Digestive aids for dogs help improve your pet’s gut microbiota and overall intestinal health. Supplements include probiotics, prebiotics, digestive enzymes, and vitamins.

Most of the health supplement industry is nonsensical due to low standards of regulation from the FDA. While most intestinal supplements won’t hurt your dog, only a few will actually benefit your pet’s gut health. Additionally, each supplement type will have its own way of positively impacting the dog’s overall health.

Make sure you read all of this article and browse our product reviews below.

What do digestive aids for dogs do?

Dog digestive aids are designed to mimic the normal digestion and clean the digestive tract in dogs by use of various supplements. Such assistance is particularly needed when digestion has become perturbed or interrupted due to poor gastrointestinal health. The digestive system’s key role in the overall health is to absorb nutrients from food and assimilate them throughout the body for nourishment. The lack of intestinal motility and ability to break down particles of food to ensure cellular survival may be due to a wide range of causes and factors. Understanding the cause of a dog’s digestive inconsistencies is ideal to know how to treat it.

There are a number of effective intestinal aids for dogs on the market, all with their own function and role. Many common digestive problems include flatulence, diarrhea or constipation, nutritional deficiencies, and indigestion. If these problems aren’t fixed, they can lead to more serious health complications.

Digestive supplements for dogs assist in strengthening your dog’s immune system. Over time, they help promote a healthier gut microbiota (interesting study here). Digestive aids for dogs provide unprecedented value to your dog’s life so it helps to know which of these helpful elements are needed for your dog’s overall improvement, as well as the role they each play.

What are the different types of dog digestive aids?

Dog digestive aids primarily work to help digestion through supplemental remedies such as probiotics, prebiotics, digestive enzymes, or other herbs to help soothe and support your dog’s overall gastrointestinal health and ensure firmer and overall better stools.


Dog probiotics are live, active cultures and microorganisms that are generally found in certain foods and dietary supplements that assist the gastrointestinal tract by providing beneficial bacteria. This is the term used to describe the many beneficial bacteria and yeasts that reside in the gut. Just as there are bad bacteria, there is also good bacteria. The body needs these. Probiotics help fight off unwanted pathogens in the dog’s digestive tract and improve the functioning immune system. A good digestive aid for dogs would be one that thoroughly aids the natural function of the intestine, but also enhances its power. That’s what probiotics do.

Often time, stress and illness will wipe out some of the beneficial gut flora and seriously wreak havoc on your dog’s overall health system. Probiotics for dogs are normally used during times of extreme stress, a bacterial imbalance or infection, old age, abrupt changes in the diet, parasites, or even some types of medications. These beneficial bacteria can be found in yogurt and kefir, capsules, in powder form, specialized dog foods, or chews. Always check ingredient lists and look for cultures like Lactobacillus acidophilus, Bifidobacterium lactis, Lactobacillus, and Bifidobacterium. They really work wonders on your dog’s digestion.

Dog prebiotics are very similar to probiotics but still retain their unique function in the overall digestive system in dogs. Prebiotic fibers help clean the tract and bulk up the dog’s stools.

These digestive aids for dogs are actually nondigestible food ingredients that benefit the organism by stimulating the growth of the beneficial bacteria in the gut. In other words, prebiotics nourish the probiotics, therefore, they actually work hand in hand to ensure optimum digestion and health. These are a type of fermentable and soluble fiber and when combined with probiotics in a given supplement or food they are termed “symbiotic”.

Due to the fact they work in a synergetic relationship with probiotics, prebiotics for dogs promote viable bacteria to grow in the gut and ensure proper digestion, thus, leading to less risk of disease, enhancing the immune system, and also assisting in nutrient absorption. Dogs fed a regular diet of prebiotics tend to suffer less from diarrhea as the soluble fiber absorbs water and slows down the gastrointestinal transit. In the colon, they are fermented by the bacteria into short-chain fatty acids and are great for dogs who have undergone intense antibiotic therapy as well as reducing the risk of irritable bowel disorders and colon cancer.

Digestive Enzymes

Digestive enzymes for dogs are a group of macromolecular biological catalysts that help break down foods in the dog’s digestive tract to facilitate more complete absorption of the nutrients eaten. Digestive enzymes are special proteins that are responsible for an array of functions in the body. There are three main digestive enzymes in a canine’s body. The Protease enzyme helps break down proteins into the amino acids. The Lipase enzyme assists in breaking down fat into glycerol and fatty acids. And the Amylase enzyme breaks down the carbohydrates into sugar.

Most of these enzymes are produced in the pancreas and then get distributed into the small intestine. From here, the breakdown proceeds and the particles are then used for cell production and fuel. Pancreatic enzymes for dogs help the body break down fats, carbohydrates, and proteins.

Some foods are often replete with digestive enzymes as well such as the beta-amylase in fruit. In addition, enzymes work to support the immune system, remove bodily toxins and waste, helps regulate hormones, slow the rate of aging, and even reduce inflammation. These functions are all maintained with the added help of coenzymes, vitamins, and minerals. Without enzymes, the body would naturally cease to function properly and the body would suffer from nutritional deficiency as well as enzyme deficiency.

Vitamins and Herbs

Digestive aids for dogs come in various shapes, sizes, and varieties and it doesn’t stop here. In addition to the probiotics, prebiotics, and enzymes that are normally revered for digestive support, vitamins play an important role. Dog digestive aids in the form of vitamins can come from foods such as those which are found in dog dry foods and canned, additional supplements, or be given in liquid form depending on your preferences and whether or not your dog is ingesting them without issues. Vitamins are very crucial as they serve as digestive co-factors in a dog’s diet. These co-factors are required for enzymes to function properly. One important vitamin to consider is the B12 which aids digestion.

If your dog’s diet is not providing a sufficient amount of nutritional value then it’s up to you to administer vitamins so that they can benefit greatly from these supplements. These can be in the form of a multi-vitamin as most of the vital elements are produced in one serving. It’s rather difficult to fulfill all your dog’s micronutrient needs, in this way, a multivitamin can serve to fill the void. Moreover, another great idea is to look around for herbal remedies. Herbal supplements are more natural and provide an easier transit in your dog’s digestive system as they are less aggressive.

Top 5 Best Digestive Aids for Dogs

For dogs to have a healthy digestive system, their diet should contain highly digestible nutrients, minerals, vitamins, and trace elements. Because it is hard for most dog owners to provide everything a dog needs from their diet, using digestive aids makes sense.
