In canines, part of having great overall well-being is weight management and weight control.

Although that is important in all creatures, it is extremely important in canines, especially those who have adjusted largely to a man’s world. Weight can have a large affect on the body’s ability to process foods, utilize nutrients, and it can affect the body’s ability to work as a unit to promote happiness, high energy, and balanced goodness.

Why it’s important your dog maintains a healthy weight

Depending on your dog’s size (small breed, medium breed, large breed, or giant breed), weight will vary. Yet, maintaining a healthy weight for your dog’s body type is extremely important. In fact, all creatures need to maintain weight control and most humans know this already.

Around half of the nation’s dogs and cats are overweight54% to be specific, which is quite alarming, when we consider the side effects.

Overweight issues in dogs can lead to bigger illnesses such as:

  • obesity
  • osteoarthritis
  • type 2 diabetes
  • high blood pressure
  • heart disease
  • respiratory disease
  • kidney disease
  • cancer
  • short lifespan
  • dehydration
  • lack of energy
  • and other serious issues.

Yet, why exactly are our dogs overweight?

Well, as most people know, weight control usually is linked to the nutrition that fuels the body and the exercise that is given. The nutrition issue is a bit large with dogs because of money and quality of ingredients.

Food quality

Over time as our society has progressed, so has the food industry and the desire for better quality ingredients. This means that all food that is nutritional, natural, and organic is going to be a lot more expensive. Food that is on the significantly cheaper side, on the other hand, usually contains many fillers, pesticides, and other questionable ingredients which are not meant for canines.

Unfortunately, this can cause your dog to gain weight and it may also alter their immune system as well as their organs. Take us humans for example, our bodies have changed and evolved over time and many people nowadays have auto-immmune diseases from GMOS and other foods that are a bit processed.

There is absolutely little to no difference in dogs! In fact, as owner we sometimes even neglect our dogs more than we neglect ourselves (1).

Health issues

As owners, we know our dogs are not going to live until 100 as some humans do. Usually, we think that our dogs have a good eight to fifteen years, if we are lucky. Not very long compared to us, but enough to develop a serious illness.

Our canines have sensitive bodies and they need to be properly monitored. There are so many issues in this world that can affect the health of a dog such as the pesticides that exist in food, the uneducated decisions, and even the toys our dogs are given. Typically, what follows is weight gain, as a result of the dog not being able to move around and meet their daily physical needs.


Beyond the usual issues that occur in the food industry, most owners are guilty of loving a little too much. If this is you, it may sound familiar that you give your dog treats whenever they do a good deed or just because they are…cute. Yet, this can be a big issue in your dog’s weight. If you are constantly feeding your dog treats, that is going to contribute to their sodium amount and to their dietary needs. If you provide excess food, you are also providing an easy ticket onto the weight-gain train.

Lack of exercise

You may also not want to take your dog on daily walks because you do not want to go on walks or because you just do not have the time. But please remember, exercise is important for dogs! They are animals that have the ‘wild’ bred into their bones which means getting fresh air, sniffing their surroundings, and running around is a required activity for your dog.

Now: This is why monitoring your dog’s dietary needs, exercise, and weight is important. Their health will make all the difference in the world to their energy, their well-being, and their happiness (dogs get sad too you know!).

How to determine your dogs ideal weight

If you have a dog, you know that their size, lifestyle, and personality is going to contribute to their weight and to the food they eat. For instance, a Chihuahua is not going to eat or exercise in the same way that a Golden Retriever will.

So: Breed matters and so does the lifestyle you and your dog conduct each day.

Most times, you could look up your dog’s breed, their age, and the other contributing factors that you find necessary to determine what your dog should weigh. Yet, that may not feel accurate because not every dog has the exact birth date written down and not every dog is a pure bred. You could also take your dog to the veterinarian to get an accurate number, but there is a simpler way you can do this.

Using the Body Condition System: Determine your dog’s weight based off of the Purina Condition System. Can you see their ribs? Can you feel extra weight over their ribs? Can you find their waist? Is there a ton of extra weight covering certain aspects of their body?

This system will help you determine and measure your dog based on the actual looks, height, and proportions of your dog. In fact, this may actually be the method your veterinarian uses.

A balancing act: How to keep the good stuff while limiting the bad

Exercise is important. Depending on your dog’s lifestyle and breed, you want to get them out as much as you can each day. Even if you only go for a short walk, get your dog to move and run around. This will help with utilizing the energy that their body wants to utilize from the nutrients you are feeding your dog.

