Why Do Dogs Gain Weight?

Overweight Dachshund

Dogs can gain weight for a variety of different reasons.

Before you do anything it is important to understand why it is your dog has become overweight. There are many reasons for this, some are obvious, and some are not, but listed below are some of the most common reasons why your pooch might be piling on the pounds.

Too Much Food

While this might seem like an obvious contributing factor, many owners do not understand their dog’s nutritional needs. However, it is quite simple, in that if your dog eats more calories than he burns, he will gain weight.

The amount of food you feed your dog will be dependent on many factors, such as age, breed, and energy levels, so there is no one size fits all rule here. Generally, dogs need around 30 calories per pound of weight every day, but you can calculate how much food he should be eating with this calorie calculator.

All of our high-quality food recommendations below offer feeding instructions on their packaging, but if you are in any doubt about how much to feed him, then speak to your Veterinarian who will be more than happy to advise you.

Not Enough Exercise

Exercise is crucial for a healthy body, and it will help to both lose the excess weight and maintain it when he has achieved his weight goals. Again, all dogs are different, in that some need a little exercise, such as a King Charles Spaniel, and others, like the Australian Cattle Dog, need a lot of it.

Most dogs need between 20 and 60 minutes of exercise every day, with some breeds needing much more and some need less, but if they do not get the exercise that they need then they will become overweight and unhealthy.

As dogs become older, or even if they have temporarily injured themselves and need to recover with rest, they naturally become more sedentary, and as such, they will need less food. Your Veterinarian may recommend a dog food nutritionally engineered for senior dogs as a result.

Breed Type

Some dog breeds are more prone to obesity than others. For example, the Pug is notorious for easily putting on weight, and many Pugs are fed dog food with a lower calorie count for their entire adult life. The Labrador is also known to become too porky as he has a gene missing that tells him when he is full, so he is forever hungry and consistently overconsumes his dog food.

Some breeds, like the Greyhound, are super skinny, and Siberian Huskies can eat their dog food without worrying because of their super-fast metabolism and eat very little despite being one of the most energetic dog breeds. Again, your Veterinarian will be able to advise you what your dog’s healthy weight should be.


If you are still not sure as to why your pooch might be piling on the pounds then it is time to take him to his Veterinarian, as there might be an underlying cause for his weight gain. Just like us humans, significant weight loss or weight gain could be a symptom of a serious medical condition, such as Cushing’s Disease or Hypothyroidism.

The majority of these conditions can be managed and are not life-threatening, if left untreated they can cause further issues, so it is best to get this gain investigated and manage such conditions before they worsen.

Buyers Guide

Overweight Dog on a Scale Losing Weight
There are several important factors to consider when buying weight loss dog food.

Hopefully, you will now have some idea about why your pooch might have gained his extra weight, and now it is time to focus on his nutrition. In addition to all-natural high-quality recipes, listed below are the extra things to look out for in a weight management recipe:

High Fiber Content

Fiber derives from plants and it is a form of complex carbohydrates that will fill your pooch up for longer without many calories. Although it has little value in terms of nutrients, it is very important as it keeps the digestive system functioning well and it removes waste from your dog’s body that might otherwise be harmful, all of which assist in healthy weight management.

Most weight management dog foods will have a high fiber content for these reasons, and high fiber content is anywhere between 6% to 12%. However, not all dogs do well on higher fiber content, so we have included some lower fiber content foods on this list too. Some of the best higher fiber ingredients in dog food include green veggies, carrots, sweet potatoes, pumpkin, oats, legumes, apples, and peaches.

Low Calories And Low Fat

The majority of weight management recipes will be low in calories and fat, because, quite simply, if your pooch doesn’t burn off what he eats he will put on weight. If you want your pooch to lose weight, then he needs to eat food that is low in both fat and calories.


L-Carnitine is a vitamin-like amino acid that aids healthy metabolism, and it has been scientifically proven to aid weight loss in dogs and cats. Many weight management recipes will list L-Carnitine in the ingredients, so this is another key weight loss ingredient to look out for.

Other Tips For Losing Weight

While the above foods are the best around for weight loss, they are not a miracle cure, and his weight loss journey needs more than just the right nutrition, so be sure to implement the following tips.

  • Exercise:  Dr. Ochoa at the American Kennel Club recommends that you create an exercise plan, which you need to stick too. If your pooch is particularly overweight then be sure to start off slowly, and begin your day with a 10 to 15-minute walk.
  • Weekly Weight Monitoring: Just as you would with your weight, be sure to monitor his weight weekly and keep a diary of it. Dependent on the size of your dog, a few extra pounds might not be visible, but by monitoring his weight you can ensure that you know to feed him fewer treats and exercise him that bit more the following week
  • Patience: Be patient with your pooch, and remember that crash dieting is just as bad for him as it is for us humans. If you are worried that he is not losing weight as he should then speak to your Veterinarian, and they will be able to advise you accordingly.

Frequently Asked Questions

Is my dog overweight?

The Association for Pet Obesity Prevention found that in 2018, over 55% of dogs in America were overweight or obese, so it is more than likely that at some point during your dog’s life he might find himself slightly heavier than he should be. The easiest way to check if your dog is overweight is simply by looking at him. Looking from above, you should be able to see a defined waist towards his rear, rather than an oval shape. When you look at him from the side you should be able to see that his waist is raised and clearly at a different level compared to his abdomen. When feeling his chest you should be able to feel his ribs without pressing too hard, and if you can’t feel them, then it is likely that your pooch is overweight.

How often should I exercise my dog?

This depends, but usually, it’s recommended a minimum of 30 minutes per day outdoors with some type of walking activity.

Are there any brands that help weight loss more than others?

Any of the dog food brands we’ve mentioned above should help your pup lose weight if used in conjunction with a daily exercise routine.
