Best Dog Probiotic Supplements for Improved Digestive Health

Probiotics are live bacteria and yeast that help keep your pet’s gut healthy. Just like in people, dogs rely on the good bacteria in their digestive system to break down food and absorb nutrients. Adding a probiotic supplement can support your dog’s digestive health, especially if your pet has stomach issues, has taken antibiotics, or is stressed.

Dog probiotic supplements come in many forms, including powders, chews, and capsules. The right supplement may help with issues like diarrhea, upset stomach, and even bad breath. We also found that some products include extra ingredients such as prebiotics, enzymes, or vitamins to support overall health.

When shopping for a dog probiotic, it’s important to check for the number and type of live bacterial strains, the overall CFU (colony forming units) count, and whether the product is made for your dog’s size and age. It’s also a good idea to look for third-party testing and clear labeling to know what you’re giving your dog. We spent hours researching and reviewing popular dog probiotic supplements to find the best choices for most pets.

Best Dog Probiotic Supplements

We have researched and reviewed top dog probiotic supplements to help support digestive and immune health in dogs. Below is our list of the best options you can buy right now.

Purina FortiFlora Dog Probiotic Powder

For dogs with sensitive stomachs or digestive troubles, this is a practical probiotic solution that’s easy to use and seems to work well.

Pros

• Noticeable improvements in digestion and stool quality
• Easy to sprinkle on any food, mixes in seamlessly
• Helps support overall immunity and reduces gas

Cons

• Sachets run out fast, so frequent repurchasing is needed
• Some dogs may not enjoy the powdered taste
• Price is on the higher side compared to similar products

We were able to introduce FortiFlora to our dog’s meals without any fuss. The powder format easily blended with kibble or wet food and didn’t seem to change the flavor much, at least from what we observed. Cleaning up after our dog became easier soon after starting regular use, with fewer stomach upsets and more regular stools.

What stands out is how quick it is to add into a daily routine. We appreciated that there was no struggle to get our dog to take it. It was also reassuring to see a decline in unpleasant gas, which made time indoors much more comfortable for everyone.

One thing to watch out for is the number of packets in the box—they won’t last long for multiple dogs or long-term use. While the supplement is effective for tummy issues, the cost can add up over time. For dog owners looking for reliable digestive help and willing to invest, FortiFlora is a straightforward pick.

PararaPets Dog Probiotic Soft Chews

If we want to improve our dog’s digestion and support their gut health, these chews from PararaPets are a helpful option.

Pros

• Noticeably helped with our dogs’ stomach problems
• Pork flavor makes them easy to give as a treat
• Suitable for any size or breed

Cons

• Chews may be too soft and can crumble
• Only one flavor option available
• Jar takes up more space than a small pouch

Our dogs took to PararaPets Probiotic Chews immediately thanks to the appealing pork taste. We noticed a real shift in their digestion within a few days, with less gas and firmer stools. Giving the chews as treats made supplementing their routine very simple.

One thing we appreciate is that the chews work for different breeds and weights, so we didn’t have to buy separate products for each dog. The included dosage guide was clear and easy to follow. The large tub lasted for quite a while, which was convenient.

The texture is soft, which made them easy to chew, but we did see some pieces break apart in the jar if handled roughly. Still, we’re pleased with how well these chews supported our dogs’ digestive health and believe they’re a solid choice for managing occasional tummy issues.

Zesty Paws Probiotics Soft Chews

If we want to support our dog’s digestive system with an easy-to-feed, tasty treat, this probiotic supplement feels like a practical choice.

Pros

• Dogs seem to love the soft, chewy texture and pumpkin flavor
• Supports digestion, especially for dogs with sensitive stomachs or occasional gas
• Convenient to give without messy powders or pills

Cons

• Results can be subtle and might not be noticeable right away
• Some dogs may not see big improvements in all symptoms
• Chews can harden if not stored at room temperature

When we tried these Zesty Paws probiotic chews, our dogs thought they were getting a special treat, not a supplement. The pumpkin flavor actually seems to make a difference, especially for picky eaters. It took only a few days before we noticed some improvement in digestion, and we didn’t have to hide the supplement in their meals.

