product, so the most reliable reference always remains the chart printed on your food's packaging, then adapted to the individual dog.

The grams shown refer to complete, balanced foods. A very active dog or a puppy may need significantly larger amounts; an elderly, neutered or overweight dog, smaller amounts. If in doubt, ask your vet.

As you can see, the ranges are wide: that's precisely why a chart on its own isn't enough. A 15 kg neutered, lazy dog may do perfectly well on the lower amount in its band, while a same-weight peer that does agility every day needs far more. To move from "roughly" to the precise portion, you need to cross-reference all the factors above.

Kibble, wet food or fresh food: how the ration changes

The same portion "in grams" doesn't apply to every type of food, because what really matters is the calories and the amount of water it contains. That's why the numbers in the chart change so much from one column to the next.

• Kibble (dry): it's very concentrated and contains very little water (around 8-10%). That's why relatively few grams are enough: the kibble amount is usually the lowest by weight. How much kibble a dog should eat depends above all on how many calories that specific product has per 100 g.
• Complete wet food: it contains a lot of water (even 70-80%), so for the same calories the weight of the portion is much higher. It's normal for a dog to eat several hundred grams of wet food a day: much of that weight is simply water.
• Complete fresh food: it sits between the two, with a good moisture content but a higher nutritional density than classic tinned wet food. The portions are therefore generous but not excessive.

An important warning: if you mix more than one food — for example kibble and wet food in the same meal, or kibble and fresh food — you can't add up the full amount of both, otherwise you double the calories. They need to be proportioned, so that the total covers (without exceeding) the day's needs. Complete, balanced recipes, like those among the Pappa Fresh products, make the calculation much simpler because each portion is already designed to cover the meal's entire needs.

Puppies: needs and frequency in the early months

The puppy is a case apart. In proportion to its weight it needs much more energy than an adult, because it has to build bone, muscle and tissue: in the first few months its needs can approach double those of an adult dog of the same weight. That's why it should be fed a food specifically for growth (puppy/growth), richer in protein, calcium and phosphorus in the right proportions.

On frequency, the practical rule is: 3-4 meals a day up to 6 months, then down to 2-3 until around a year of age, and finally to the two meals of an adult. A small stomach wouldn't tolerate a single large ration, and frequent meals help keep blood sugar stable, especially in toy-breed puppies.

Finally, watch the rate of growth: in large and giant breeds you mustn't "push" the puppy to grow too quickly with excessive amounts, because growth that's too rapid can damage skeletal and joint development. Better to follow the food's guidance for the expected adult weight and be guided by the vet at routine check-ups.

Common mistakes in working out portions

Most errors with the amount of food come from a few very widespread habits. Here are the most frequent:

• Measuring "by eye". Filling the bowl on instinct, or using a scoop that's always a little heaped, almost always leads to giving more than needed. The portion should be weighed on a kitchen scale, at least at first, until you learn to recognise it on sight.
• Not counting snacks. Biscuits, training treats, morsels and scraps are calories to all intents and purposes. If you overdo them, the diet goes off balance even with the "right" ration in the bowl. As a rule, extras shouldn't exceed 10% of the daily calories.
• Following only the packaging chart without adapting it. The manufacturer's guidance is designed for an "average" dog and often errs on the high side. It should be used as a starting point and then corrected by observing the dog's real weight and physical shape.
• Not updating the amount over time. After neutering, as the dog ages or if the activity level changes, its needs change. A portion that's "right" at two years old can become excessive at eight.

Overfeeding is by far the most common and most harmful mistake, because it opens the way to being overweight and all the problems that follow. We cover it in detail in our guide to overweight dogs and managing excess weight, and it's also one of the 5 most common dog feeding mistakes.

The simplest way: calculate your dog's exact portion

Between factors to cross-reference, types of food and amounts to adapt, working out how much your dog should really eat can seem complicated. That's why we created a tool that does the calculation for you: enter weight, age, activity level and a few other details, and in two minutes you get the tailored daily portion, already split into meals.

It's the simplest and most accurate way to move from generic charts to your dog's precise amount, with no more guessing by eye. Try the portion calculator: it's free and takes just a few clicks.

With Pappa Fresh, what's more, the single-protein recipes already arrive in portions calculated for your dog's weight and lifestyle: no scale, no sums, no waste — open, pour and the amount is the right one.

In short

How much a dog should eat isn't set by a single number: it depends on weight, age, size, activity level, neutering and physical condition. As a general rule, an adult dog eats twice a day, a puppy three or four times; the chart by weight band is an excellent starting point, but it should always be adapted to the individual animal and the type of food, because kibble, wet food and fresh food have very different calorie densities. The mistakes to avoid are measuring by eye, forgetting snacks in the tally and not updating the portion over time. The most reliable way not to go wrong is to calculate the ration from your dog's real data — which is exactly what our calculator does.
