Dogs primarily “see” their surroundings with their nose – meaning, they process information based more on what their olfactory receptors send to the brain than on what their eyes see. In short, sniffing things they come upon is the way of life for dogs. They sniff and explore, and more often than not, eat whatever they find – dirt, paper, stone, grass, dead animals, spoiled food, poop or anything else. If your dog habitually does this, your shopping list may need to include the best digestive aids for dogs to solve your pet’s tummy issues.

Digestive aids for dogs have become very popular among pet owners, and there are many to choose from on the market. We’ve researched a number of products to find the five best digestive aids for dogs. These were the most effective, healthy and safe for pets:

Choosing the right digestive aid for your dog

Best Digestive Aids for DogsDietary indiscretion is not only gross, it can actually harm your dog. A dog can only be as healthy as the food that goes into his mouth. That’s so true, because what a dog eats is what nourishes his body.

The opposite can also be true, that is, you can tell how healthy a dog is by what comes out his other end. Dog stool should be firm but not hard, moist but never loose. Dogs need digestive support to make their guts healthier, help their system process food and absorb nutrients from them better, in order to pass healthier-looking stool.

It’s important that you do the research to find healthy and safe products. Supplements made with artificial ingredients and chemicals may help improve digestion in the short term, but they could also have harmful effects on your dog’s health in the long run.

The digestive aids on this list are made with natural ingredients that have been proven to be effective at aiding digestion. Some include beneficial microorganisms and probiotics (which stimulates the growth of these microorganisms). Research has proven that these microorganisms are imperative to healthy digestion.

Other supplements on this list include natural ingredients that have been shown to improve digestion. For example, pumpkin has been shown to be a natural remedy for upset stomach, diarrhea and constipation. Adding additional sources of natural fiber to your dog’s diet is another way to improve his digestion.

Before adding any dog supplements to your pet’s diet, be sure to consult your veterinarian or a trained canine nutritionist. A holistic veterinarian may be especially helpful when it comes to recommending the best digestive aids for dogs.