We found it reassuring that each chew has several types of probiotics and uses a clinically studied strain for gut health. It was easy for us to remember to feed these each day, and the chews didn’t leave a mess behind. Our dogs’ stools stayed firmer, and there was less gassiness, which makes sense for a product focused on digestive support.

However, don’t expect overnight changes. For some of us, it took a bit longer to notice steady improvements, especially with older dogs or those with ongoing tummy issues. The chews can get a little hard if stored in the fridge, so we kept them in a cool pantry instead. Overall, Zesty Paws Probiotics Soft Chews offer a convenient way to help our dogs’ stomachs feel better without any fuss.

PetLab Co. Dog Probiotic Chews

If we want to help with our dog’s itching, allergies, or sensitive stomach, using these chews might make a noticeable difference in a few weeks.

Pros

• Many dogs like the pork flavor and eat the chews easily
• Can help with itchy skin and paw-licking
• Some owners see better digestion and less diarrhea

Cons

• Does not work for every dog, especially picky eaters
• Results may take several weeks to show
• Soft texture can sometimes crumble in the container

We have found these probiotic chews from PetLab Co. to be simple to give each morning. Many dogs accept them as a treat, which means less hassle for us. The pork flavor has been a hit in most cases, so there is less struggle during pill time.

After a few weeks of daily use, there’s been a clear improvement in our dog’s comfort. There’s less scratching, and the licking of paws slowed down. Dogs with upset stomachs or loose stools have shown improvement, which makes our daily walks less stressful.

However, not everyone will get the same results. We noticed it can take more than a month to see clear changes. Dogs that are especially picky may refuse the chew altogether, and sometimes the soft chews stick together or break apart in the container. Still, with regular use, these probiotic chews are worth trying if we want to support our dog’s digestion and skin health.

Nutri-Vet Pre & Probiotic Soft Chews

If you want a simple way to help your dog’s digestion daily, these Nutri-Vet chews could be a smart addition.

Pros

• Tasty flavor most dogs will eat willingly
• No powder or mixing, just a soft chew
• Helps with stool quality and tummy issues

Cons

• Some picky dogs refuse them after a while
• Packaging may not keep chews fresh
• Effects can be subtle in some pets

Giving these chews a try with our dogs was easy since they seemed to enjoy the liver and cheese taste right away. It was a relief not to deal with messy powders or extra steps at feeding time.

We noticed less stomach upset and more solid poop for several days after starting these supplements, especially in dogs that usually have sensitive stomachs. It’s helpful that each chew offers a blend of prebiotics and probiotics, and the vet-formulated recipe adds confidence.

On the downside, one or two of our pickier eaters eventually got tired of the flavor, so consistency could be a challenge. Another issue we had was with the packaging—sometimes the chews dried out before we finished the container. Overall, these chews make it easier to support our dogs’ gut health, but taste and freshness can vary.

Buying Guide

When choosing a probiotic supplement for our dogs, we should look at the type and number of probiotic strains. More strains often means better gut support, but too many is not always needed for all dogs.

We should check the ingredient list for fillers or artificial additives. Short, simple ingredient lists are usually better. Looking for products made with natural and simple ingredients can help avoid unwanted side effects.

It’s important to check the CFU count (colony-forming units), which shows how many live bacteria are in each dose. A daily dose should usually be in the millions to billions.

Product Form Comparison

Form	Easy to Use	Good for Picky Eaters	Shelf Life
Powder	Yes	Yes	Medium
Chews	Yes	Often	Medium
Capsules	Sometimes	No	Long

We must also think about our dog’s needs, such as age, size, and health. Some probiotics are made for puppies, seniors, or for dogs with allergies.

Looking for products that have been tested by third parties can give us extra peace of mind. We can usually find this listed as “third party tested” or “quality checked” on the label.
