What is a low-fat diet, and when do Dogs need it?

Society has ingrained into us that fat is unhealthy and linked to heart disease and obesity. So indeed, it’s the same for our dogs? In fact, canine nutrition is very different from humans; fats are an essential nutrient and should make up a healthy portion of their diet. Fats are an excellent energy source and are necessary for absorbing many vitamins and nutrients. So why do some dogs need a low-fat diet?

When we think of the term ‘low fat’, the thing that comes to most peoples’ mind is weight loss. But for dogs struggling with weight, there are many other, more effective ways to get them to shed the pounds. Low-fat diets are more commonly used to help manage certain health conditions that benefit from restrictive fat diets. These health conditions include:

• Pancreatitis
• Exocrine pancreatic insufficiency (EPI)
• Lymphangiectasia

So, what are they, and why does fat restriction help?

Pancreatitis is the most common health reason which requires fat restriction. It is a severe disease where digestive enzymes are prematurely activated before leaving the pancreas, leading to inflammation, bleeding, and destruction of the organ. The most common symptoms are severe abdominal pain, vomiting, and diarrhea; however, in some cases, it can also lead to organ failure and death. Pancreatitis can be triggered by many causes, including high dietary fat content. If your dog is being treated for pancreatitis, he needs this diet. Also, dogs who have had pancreatitis in the past may be prone to developing it again, and therefore should be managed on a low-fat diet long term.

Exocrine pancreatic insufficiency is another condition relating to the pancreas which benefits from a low-fat diet. This is a condition where the pancreas does not synthesize or secrete digestive enzymes, resulting in loss, fatty feces, diarrhea, and hunger. Supplementation with digestive enzymes can improve the symptoms, but even with enzyme supplementation, fat is still not absorbed into the blood properly, leading to fatty feces and diarrhea. This diet can help with this, although this should be carefully monitored if it is too low, not enough fat-soluble vitamins will be absorbed, and the symptoms will worsen if it is too high.

Finally, lymphangiectasia is also a condition that benefits from low-fat food. It is commonly confused with inflammatory bowel disease. However, it is a different condition. Nonetheless, they can occur concurrently. Lymphangiectasia is a condition with no known cause and results in dilating a part of the intestine walls, known as the villi. Symptoms include protein loss (leading to fluid build-up in the abdomen and lungs), vomiting, diarrhea, and weight loss. Unlike EPI, a low-fat diet reduces diarrhea associated with poor fat absorption into the blood.

So, these diets can benefit several health conditions, but are they helpful for weight loss?

In people, low-fat diets are wonderful at aiding weight loss, but in dogs weight loss can be achieved more successfully with other methods. Nevertheless, these diets can aid to some degree in managing obesity, so in combination with other efforts, your pet can effectively fight the extra pounds with a diet change. Some ways to help reduce weight include:

• Feed your dog according to his ideal weight and not his current weight, as detailed on your food packaging.
• Feed two structured meals per day instead of allowing your dog to graze on food.
• Increase an exercise by taking him for more walks long walks, or dedicating some time to playing with him in the garden.
• Reduce or eliminate threats, and remember treats equal calories, so remove the equivalent amount of food from his daily meals.
• Switch to a low calorie, high satiety food, so he feels fuller even though he’s getting less.

When it comes to considering a low-fat diet for your pet, whether it be to treat an underlying condition or complement your efforts to get him to lose weight, you should always consult your veterinarian first. Fat is not unhealthy, and in fact, contains many essential nutrients such as omega oils, so reducing fat intake is not always the answer.

Buying Guide

If you’ve discussed things with your veterinarian, and you are both in agreement that a low-fat diet is the most suitable for your dog, you might decide which low-fat food to choose? Choosing a new dog food can be daunting, and you are likely to be faced with many choices. The label is a good starting point to help you make your decision.

• Firstly, look at the guaranteed analysis. This is a table on the back of the food packaging which tells you how much fat, protein, fiber, moisture, and ash are in the product. However, this is based on the ‘as fed’ values and not on a dry matter basis, so you need to do some math to work out how much fat there is in the food. For example, if the moisture content says 10%, that means the dry matter content is 90%, which we want to convert to 100%. So, if the crude fat measurement says 8%, to calculate the actual fat percentage on a dry matter basis, all you need to do is divide 8% by 0.9 (90%), or in other words: 8% / 0.9 = 8.88% fat on a dry matter basis.
• Now you can compare dog foods to each other. If your pet needs low-fat food due to pancreatitis, the lower the better. Some veterinary prescription foods have a very low percentage of fat, and these are the best to go for in this situation. However, if you are simply trying to get your dog to lose some weight or manage the fatty diarrhea symptoms of EPI or lymphangiectasia, providing some fat is important to absorb vitamins into the blood. Therefore, food in the middle or higher end of the low-fat range is better. This food is generally considered containing less than +/- 10% fat on a dry matter basis, and the lowest it is likely to be is around 4%.

So now, you can choose the food with the appropriate fat content for your dog. But you might still be left with a few to pick from. How do you know which one is the right one? Here are some tips for things you should look at on the label:

• Nutritionally balanced. This is the most important thing to consider. Since removing fat will remove some nutrients, additional ingredients need to be added to ensure it is a nutritionally balanced and complete diet. Otherwise, your dog may end up with nutritional deficiencies. The packaging should have a statement printed on it that says it conforms to nutritional adequacy standards as set out by the AAFCO, and it has tested its food to prove this.
• Lifestage. Foods may be formulated for the average adult dog, but some foods are specifically formulated for different life stages, such as junior or senior years. If your dog falls into one of these categories, it might be a better choice than standard food.
• Ingredients. The ingredients are listed in order of fresh weight. Therefore, the first on the list has the highest content. Meat proteins should be high on the list, and the list should not have excessive refined carbohydrates on it, such as maize meal or white rice.

If you’re still unsure about your decision after looking at the label, researching consumer reviews is invaluable. The manufacturer can make plenty of claims; however, hearing first-hand how the food affects consumer’s dogs can give you some valuable insights into the palatability and the quality of the food.

Finally, all food manufacturers have it in their interest to put your mind at ease. You can always pick up the phone and talk to them directly if you have specific questions about their product which you can’t seem to find answers for.
