Every dog owner in the world would surely tell you that the saying is true - dog really is a man's best friend. And it goes both ways! A responsible owner like yourself treats their pet with love and respect, as they are one of your closest friends. We love our dogs so much that, occasionally, we might end up overdoing it a little - for example, by overfeeding them. After all, we just want them to be happy - and everyone knows a happy dog is one whose bowl is full! 🐶

Unfortunately, obesity is getting worse among our best friends, and with it comes a number of health complications. Especially today, in the tough times of quarantines, restrictions on going out, and not seeing your friends, it's easy to shower your pup with love a bit too much. But worry not! Helping your dog maintain a healthy weight is not as complicated as you may think - it all comes down to properly catering to his or her nutritional needs. This is precisely what our dog calorie calculator is for - use it to estimate your dog's daily calorie requirements and calculate how much food you will need to provide them with in order to meet these requirements. With our help, you will be able to keep your dog happy and healthy, which will result in a long and happy life!

We would like to thank Dr Olga Lasek, PhD, an animal nutrition expert associated with the University of Agriculture, Krakow, for her immense help in supervising the creation of this calculator.

Does an ever-full bowl really equal a happy dog? Some dog obesity facts.

The Association of Pet Obesity Prevention reports that, in 2018, around 56% of all dogs in the US were overweight or even obese. Even more shockingly, a 2018 study revealed that dogs even as young as six months - practically still puppies - already face this problem!

"Why should we even consider it a problem?", some might ask. "What matters is that my dog is happy - why worry about an extra kilogram or two?"

Here's why - eating is one of the main driving forces of all animals, so your dog will most likely be content to eat all the time, even if their tummy is already full. Dogs don't understand the health implications of being too heavy, and it is the responsibility of their owners to make sure they don't suffer from them.

The most common health complications caused by obesity in dogs include (but aren't limited to):

  • Breathing and heart problems, due to the huge amount of work a dog's heart has to do to pump blood around a bigger than average body.
  • Arthritis, due to the extra strain the excess weight puts on your dog's joints.
  • Digestive disorders, including constipation and flatulence - a rather unpleasant ordeal for both the dog and the owner.
  • Heat intolerance, due to all the extra fat. Especially in a warmer climate, the summer months may be unbearable for overweight dogs.
  • Liver problems, as excess fat tends to build up in the organ, impairing its function.

With all these (and many more) health issues in mind, it's easy to see why you should make sure your dog is a healthy weight.

What are the most common causes of pet obesity?

In most cases, it's the combination of two things: excessive food intake and insufficient physical activity for their diet. In addition, the risk of obesity is usually increased in neutered dogs, as hormonal changes influence their metabolism.

So, how to prevent all of these problems? The options are countless. Naturally, you can start by using our dog calorie calculator to find out your dog's nutritional needs!

How to use the dog calorie calculator?

The way the dog calorie calculator works is really simple. To use it, just follow these instructions:

CALCULATING THE DAILY CALORIE INTAKE

  • start by choosing how much physical activity your dog typically gets. To determine that, take a look at the table below. Please note that this field also covers the age, as an old dog's activity is generally low.
Activity type Characteristics
Low activity (including elderly dogs) Less than 1 hour of exercise a day, for example walking on a leash. Also applies to elderly dogs*.
Low intensity moderate activity 1 - 3 hours of low intensity exercise per day, for example walking on a leash.
High intensity moderate activity 3 - 6 hours of high intensity per day, for example unleashed walks with considerate amounts of running, games, playing with other dogs, etc.
High activity 3 - 6 hours of work per day, for example sheep dogs.
  • Input the weight of your dog. The activity and weight of your dog are what determine their daily caloric need.
  • With those values, the calculator will figure out what the daily calorie intake of your dog should be.

*How to determine whether your dog is a senior? Your dog's breed determines its lifespan, so it may get a little confusing. A number of things such as fur discoloration and general condition may indicate that your friend is entering the golden years of his or her life, but, in general, it's reasonable to use the following rule of thumb based on your dog's weight:

  1. Small dog (below 20lbs/9kg) - age 11+
  2. Medium dog (21-50lbs/9-20kg) - age 10+
  3. Large dog (51-100lbs/21-45kg) - age 9+
  4. Giant dog (above 100lbs/45kg) - age 8+

Now that you know how many calories your dog needs, you have the option to calculate two additional things:

  • the amount of food your dog should eat to meet their caloric needs, based on a food's energetic content,
  • if you're not sure about a food's energetic content, you can calculate it based on the information of its ingredients, provided on the packaging. Please pick "yes" or "no" in the second part of the calculator to indicate if you want to calculate these things, or if you're satisfied with your calculations for far. For each "yes", an appropriate part of the calculator will appear.

