How Much Should I Feed My Dog? Complete Feeding Guide by Weight & Age

Standing in your kitchen with a bag of dog food and a measuring cup, you have probably asked yourself this question more than once: "Am I feeding my dog the right amount?"

You are not alone. This is one of the most common worries for dog owners across the UK. Feed too much, and your dog might gain weight. Feed too little, and they might not have enough energy. Getting it right matters for your dog's health and happiness.

The good news? Feeding your dog does not have to be complicated. This article will help you determine the exact amount to feed your dog based on their weight, age, and lifestyle.  

 

Why Getting the Feeding Amount Right Really Matters

Your dog food is their fuel. Just as you would not put the wrong fuel in your car, you want to ensure your dog receives the correct amount of food each day.

When you feed your dog properly, you will notice:

Their energy levels stay steady throughout the day. They maintain a healthy weight without getting too heavy or too thin. Their coat looks shiny and healthy. They have good digestion with regular, firm stools. They seem happy and content after meals.

On the other hand, feeding the wrong amount can cause problems. Too much food leads to weight gain, which puts stress on your dog's joints and heart. Too little food leaves your dog hungry and lacking energy.

In the UK, vets say that more than half of dogs are carrying extra weight. This often happens because owners are not sure how much to feed, or they give too many treats on top of regular meals.

Wet Food vs Dry Food: What Changes?

Wet food contains much more water than dry food. This means you need to feed more wet food by weight to give your dog the same calories.

As a general rule, you need to feed about three to four times more wet food than dry food. So if your dog needs 300 grams of dry food, they would need roughly 900-1200 grams of wet food instead.

Many UK dog owners do mixed feeding, giving both wet and dry food. This is perfectly fine. Here is how to work it out:


If you want to give half wet and half dry, take your dog's daily dry food amount and divide it in half. Then replace the other half with three times that amount in wet food.

For example, if your dog needs 400g of dry food daily:

  • Give 200g dry food
  • Give 600g wet food
  • Total: 200g dry + 600g wet per day

 

Feeding Puppies: Special Considerations

Puppies need more food than adult dogs because they are growing. They also need to eat more frequently throughout the day.

Puppy Age

Feeding Frequency

Food Type

Notes

Under 3 months

4 times per day

Puppy-specific food

Small, frequent meals for tiny tummies

3-6 months

3 times per day

Puppy food

Rapid growth phase - they eat A LOT

6-12 months

2 times per day

Puppy food

Still growing but slowing down

12-18 months (Large breeds)

2 times per day

Puppy or adult food

Transition based on breed size

 

Puppy feeding amounts vary hugely depending on breed. A Chihuahua puppy and a German Shepherd puppy have very different needs. Always check your specific puppy food's guidelines and ask your vet at puppy vaccinations if you are unsure.

 

Feeding Senior Dogs: What Changes as Their Age

Most dogs are considered senior around 7-8 years old, though large breeds age faster. Senior dogs typically need fewer calories because they are less active.

You might notice your older dog:

  • Sleeps more
  • Walks more slowly
  • Has less interest in playing
  • Gains weight more easily

When your dog reaches their senior years, you may need to reduce their food by about 20%. Watch their weight closely and adjust accordingly.

Many UK pet food brands make senior-specific foods. These often have:

  • Fewer calories per portion
  • Added joint support ingredients
  • Easier to digest proteins
  • Extra fiber for digestion

At Buggaz.co.uk, we stock a range of senior dog foods suitable for older dogs' changing needs.



How to Tell If You Are Feeding the Right Amount

The best way to know if you are feeding correctly is to look at your dog's body condition. You should be able to:

  • Feel their ribs easily when you run your hands along their sides, but not see them clearly. If you cannot feel the ribs at all without pressing, your dog is overweight. If the ribs stick out visibly, your dog is underweight.
  • See a waist when you look down at your dog from above. Their body should curve inward slightly behind the ribs. No waist visible means they might be carrying extra weight.
  • Notice a tuck when you look at your dog from the side. Their belly should tuck up slightly from chest to back legs. A hanging belly or no tuck suggests too much weight.

If your dog matches all three points, you are feeding the right amount. If not, it is time to adjust.

 

What About Treats and Chews?

This is where many UK dog owners go wrong. You carefully measure your dog's meals, but then throughout the day you give:

  • Training treats
  • A dental chew
  • A bit of your toast at breakfast
  • Some carrot sticks as a healthy snack
  • A dog biscuit when they have been good

All of this adds up. Treats should make up no more than 10% of your dog's daily calories.

Adjusting for Weight Loss or Gain

Has your dog gained weight? You notice their waist has disappeared and you can barely feel their ribs. Time to reduce their food.

Cut their daily amount by 10-15%. So if they were having 400g per day, reduce to 340-360g. Stick with this new amount for two to three weeks, then check their body condition again.

Still overweight? Reduce by another 10%. Keep checking every few weeks until they reach a healthy weight. Then maintain that amount.

Has your dog lost weight? They look too thin and you can see their ribs clearly. Time to increase their food.

Add 10-15% to their daily amount. If they were having 300g per day, increase to 330-345g. Check again in two weeks.

Important: Sudden weight loss or gain can indicate health problems. If your dog's weight changes quickly without you changing their food, book a vet appointment.

