The best dog foods for less poop are low in fiber, also known as low residue dog food. This diet is great for dogs with digestive issues, certain illnesses, or issues with diarrhea and constipation. If you think your dog might thrive on a low fiber diet, it’s a good idea to start by sharing your concerns with your vet.
If you’ve already spoken with your dog’s vet and are ready to shift towards a low fiber diet for your dog, we have you covered. This buying guide explains what low residue dog food is, outlines it’s benefits, and lays out how to choose the best low fiber food.
We’ve also reviewed seven highly rated low residue dry dog foods, ending with our recommendation for the best one so you don’t have to search forever to find the perfect food for your pup.
What is Low Residue Dog Food?
Low residue dog food is made for dogs with intestinal and digestive health problems like inflammatory bowel syndrome, diarrhea, constipation, flatulence, and frequent vomiting. The focus of low residue recipes is highly digestible, low fiber foods.
Most regular bargain brand dog food is full of ingredients like grains, corn, and wheat, which can be difficult for some dogs to digest, especially seniors. These ingredients are also common allergy triggers.
By feeding your dog a low fiber food you avoid some of these things that your dog may be sensitive to. Low residue food is easier to digest, and since your dog’s body absorbs more of the nutrients that they need less waste will come out!
Having less waste moving through your dog’s digestive system reduces some of the workload (and stress) that is put on by low quality food or other digestive upset your dog suffers from.
Some low residue dog foods contain medicinal ingredients and supplements to help heal and assist your dog’s digestive system.
The low fiber diet is usually intended for the short-term. If your dog’s symptoms are gone you can consult with your vet and maybe switch back to your dog’s regular food. Some dogs including older dogs and those with frequent or chronic digestive issues will need to stick to a low residue diet.
Making your own low residue dog food
It’s possible for you to put together nutritious, low fiber meals for your dog but it does take a little time and know-how. The Nest has a great article by Sarah Whitman that outlines the process.
First of all, you need to make sure the ingredients in your recipe are cooked, including any meat products, grains, fruit, and vegetables, so they are easier for your dog to digest.
Next, you’ll need to include some healthy oils (especially omega 3 and 6 fatty acids!). These oils serve the important tasks of slowing your dog’s digestion, helping absorb nutrients, and fighting inflammation.
As far as your recipe goes, it ideally should consist of between 50% and 80% real meat ingredients like meat, fish, and eggs. These ingredients are soft, low in fiber, high in protein, and easy to digest making them the perfect starting point for your dog’s nutrition.
The other 30% of your recipe will consist of nutritious low fiber fruits and vegetables (think ripe bananas, melons, carrots, and potatoes), healthy oils, and any other vital supplements you might need to add to contribute to your dog’s total health. The example recipe Whitman gives in her article includes:
Whether you choose to cook your dog’s food yourself or switch them to a low fiber dry food, make sure you switch them starting with small portions. It will be easier for your dog’s digestive system to adjust to this new diet gradually rather than all at once.
Soluble vs. Insoluble Fiber
Since the low fiber content is an important feature of low residue dog food, it’s important to talk about the difference between insoluble and soluble fiber.
Soluble fiber dissolves in water and is broken down in the colon, resulting in a gel-like substance. If your dog is suffering from constipation, soluble fiber will help add moisture to your dog’s stools, making them softer and easier to excrete.
A few sources of soluble fiber include oats, barley, lentils, apples, and many vegetables.
Insoluble fiber does not dissolve, but stays a solid when it passes through the gastrointestinal system. This type of fiber will help bulk up your dog’s stools, so if they are too watery, insoluble fiber can be used to help.
Some examples of insoluble fiber sources are whole wheat ingredients, whole grains, and root vegetables.
Benefits of a Low Residue Dog Food?
There are several benefits to switching your dog to a low residue dog food. While most dogs are put on a low residue food when they are older or problems have already started to develop, it can be beneficial for a puppy or adult dog to be on this type of diet as a preventative measure.
Some of the clear benefits of switching to a low residue dog food are:
1. Reduced Frequency and Volume of Stools
Most budget commercial dog foods include a few healthy ingredients along with a laundry list of fillers and artificial ingredients meant to save money, enhance the look of the food, and literally fill your dog’s stomach. The problem is that these fillers are not easy for dogs to digest. When the digestion process is hindered your dog doesn’t get all the nutrition from the food they’re eating.
2. Good for the Pancreas and Colon
Both the pancreas and the colon can become inflamed which causes various problems for your dog.
The pancreas is an organ of the digestive system responsible for breaking down your dog’s food and regulates sugar processing.
Pancreatitis happens when the pancreas becomes inflamed. A diet high in protein and healthy fats can help with the recovery process.
A case study by Christine Liu from Cornell University shows that a low residue diet has been recommended for dogs with pancreas issues for a while now. In this study, a German shepherd with exocrine pancreatic insufficiency was put on Hills LD canned and Eukanuba Low Residue dry food.
The colon is a long organ that removes water from digested food.
What is left is your dog’s stool, which passes through the colon to the rectum and out of your dog’s body. Colitis is a condition where there is inflammation of the colon.
A 1988 study published in the Journal of Veterinary Internal Medicine found that symptoms of idiopathic chronic colitis improved in a sample of 13 dogs after they were switched to a low residue, easy to digest, and mostly hypoallergenic diet.
A low residue diet should help reduce the inflammation associated with either a diseased pancreas or colon, while improving your dog’s overall digestion.
3. Helps with Diarrhea and Constipation
Diarrhea and constipation are both signs that something about your dog’s digestive and excretory system is irregular. It could be something in the food they are eating, age, or a medical issue.
The lack of fillers in low residue food encourages normal digestive processing. Since food is being properly broken down at this stage, your dog’s digestion and stools return to normal.
Switching to a low residue diet will improve the efficiency of your dog’s digestive system and the help regulate the frequency/consistency of their poops.
4. Aids in Digestion and Flatulence Problems
Flatulence occurs when your dog’s body isn’t able to process waste efficiently.
Fibrous foods are hard for some dogs to digest, which is why low residue dog food is designed to ensure that the food passing through the digestive tract is fully broken down. This eases the strain on your dog’s gastrointestinal system.
Since less waste is passing through the digestive system, there is less stress on the system and your dog’s symptoms will get a chance to improve.
How to Choose the Best Low Residue Dog Food?
Choosing the best low residue dog food is easy when you know what to look for. Two main things you want to consider are:
1) the overall quality of the food and 2) whether it meets the criteria to be considered low residue.
Unfortunately, like many other special diets dogs, it can be hard to distinguish when a brand is truly putting dogs’ health first or just using popular marketing terms to create hype and sell more sub-par food.
Even if you find a brand that’s labelled ‘low fiber’ or ‘low residue’, make sure you do your due diligence!
You can take some of the guesswork out of the process with this handy checklist that explains what’s important in a low fiber/low residue food:
If you’re considering a low residue food for your dog and it ticks off all of these boxes you’re good to go!
Remember to slowly wean your dog off their old food (if they were on a different food before). It may still take some trial and error to find a formula or recipe that your dog finds palatable and agrees with their digestive system.