CALCULATING THE AMOUNT OF FOOD

Calculating the the size of your dog's daily meals based on its caloric content is easy. All you have to do is input how many calories there are in 100 grams of the food. The calculator will compare this information with what it already knows about your dog's needs, and return how much to feed him or her daily. If you want to know how many bags that is or how long a bag would last, you just need to declare the volume of a package you usually buy.


CALCULATING THE CALORIC CONTENT OF SPECIFIC FOODS

If you're unsure of exactly how much energy there is in the food you give your dog, or just want to make sure that the info on the packaging is correct, you've come to the right part of this calculator.

To calculate the caloric content, you need to check the packaging for the following things, and put them in the calculator:

  • Dry matter - which is the part of the food that would remain after getting rid of all of the water in it. It's a valuable piece of information, as this is where all the nutrients come from. In fact, many experts state that knowing the dry matter percentage is crucial when it comes to comparing different kinds of dog food, especially canned.

  • Crude ash - sometimes labeled as "incinerated residue" or "inorganic matter". It may sound scary, but it actually refers to the amount of important minerals present in the food. This includes calcium, magnesium, phosphorus and other crucial elements.

  • Crude protein - as the name suggests, this is the total amount of protein present in the food. Contrary to popular belief, this is not restricted to protein from animal-sources - it covers all kinds!

  • Crude fat - this tells you the total fat that is in your dog's food. Unfortunately, this includes both the good, essential fats, and the bad ones that will do more harm than good. You might need to read the list of ingredients to see where it mostly comes from.

  • Crude fiber - fiber, the indigestible part of plant foods, it crucial in keeping the digestive system in good shape. It aids healthy bowel movements, and allows for the balanced growth of healthy gut bacteria.

A note on using the dog calorie calculator

Please note that there are some special cases in which the results obtained from this calculator will not apply. These include pregnancy or nursing newborn pups. In these cases, your dogs nutritional needs differ from usual, and may be influenced by a variety factors, such as the number of pups, the moment of pregnancy, etc. The same applies to dogs with underlying health conditions - if your dog has some sort of lingering health issue, they probably need a special diet. Please keep in touch with your veterinarian, and, if your dog is pregnant, nursing or has any other kind of special needs, make sure their diet complies to the vet's recommendations.

How to tell if my dog is obese?

Surprising as it may be, many owners cannot tell whether their dog is the correct weight or not. The easiest way to estimate whether your pet's weight is healthy is to go to one of the many available Body Condition Score Charts. The Pet Food Manufacturer's Association provides a very detailed insight into this system. Remember, however, that this is just a guide, and should not be used as a definitive judge of your dog's health! If you're unsure of your dog's body condition, the best idea is to consult your veterinarian.

Most body condition charts go by the following standards:

1. VERY THIN

Exercising is fun! Ideas for activities that will help your dog lose weight healthily

If your dog is over its ideal weight, providing it with more active fun is the way to go! Even in the tough times of quarantines and limited time outdoors, it's possible to keep your dog active and healthy. Check out these ideas for fun and stimulating activities, both for those with their own yards, and those who need to make do with staying indoors.

1. Indoor exercise ideas - whether it's because of quarantine or bad weather, it's possible to have fun and exercise with your pup indoors too! 🐕

  • Tug - dog's love a good ol' game of tug-o-war. Pet stores offer plenty of ropes and soft toys designed specifically for this purpose.

  • Inside fetch - if your place is big enough, you should have no problem with playing fetch inside. Sure, your dog may not run quite as much as outside, but it's still a good amount of activity. Remember to remove any potentially breakable items and use a soft toy.

  • Bubbles - many dogs find themselves absolutely entranced by soap bubbles. Chasing them and jumping to catch them might provide your dog with just the right amount of activity.

  • Learning physical tricks - contrary to the popular belief, it's never too late to teach your dog a new trick. Try some more physically demanding ones, such as spins, rollovers weaving between your legs.

  • Puzzle toys - available in most on-line pet stores, puzzle toys with treats stored inside them as a reward will provide your pup with both physical and mental stimulation they need to stay healthy.

2. Yard exercise ideas 🏡 - if you're lucky enough to have your own yard, keeping your pup active is not challenging at all! You can do:

  • Fetch - not many dogs are able to resist running after their favorite toy. Perfect if you have a fenced yard - you can be sure that your dog will never get bored of this!

  • Agility - while professional agility is a challenging sport requiring loads of training and dedication both from the dog and the owner, you can easily set up a simple, casual obstacle course in your yard, using whatever you have at hand - old furniture, toys, branches. Your pup is going to be thrilled to learn something new!

  • Digging - we understand that you may not want your pup to dig through your lawn. How about a small designated area to do so instead? Consider ordering a small child's sandbox on-line, and enjoy the sight of your friend having the time of his or her life. Note: if possible, try to get a sandbox with a cover, so that it does not attract your local outdoors cats - we believe you know why 😉