 

Special Feeding Situations

  • Pregnant or Nursing Dogs: Need significantly more food, especially in the last few weeks of pregnancy and while nursing puppies. Your vet will give specific advice, but expect to increase food by 25-50% or more.
  • Working Dogs: Farm dogs, gun dogs, and other working dogs burn many more calories. They might need double the standard amount on working days.
  • Dogs Recovering from Illness: May need special food or different amounts. Follow your vet's specific recommendations.
  • Dogs with Health Conditions: Diabetes, kidney disease, or other conditions often require special diets and feeding schedules. Always follow vet advice for health issues.

 

Common Feeding Mistakes UK Dog Owners Make

  • Free Feeding: Leaving food down all day. This makes it impossible to monitor how much your dog eats and often leads to weight gain. Set mealtimes are better.
  • Using Cups Instead of Weighing: A cup of one food is not the same as a cup of another. Kitchen scales give accurate portions.
  • Forgetting to Adjust for Treats: Your dog might be getting the right amount of meals but too many extras throughout the day.
  • Following the Guide Too Strictly: The feeding guide is a starting point. If your dog is gaining or losing weight, adjust the amount regardless of what the packet says.
  • Not Adjusting for Age: What your dog needed as a young, active two-year-old is not what they need as a slower eight-year-old.
  • Giving Too Much Because They Look Hungry: Dogs are opportunistic eaters. Just because your dog acts hungry does not mean they need more food. Many dogs would eat until they burst if allowed.

 

How to Measure Dog Food Accurately

For the most accurate feeding, use kitchen scales. Here is how:

Place your dog's bowl on the scales. Press the tare button to zero it. Add food until you reach the correct weight in grams. Done.

If you prefer using a measuring cup, weigh out the correct amount of your dog food once and pour it into the cup. Mark the level with a permanent marker. Now you know what the right amount looks like in that specific cup with that specific food.

Remember: Different foods have different densities. A cup of one brand might weigh 100g, while a cup of another weighs 120g. This is why weighing is more accurate.

 

Breed-Specific Feeding Considerations

Some breeds have special feeding needs:

  • Labradors and Retrievers: Notorious for being food-obsessed. Will often act hungry even when full. Stick to measured portions and do not give in to begging.
  • Deep-Chested Breeds (Great Danes, German Shepherds, Setters): Risk of bloat (gastric torsion). Feed smaller, more frequent meals. Avoid exercise right before or after eating.
  • Flat-Faced Breeds (Pugs, Bulldogs, French Bulldogs): May eat too quickly and gulp air. Use slow-feeder bowls. Feed smaller portions more often if they struggle.
  • Small Breeds (Chihuahuas, Yorkshire Terriers): Fast metabolism. May need to eat more frequently. Can be picky eaters.
  • Working Breeds (Border Collies, Belgian Shepherds): High energy needs. May need more food than you expect for their size.

 

When to Seek Professional Advice

Contact your vet if:

Your dog loses or gains weight suddenly without diet changes. They refuse food for more than 24 hours. They seem constantly hungry despite eating the right amount. You notice digestive problems (vomiting, diarrhea, constipation). Your dog is under or overweight and you cannot fix it. You are unsure about your dog's specific needs.

At your dog's annual health check, ask your vet to assess their body condition. Vets can give helpful advice on whether you need to adjust feeding amounts.

 

Multi-Dog Households: Feeding Multiple Dogs

If you have more than one dog, feeding can get tricky. Some dogs eat faster than others. Some might steal food from slower eaters.

Here is what works for many UK multi-dog homes:

Feed dogs in separate spaces. This could be different rooms or using baby gates to create divisions. Each dog gets their own bowl with their own portion. Stay nearby while they eat to prevent food stealing. Pick up bowls when they finish, so there is nothing to guard or steal.

Each dog should get the amount right for their individual size, age, and activity level. Do not just give them all the same amount because it is easier.

Seasonal Changes and Feeding

Your dog's needs might change slightly with the seasons:

Winter: Dogs who spend time outdoors might need a bit more food to maintain body temperature. Working dogs in cold weather definitely need more. Indoor dogs who walk less in bad weather might need slightly less.

Summer: Many dogs eat less in hot weather. This is normal. Make sure they drink plenty of water. Active dogs swimming and playing in the heat still need full portions.


Final Thoughts

Feeding your dog the right amount is not about following rigid rules. It is about paying attention to your individual dog and adjusting as needed.

Start with the feeding guide on your dog food packaging. Watch your dog's body condition over a few weeks. Adjust up or down based on what you see. Remember that treats count. Stay consistent with mealtimes.

FAQs

How often should I feed my dog?

Generally, it is best to feed your dog twice a day, but how often to feed your dog varies based on your dog’s age, breed, size, and any underlying medical conditions.  

Is 2 cups a day enough for a dog?
Two cups a day may be enough for some medium-sized dogs, but it is not suitable for every dog. Small dogs usually need less, while large or active dogs need more food. Measuring food by weight is more accurate than using cups.

How much food should I feed my dog, in kg?
A dog food feeding chart shows the daily food amount based on your dog’s weight in kilograms. For example, a 10 kg dog may need around 150–200 grams per day, depending on the food. Always check your specific brand’s chart for the most accurate amount.

What are the signs of overfeeding a dog?
Common signs of overfeeding include weight gain and a loss of a visible waist. You may find it hard to feel your dog’s ribs without pressing firmly. Low energy levels and digestive issues can also be signs of overfeeding.
