Buying the best low-fat dog food can be a terrifying experience because of how deceitful most dog food manufacturers are. They want to convince you because if they do, you will embark with them for months, if not years. They use all the tricks in the book to convince you that their special low-fat dog food formula is the best.

Reduced-fat diets for dogs are a way of offering the owner a weight control instrument to keep the calorie count low while keeping the satiety high. Dogs are hungry beasts and if you don’t feed them enough, they will find something else to chew on (yep, that would be dramatic for your furniture.)

We’ve put together this comprehensive article split into three parts:

  1. Buying Guide — how to choose the best low-fat dog food
  2. Reviews — our top fat loss dry dog foods for all budgets
  3. Cons — nothing is perfect, and a low-fat diet isn’t either

Fat is not the devil and you should still monitor how many carbs you are feeding your dog; however, a gram of fat represents 9 calories while a gram of protein or carbohydrate is only 4 calories. Therefore, low-fat dog food will naturally reduce the dog’s calorie intake throughout the day.

Choosing The Best Low Fat Dog Food

A low-fat diet is just one of the most popular diet choices along with gluten-free, low-carb, and grain-free diets; but will it work on your dog? Some other diets will aim at reducing carbohydrates instead of fats, this is the case with grain-free dog foods, for example.

Surely, our canine friends might tend to be overweight when not exercised properly, and this is the reason why most people begin to think that low-fat dog food can be necessary for them. But is it?

Why Obesity is a Threat to your Dog

As with humans, dogs are at a big risk if you feed them with too many fatty foods. Over 35 million American dogs are overweight, which is a whopping 45% of the entire population. You don’t want your dog to add up to the numbers, right?

Here are some health problems that can occur in an obese or overweight dog:

  • Diabetes — Like humans, when dogs tend to have a sweet tooth combined with excessive amounts of food every single day, diabetes is more likely to come for them and once dog diabetes affects your dog, it’s a lifelong battle of everyday tests and effort.
  • Mobility Problems — Arthritis and joint pains may also occur if a dog is overweight. This is mostly because dogs will have less time for exercise due to eating habits and obese physique. The repercussions can be severe at a later stage in life with important problems targeting your dog’s joints.
  • Cardiac and Respiratory System — We are all aware that obesity in the human world may lead to heart attacks – this is the same for dogs. Difficulty in breathing is not too far if your dog doesn’t live a healthy lifestyle.
  • Pancreatitis — Pancreatitis is also a product of a high-fat diet and an outcome of dog obesity, which leads dog owners to switch to low-fat dog foods. When the pancreas gets inflammations, it becomes painful for the dog because the pancreas becomes the spot for the digestive enzymes instead of in the small intestine. This health problem is commonly known through symptoms such as vomiting, diarrhea, loss of appetite, lethargy, back-arching, swollen abdomen and much more.

Obesity takes months of consistent effort in order to be cured; sometimes years. Dieting is the main lever but not the only one since calories can also be burnt through activity and regular exercise. If you have to stay at home for whatever reasons, perhaps invest in a dog treadmill.

The Right Low Fat Formula For Dogs

calories in one gram of protein, carbohydrates, alcohol and fat
To understand why a low carb dog food is good, you need to understand why fats are problematic when your dog needs to get into a calorie deficit.

Around 15 to 20% of fat is most likely inside Fido’s high-quality dog food nowadays, despite the fact that the recommended amount of fat should only be 5% for adult dogs who aren’t very active. In fact, protein-based and grain-free foods may contain higher amounts of fat which can be beneficial if you are after the best dog food for a pitbull, for example.

Sticking to about 10% fat on a diet plan for your dog is likely the best choice, mostly for dry matter. Moreover, “lean” dry dog foods should be less than 9% in fat content and moist foods should be below 4% in fat content. It is important to take a look at the nutrition facts before you purchase any food.

Low Fat or Low Calorie?

Sometimes, it’s not the fat content that you should be targeting and focusing all your attention on. Ideally, what you want to feed to an obese dog should be 250 to 300 calories per 8 oz. Higher calorie foods should be fed in smaller portions or controlled so that your dog doesn’t strain on those calories and have a quicker potential of obesity.

For a dog (or human) to lose weight, it has to be in a calorie deficit at the end of the day (there are some online calculators); regardless of what these calories are made up of like that last part is more about health than weight.

Additionally, if you are buying on bigger bulks of dog food, make sure it has less than 3,100 kilocalories per kg (dry food) and less than 900 kilocalories per kg (wet food). This is a rule of thumb for avoiding too dense dog foods.

