What causes dogs to gain weight?
Like humans, dogs gain weight when they don’t metabolize all the calories they take in and burn off through exercise. These extra calories are then stored as fat.
As each dog and dog breed is different, it can be challenging to calculate exactly how many calories your dog burns each day.
Some dogs are more predisposed to weight gain. For example, older dogs are more prone to obesity as their metabolism slows with age.
Also, inactive dogs who don’t expend their energy by playing or running can put on weight more quickly, as can dog recovering from injury or illness.
Certain medical conditions can also affect your dog’s metabolic rate.
For example, these include hypothyroidism, which is a condition in which the thyroid gland fails to produce the hormone necessary to control weight.
Certain medications, such as corticosteroids, can also lead to weight gain.
Also, dogs that have been neutered or spayed tend to have a lower metabolic rate than unaltered dogs. Dogs who are allowed to free feed also tend to gain weight quicker than others.
Health Risks for Overweight Dogs: Why should your dog need to lose weight?
Dogs that can maintain their ideal body weight can live up to 1.8 years longer than other canines.
Any extra weight can lead to your dog experiencing reduced immune system function and developing several health issues. These can include:
- An increased risk of diabetes mellitus
- Cardiovascular problems such as heart disease and high blood pressure or hypertension
- An increased risk of joint injuries
- Development of cancers, especially intra-abdominal cancers, mammary tumors, and bladder cancer
- Liver problems, such as fatty liver disease
- Heat intolerance and a predisposition to overheating
- Difficulty breathing
- Fatigue and lethargy
- Skin and coat issues
- Reproductive failure
How do you know if your dog is overweight?
Each breed of dog will have an ideal weight, and your vet can help determine precisely what that is for your particular pup.
If you are unsure, there are a few simple ways you can check to see if your dog may be overweight.
The first is to hold your hands around your dog and press down; if you can feel your dog’s ribs without applying too much pressure, they are at a healthy weight.
Healthy dogs also have a more hourglass shape to their bodies with a defined waist; an oval or round-shaped dog could be overweight.
You can also compare your dog’s weight against their AKC breed standard. A dog that is considered obese will weigh 10-15% above its healthy body weight.

How can you help your dog lose weight?
While switching to a good weight loss diet will help your dog lose weight, you can do a few other things to help the process.
This includes increasing the amount of exercise your pup gets. To prevent injuries, gradually introduce an exercise regime to your dog.
Don’t try to do too much too quickly but instead start with regular, short walks or short bursts of playtime in the yard.
You should also avoid giving your dog excess treats. Treats are a particular problem with smaller dogs as they can represent a significant portion of their daily caloric intake.
People food and table scraps should also be avoided, although healthy treats like green beans or bananas can make good alternatives to treats.
Buyer’s Guide: Choosing the right food for overweight dogs
Not all weight loss foods are created the same, and there are a few things to look out for when choosing the best weight-less food for your pup.
Dog Nutrition 101: What kind of food does your dog need for weight loss?
Dog food for overweight pups should contain above-average protein levels, below-average fat levels, and below-average calories.
Regular dog food has quite a bit of fat, and carbohydrates like potatoes and cereal grains can cause your dog to put on weight. Also, these foods contain too little lean meat.
Weight loss formulas, on the other hand, will be low-fat recipes and significant amounts of meat-based proteins.
Things to look for when selecting dog food for weight loss
While weigh-less foods have fewer calories than other dog food, they still contain high levels of carbs and fiber so that your dog feels fuller for longer.
The increased protein levels of these foods also help to decrease the calorie content.
When it comes to looking for the best dog food for weight loss, it is best to go for food that has less than 400 calories per cup.
Less than 300 calories per cup are ideal, although most foods tend to sit between 300 and 400 calories per cup.
You also want to select a food that your dog will enjoy eating. The last thing you want is for your dog to stop eating altogether.
Besides being super tasty, your dog’s food should also contain the necessary vitamins and minerals your pup needs to stay healthy.
Good weight loss food is also fortified with probiotics which help with proper gut functioning, ensuring your dog digests their food correctly.
In addition to choosing a food that matches all of the above criteria, you should also look for food that has been manufactured in a country with high safety standards.
This includes the United States, Canada, the United Kingdom, Australia, New Zealand, and most Western European countries.
Good dog foods should also contain whole protein as the primary ingredient, such as deboned chicken or beef.
Any unidentified meat by-products or meals should be avoided, as should any artificial flavors, colors, or preservatives, as these can all trigger food allergies.
To grain or not to grain: Do dogs need grain-free food?
