Take your dog’s health and comfort to the next level with our tailored probiotics for dogs. These tasty, pork-flavored soft chews have been clinically studied to enhance a balanced inflammatory response in the gut1. Formulated with prebiotics, probiotics, and postbiotics to promote dog gut health, help maintain healthy yeast levels, and support seasonal allergy discomfort.
Good Bacteria Gets to Work
Our easy-to-give probiotic supplement for dogs contains a proprietary blend of probiotics designed to maintain healthy gut flora, support the immune system, and help normalize your dog’s bowel movements. Additionally, prebiotics and a postbiotic blend of yeast helps maintain normal canine digestive function and help support dogs with occasional stress.
Designed to Maintain Gastrointestinal Health
If your dog deals with occasional loose stools, soft poop, or periodic digestive discomfort, daily consumption of these soft probiotic chews for dogs may reduce gas and help dogs sustain normal stool consistency and bowel movements.
Powerful Yeast and Seasonal Allergy Support
No pet parent wants to see their dog paw licking, head shaking, biting, and scratching. The prebiotics and probiotics in this soft chew support healthy immune function in dogs, which can lead to a better response to seasonal allergy discomfort and support healthy yeast levels.

Why Millions of Dog Owners Have Chosen PetLabCo.®
Frequently asked questions
Consult with your veterinarian if you’re wondering how long to keep your dog on a particular supplement. Many probiotics for dogs – like PetLabCo.® Probiotic Chews — are suitable for daily use according to package instructions and can be given to dogs as part of their lifelong wellness regimen. They are also particularly helpful during and after antibiotic treatments, during periods of stress, after dietary changes, or when your dog exhibits signs of occasional digestive discomfort. Your veterinarian can guide you based on your dog’s specific needs.
If a time of day is not specified in the directions for use, you can generally give your dog probiotics when it is most convenient for you. Some pet parents prefer giving dogs probiotics first thing in the morning when a dog’s stomach is less acidic. Others choose to give probiotics with meals to minimize the likelihood of digestive upset. You can also ask your veterinarian for a recommendation.
Probiotics are live strains of healthy bacteria that help dogs maintain normal digestive function and support overall gut and immune health. Giving dogs daily probiotic supplements may normalize bowel movements, provide support for occasional loose stools, and even help dogs dealing with seasonal allergy discomfort.
Our Probiotic Chews are formulated with prebiotics, probiotics, and postbiotics to promote dog gut health, help maintain healthy yeast levels and support seasonal allergy discomfort. In fact, a 29-day clinical trial found that using our Probiotic Chews daily significantly enhances a healthy inflammatory response in the gut.
The time it takes for a dog to experience the benefits of probiotic supplements will vary and may depend on a dog’s age, breed, genetics, health, and overall lifestyle. It is generally suggested that dogs take a supplement according to package instruction for 60-90 days to see the full benefits take effect.
In an internal feedback survey of pet parents with a Probiotic Chew subscription, 84 percent of respondents saw expected results after 3 months of daily use.*
* Results based on Probiotic Chew subscriber internal feedback survey conducted in March 2022 (n=300).
