Top 5 Best Digestive Aids for Dogs


– There are lots of digestive aids available in the market that contain natural ingredients beneficial to dogs

– Dogs should be able to produce the enzymes and healthy bacteria that naturally help their gut health

– Do not self-medicate your dog; consult with your veterinarian or a trained canine nutritionist before giving the best digestive aids for dogs

Dogs sniff and explore and often 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.

They've been used and vet-recommended for GI issues, sensitive stomach, dietary problems, and anal glands in dogs.

But a word of caution: don't just give these to your dog without your vet's approval.

Dr. Hannah Godfrey, BVetMed, MRCVS, says, “Your dog’s body should produce everything that they need in the right amounts, and supplementing with extra enzymes could cause a stomach upset or even ulceration of the mouth. If you’re concerned that your dog isn’t digesting their food well, or they have any symptoms, speak to your veterinarian for advice.”

Self-medicating may just do more harm than good so let's not go down that route!

In this article, we've listed 5 of the best digestive aids you can ask your vet to give Fido when he has upset stomach.

We've also included a short buying guide as to how you can choose the right one for him.

Without further ado, let's get started!

Choosing the Right Digestive Aid for Your Dog

Dietary indiscretion (aka feeding on unusual items like garbage, poop, etc.) is not only gross, but it can also harm your dog.

Remember that a dog can only be as healthy as the food that goes into his mouth.

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.

They 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.

And as pet owners, it's important that we do the research to find healthy and safe products for our pooch.

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.

So the digestive aids I've included on this list are made with natural ingredients that have been proven to be effective at aiding 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.

Some include beneficial microorganisms and probiotics (which stimulate the growth of these microorganisms).

Research has proven that these microorganisms are imperative to healthy digestion.

And again, 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.

5NaturVet No Scoot Plus Pumpkin Soft Chews
by NaturVet

Dogs scoot or drag their butt on the ground when something bothers them in their rear.

It could be extreme itching or pain, but the most common reason is anal gland infection.

NaturVet No Scoot Plus Pumpkin Soft Chews, the last of the best digestive aids for dogs on this list, can be the solution for what ails these dogs.

These good dog digestive aids contain a dandelion root, pumpkin powder, and a proprietary blend of beet pulp, flaxseed, and psyllium husk.

The combined effects of these active ingredients normalize digestion, improve digestive tract health, and enhance anal gland functioning.

Some dog owners resort to bringing their dogs to the groomer for manual expression of the glands when they notice scooting.

These glands are actually very sensitive, and manually expressing them could cause more harm than good.

The best way is to use the dietary approach, which is good but can be quite tedious if you home-cook everything.

A more convenient way is to add supplements like NaturVet No Scoot Plus Pumpkin Soft Chews to your dog’s food regimen.

Ingredients: Active Ingredients Per 2 Soft Chews: Proprietary Blend of Sugar Beet Pulp, Flaxseed and Psyllium Husk 1000 mg Dandelion Root 50 mg Pumpkin Powder 16 mg Inactive Ingredients: Brewer's dried yeast, canola oil, citric acid, deionized water, glucerine, lecithin, natural flavoring, natural mixed tocopherols, potato starch, rosemary, sorbic acid, tapioca starch, and vegetable oil