More Protein For Better Weight Loss

Putting 30% or more protein in your dog’s daily meals actually helps in faster weight loss. Satiety (a.k.a. feeling full) will most likely take place with dogs on a high protein diet, leading to less chow time. Dogs and humans also both lose muscle mass when going on a strict diet, so they must replenish with protein-rich foods.

While fiber is a more popular way to induce satiety, some experts like it better when the feeling of fullness comes from high protein products.

What to Avoid

Because low-fat diets are becoming a craze to both humans and pets alike, some companies tend to reduce on resources and budget by giving you unhealthy and rushed ingredients of low quality.

Here are things you need to avoid when choosing the best low-fat dog food:

  • Preservatives, such as BHA and BHT
  • Artificial flavorings, such as dyes and coloring
  • Animal fat that has not been indicated
  • Fillers that are not necessary for the dog food
  • Regular or processed vegetable oil
  • Horrible leftovers from a slaughterhouse
  • Trimmings of fat
  • Anything else that is not natural

You want to keep the quality of each ingredient high to not just focus on the final calorie count, but also on how nutritious the meal will be for your dog. Macronutrients matter for weight loss but micronutrients matter for a dog’s overall health.

Cons of Weight Control Dog Foods

Still, many people believe that, like all foods in excess, too much low fat dog food for Fido can be bad as well. It is still good to check with your vet if your dog’s new fat-reduced diet might threaten your dog’s health. Low-fat dog food may work for normal dogs with regular diets but may have some adverse effects on pets with underlying health issues.

Dogs have been domesticated for such a long time that their digestive system has adapted to a human-like diet instead of a high-in-protein diet they had when still in the wild. Therefore, too many proteins to compensate a lower fat content could cause kidney problems in the long run.

Good and Bad Cholesterol

In humans, cholesterol exists in two sides: good and bad. The bad cholesterol, or LDL cholesterol, is what we want to avoid because it blocks arteries while the good cholesterol, or HDL cholesterol, is what we want to take to help with removing the bad cholesterol from our body, thus reducing the risks of heart diseases.

However, canine cholesterol is mostly the good onethe HDL cholesterol. Indeed, the canine’s digestive system is much better than ours at metabolizing dietary cholesterol into the good HDL type. So dog owners can relax and not worry about it.

What About Dog Treats?

Calories, carbs, fat, and protein content should be observed just the same for dog treats. Only 10% of your pet’s daily meals should be comprised of dog treats, which are usually calorie-packed. Dog treats are cheap so expect horribly processed carbs and fats as main ingredients thus making them high in calories and low in health benefits.

When you know the calorie content of the dog treat, make sure you balance it with your dog’s regular meals. For instance, if your dog treats contain a lot of calories, lessen your dog’s regular food. Always have a dog treat pouch filled with tasty goodness but pay attention to what’s inside because it’s still food that is being digested by your pooch.

Avoid these Foods

You should also watch for the following human foods and don’t give them to your canine friends:

  • Ice cream — Ice cream contains lactose, which may not be easily digested by your dog. Go for frozen yogurt instead. Calcium helps strengthen your dog’s bones, probiotics promote healthy bacteria for better digestion and protein helps your dog stay fit by burning fat faster.
  • Almonds and Macadamia nuts — Both these nuts may block the esophagus of your dog or increase water retention. They may also affect the nervous system of your dog. Give peanuts and peanut butter instead – they are rich in protein and various vitamins respectively.
  • Hotdogs and Bacon (in moderation) — Human food is for humans! And dog foods are specially formulated for dogs. These human foods may be too much for your dog so consider giving them in moderation.

Anything you would fry for yourself should obviously be avoided regardless of your dog’s diet, low fat or not. Keep the foods and meals you give to your dog as plain and simple as possible and do not use any salt, condiments, or sauces. Use some dog food toppers to enhance the taste if need be.

There is no “right” way of lowering your dog’s obesity – every single dog breed is different in its eating habits. Some dogs are picky eaters while some naturally eat voraciously. While low-fat dog food may not cater to all dogs in the world, it will surely be a great addition to your dog’s journey to weight loss.

Remember those key factors to pick the best low-fat dog food the next time you shop for Fido’s treats or meals so that you don’t compromise his health and well-being. For those only giving their dogs homemade meals, here is a video of a home-prepared recipe.

    You have got to be kidding! Almost every one of these foods have countless recalls and/or have lawsuits against them regarding false advertising their ingredients on the label, Rachel Ray, Blue Buffalo and Wellness! Most of the others aren’t sourced from the USA. What about Fromm Weight Management or their food for less active dogs. And Acana/Origin weight management?