Grain-free pet food will not necessarily help your dog to lose weight.
While grain-free diets typically have fewer carbs, the fat content of your dog’s food is the main thing to consider when it comes to losing weight.
Grain-free diets can, however, help to limit some skin and food allergies with your pet.
However, due to the potential link between grain-free diets and heart issues, many vets prefer to recommend a limited ingredient diet to dogs prone to allergies.
These diets do not contain a blend of carbs but instead focus on one whole grain.
Frequently Asked Questions (FAQs)
How much should you feed your dog to lose weight?
As each dog breed is different, it is impossible to determine how much you need to feed your specific dog for him to lose weight.
Also, every brand of dog food will have different feeding recommendations.
Thus, it’s best to consult the bag to determine how many cups of food you need to be providing your dog based on his size and weight.
The best way to calculate your dog’s caloric intake is to determine his resting energy requirements (RER). This is how much energy your dog burns when they are simply sitting, breathing, and just being.
To determine the RER, you need to take your dog’s weight in kilograms and raise it to ¾ power. According to this formula, a 10 kg (22 pounds) dog would burn 400 calories.
These calorie numbers need to be multiplied by either 2 or 3 for puppies, by 1.8 for unneutered adult dogs, or 1,6 for spayed or neutered adult dogs.
The number need not be multiplied at all for dogs that are already overweight. Most vets recommend cutting the caloric intake of overweight dogs by 25%.
You can also use a weight chart, like those published by the World Small Animal Veterinary Association, to determine your dog’s specific calorie needs.
When and how often should you feed your dog?
You might think that feeding your dog once a day will help them lose weight; however, this is not the case. Feeding your dog once a day can lead to malnutrition and starvation.
It is best to provide your adult dog twice a day while puppies should be fed three and four times a day. Your dog’s daily caloric allowance should be split between these meals.
Your dog’s daily feedings should be spaced between four and six hours apart, leaving enough time between meals and before bed for your dog to digest its meals properly.
Feeding your dog late at night will also increase the chance that your dog needs to go to the loo during the night.
Free feeding, where you leave food out for your dog throughout the day, is not recommended, particularly with dogs prone to weight gain.
Can you give homemade food for your dog?
Giving an overweight dog homemade food may not be the best choice as you won’t necessarily know what ingredients to include for the right calorie, fat, and protein intake for your puppy’s weight, size, and health.
While it can be challenging to get the formula right for an overweight dog, companies out there specialize in creating fresh, human-grade meals using all-natural ingredients.
These companies will portion their homemade meals accordingly so you know exactly how much to feed your dog each day and you can even customize diets to meet specific weight loss goals.
What’s the best way to switch your dog to weight-loss food?
Whenever you change your dog’s diet, it is best to gradually change if you don’t want to end up with a pup with an upset stomach.
Dog’s have very sensitive stomachs, and the slightest change in diet could lead to several digestive issues.
Start by mixing in around 25% of your new weight loss food with your dog’s old food, gradually increasing that amount each day over a week until you have made a full transition.
What’s the safest rate of weight loss for an overweight dog?
Try not to force your dog to lose weight too quickly. Rapid weight loss can lead to some severe health problems. The safest weight loss rate should be about 1-2% of your dog’s total body mass per week.
Are dogs ever full?
Most dogs will realize when they are full and will stop eating. That said, some breeds will not know when to stop and will even search out free food left lying around.
Should you leave water out for your dog all day?
Dogs need to drink an ounce of water per pound of their body weight all day. As a result, water should be readily available to them all day.
The only time you would not leave out water for your dog all day is when you are housebreaking or potty training.
In this instance, your water bowl can be removed at night, so your puppy doesn’t suddenly need to go potty when you are asleep.
Can dogs eat lying down?
Some dogs will eat lying down, and while this can seem alarming at first, it is quite normal practice. Dogs in the wild also often eat their prey while lying down.
If your dog suddenly switches from eating standing up to laying down, be sure to check their overall health and take them to a vet to ensure they are not sick.
Why do dogs sleep after eating?
You may find your dog is more hungry after a good nap. This is because resting allows your dog time to digest their food properly.
That said, try and stop your dog from performing activities immediately after a meal, as this could lead to bloat issues.
If Your Dog is Overweight, Talk to Your Vet Before Choosing a Dog Food
Finding the best dog food for your pup is an essential part of their weight loss journey. However, before changing over your dog’s diet, it’s best to consult your veterinarian in this regard.
Your vet will be able to provide accurate advice based on your dog’s weight, size, breed, and overall health. Your vet may also decide to give your dog a prescription diet if their condition is terrible.