Secondly, you want to keep your dog’s meal plan balanced and you can even follow the meal guidlines off of AAFCO’s standards. There is a minimum and maximum amount of nutrition you are going to want in your dog’s food. When you go to purchase dog food, make sure that you monitor the correct amounts. You do not want to overfeed your dog based on their size and you want to make sure that they receive the correct amount of protein, carbohydrates, and other food sources in their meal (3).

Remember: Every food item will contribute to your dog’s weight. So make sure that you limit the amount of scraps and treats you give your dog.

Weight Loss: Low Carb & Low Fat Dog Food

Each nutrient will contribute to your dog’s health. Protein, carbohydrates, fats, and other nutrition sources are going to help certain organs in your dog’s body and they will also contribute to your dog’s weight. If you are trying to manage and control the weight of your dog, you may want to limit certain nutrients.

Most times, you will probably want to understand carbohydrates and fats a little better.

Now: What is the relationship between my dogs weight, carbohydrates and fats? How do these nutrients change my dog’s body and how do they help my dog’s body?

Dogs & carbs: The relationship between the two

When you think of carbohydrates, you are probably thinking of grains. But, there are so many dog foods on the market that are grain-free? However, does that mean that they are carbohydrate-free? No!

Although dogs do not require carbohydrates in their meal, they can be beneficial. Carbohydrates that contain grains and gluten are not that beneficial for your dog, especially if your dog has a sensitive tummy. But, there are other carbohydrates that come in the form of vegetables that are highly beneficial for your dog’s health and actually help with maintaining weight.

Simply Complex

There are simple and complex carbohydrates and your dog will use carbohydrates as a source of glucose, which helps with processing, utilizing, and digesting other nutrients. It also helps with the nervous system as well as the brain function. However, going into the smallest of details might not be too necessary because your dog does not actually need the nutrients of carbohydrates to survive!

Yet, they do help with ‘holding together’ commercial dog food and they are great fillers. Carbohydrates help your dog process other plant-like materials that their system may struggle with. They provide fiber for your dog’s body, which is definitely a positive material in their nutrition and it can help with weight control and maintaining proper health (4).

When you hear of carbs, you most likely may be thinking:

  • Barley
  • Oats
  • Wheat
  • Gluten

Yet, don’t forget about other nutrients, such as:

  • Corn
  • Rice
  • Potato
  • Starch – like vegetables

Carbohydrates have been known to cause weight gain but that is only if you feed your dog too much of the carbs that do not assist them. Try and add starch – like vegetables and even a little bit of grain, but do not overdo it. Remember: Carbohydrates help but are not a food item that is essential, and definitely not needed in excess.

Which dogs can benefit most from a low fat diet?

Beyond the carbohydrates, you may be wondering about fat.

What is the purpose of fat in my dog’s diet?

As a metric, 10-15% of fat is a great amount for your dog and they should strive to maintain that amount in their daily diet. Fat assists your dog in ways that don’t affect their cholesterol, but too much can cause weight gain and health issues. Fat is necessary for your dog in some regard. Without it, your dog may develop dry skin, itchy skin, and a dull coat.

Additionally, fats are a form of energy that support your dog even more so than proteins and carbohydrates, so you definitely want some form of fat in your dog’s diet (5). This nutrient helps normal development and it contributes to the function of the body’s cells, nerves, muscles, and tissues.

Now: A low-fat diet could be beneficial for your canine. Low fat would start around 10% in the range of normal fat levels and it can go lower than that. This absence and limitation can benefit dogs that cannot process fat or need help in maintaining their weight. Fat and oil is what makes food taste good and it can be what your dog loves, which is a problem when it comes to weight management because your dog will want to eat any and all fat!

Body issues such as hyperlipidemia and pancreatitis require low fat diets and each dog will need a specific dietary standard, according to their health.

What to look for when buying low fat dog food?

If you decide to put your dog on a low-fat diet, then you are going to want to look for certain things. First off, make sure your dog gets high quality fat because it will make a huge difference in their diet. Stick to fats that are from animals for the most part and if you would prefer, you can also add in plant fats. However, animal fat will be the most beneficial.

As mentioned earlier, fat contains more energy than proteins and carbohydrates, which means it is harder for dogs to digest. If your dog has health issues, fat is going to be difficult on the digestive system. Look for the right amount of fat in the dog food you purchase, which can be on the low amount of normal or less (10% or less) or you can have your veterinarian specifically prescribe your dog with the correct amount of fat that they need.
