What Are Dog Probiotics?

Probiotics are supplements that contain billions of beneficial bacteria that help balance out the bad bacteria in the stomach that tend to cause digestive issues. When ingested, this bacteria can colonize in the digestive system and balance the gut flora. Dog probiotics can decrease flatulence, diarrhea, and other gastrointestinal issues, making them great for dogs with regular or occasional tummy troubles.

That said, it's believed that digestive health and healthy gut flora can play a role in overall health, so a daily probiotic can be beneficial even if your dog isn't suffering from digestive complaints. Additionally, the Association of American Feed Control Officials (AAFCO) approves probiotics for dogs as both a digestive and immune system support supplement. But always check with your vet before giving your dog something new.

When looking for a probiotic for your dog, look for one with several strains and multiple colony-forming units (CFUs), or the number of bacteria, for the best variety. It's also important to store these supplements properly, as the bacteria is alive and exposure to air, moisture, or temperature extremes will damage their viability. Each brand may have a different recommendation on storage, so read the fine print closely.

Frequently Asked Questions
Can dogs take human probiotics?

No. Humans and canines are not the same species and are not the same size. Daily recommendations are based on weight and humans are often larger than dogs, which is why smaller doses of canine probiotics are recommended.

Is it okay to give my dog probiotics daily?

Yes, it's fine to give your dog a daily dose of probiotics to maintain gut health. Read the recommendations from the brands and consult a vet if you're treating a chronic digestive issue or trying to replenish gut flora after a course of antibiotics.

How do I give my dog a probiotic?

There are several kinds of probiotic forms that are ingested differently. Powders and liquids can be mixed with food, capsules can either be opened and mixed with food or fed whole, and soft, flavored chews can be taken as regular dog treats.
