We all poop, it’s a fact of life. Ask most dog owners the biggest downside to having one, and you’ll probably get the answer, “cleaning up after them.”

Cleaning up after us is something that becomes second nature to our parents, something that isn’t given much attention. That is until it starts to change. As dogs, we are creatures of habit, and that includes when we do our business. Because of that, our intuitive parents are often quick to notice even the slightest change.

As we grow, our bodies change. Something that has been working for us can no longer be right. A change in our bowel movements could be an indication that something is happening, and while there are many possible reasons, one of the most common is our food.

It’s not unheard of that we become intolerant of the food that, up until a certain point, has been treating us well. It may be time for a change, and that change might need to be to a low residue food. For most people, that opens up an entirely new world of dog food. Because it can be a little overwhelming, I’ve put together the seven best low residue dog foods for less poop and better digestion.

Why Your Dog Might be Pooping More

Why Your Dog Might be Pooping More

As disgusting as it may seem to some, a dog’s poop is one of the easiest ways to monitor their health. Any change, however slight, in frequency or consistency could be an indication that something is going on. It’s important to understand the reasons behind why your dog may be pooping more so that you can determine whether or not a low residue dog food is right for them.

  • Diet – A dog’s diet is the most common reason that they may be experiencing changes in their bowel movements. As dogs grow and get older, their dietary needs might be changing, and it could be time to change their food to accommodate their needs. A food that was good when they were young might not be the right fit as they get older. 

As with humans, dogs can get simple upset stomachs that can often be traced to them eating something that is not approved by their owners. Before experimenting with different dog food, first eliminate anything else that they may be eating that they shouldn’t be.

  • Stress – Stress is another common reason for changes in a dog’s poop. While it can be difficult to pinpoint why your pup might be experiencing stress, it is something that should be addressed before changing their food. Look for other signs like anxiousness, restlessness, or nail-biting that usually go hand in hand with stress in a dog.
  • Illness – Like people, dogs can get stomach bugs and general sickness. These bugs will normally resolve themselves in a couple of days. If they don’t, it is a good idea to take your pup to the vet for a checkup to make sure that it isn’t anything more serious like parasites or bowel disease.
  • Medications – If your pup has recently been to the vet and given medication, this could very well be the cause of their change in bowel movements. It’s very common for antibiotics to cause an upset stomach, especially if you are having a hard time getting them to eat with those antibiotics.

If this is the case, contact your vet as they will probably need to adjust the dose of the medication or change it completely.

What is Low Residue Dog Food

The word residue refers to ingredients in a dog’s food that may be harder to digest and, therefore, lead to more poop. Simply put, a low residue dog food reduces fiber by eliminating some of these ingredients that can be hard to digest like grains, corn, and wheat.

As your dog gets older, you may find that they are having a hard time digesting some of the residues in regular dog food. By switching to a low residue food, you will lower your pup’s intake of these ingredients and, in turn, make the food easier on their stomach and reduce the amount of poop.

Less waste moving through your pup’s digestive system will also reduce the internal stress on the body. While this may not be as big of a concern for young, healthy puppies, it can be extremely important for older dogs, or dogs with health problems.

Low residue food is typically intended as a short-term solution to solve digestive issues but can be used as a long-term fix as well. It is important to consult a vet throughout the entire process to help determine whether your pup can be transitioned back to regular food or need to stay on a low-residue diet.

The Benefits of a Low Residue Diet

Reducing poop can benefit both the dog and the owner. The less mess the better, right? But that’s not the only benefit.

  • Better Pancreas Health – The function of a dog’s pancreas is the same as that of a human; it breaks down food and regulates sugar levels. Dogs that have lowered pancreas function or pancreatitis can benefit greatly from a low-residue diet.
  • Better Colon Health – Colitis is a condition where a dog’s colon can become inflamed. Because a low residue diet leads to better digestion, it can also mean that it is easier for them to excrete their waste and, therefore, reduce inflammation in their colon.
  • Eases Both Diarrhea and Constipation – Another benefit to a low residue diet and improving digestion is the ease of both diarrhea and constipation. Food is broken down easier, making waste more consistent and easier to pass.
  • Reduces Foul Gasses – A byproduct of poor digestion is flatulence. The foul-smelling gas your dog may be producing is due to the inability of their colon to effectively remove all of the waste they have built up. A low-residue diet will help to ensure that there is no waste left trapped in the colon and in turn reduce gas.

What to Consider When Looking for a Low Residue Dog Food

Looking for a Low Residue Dog Food

Just like any other dog food, low residue foods are not all created equal. If it’s time to put your pup on a low residue diet, there are a few things to consider when trying to find the right food.

  • Low Fiber Content – The idea behind a low residue dog food is to produce better digestion by reducing hard-to-break down fiber ingredients like corn, wheat, and grains. The right food should be much lower in fiber than regular dog foods and contain fruits and vegetables as their source of fiber, as they are much easier for your dog to break down.
  • Protein – Protein is an important part of any dog’s diet, maybe even more so for a dog on a low residue diet as it can make up for the lower-fiber content. Not only is the protein count important, but so too is the source of that protein. The protein source should provide the right amount of energy while remaining easy to digest. Look for ingredients like whole meat or meat meal that specify exactly what the source of that meat is, whether it’s chicken, beef, or pork. Knowing exactly what animal the meat is from will reduce the chance of the food having ingredients that may have more detrimental side effects.
  • Allergen-free Ingredients – Dogs are just as susceptible to allergies as people are, and those allergies could be one of the reasons why your pup has poor digestion. If this is the case, it is important to determine what your pup might be allergic to, which could sometimes feel like searching for a needle in a haystack. With that being said, there are ingredients that dogs are more prone to being allergic too like corn, wheat, and even meat like chicken and beef. It’s important to avoid artificial flavors and colors, as well as meat by-products, as these are ingredients that can easily trigger allergies and digestive issues in many dogs.
  • Digestibility – Not all food manufacturers will list the digestibility rating on their labels. A low residue should be easily digested, but it’s not always easy to find the right information about its digestibility rating. Finding food that displays this percentage on the label is the easiest way to go about it, but it might involve a bit of research. An easily digested food should have a digestibility rating of 80% or higher.
