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).

PetLabCo.'s dog probiotics are formulated to be suitable for dogs of all sizes 12 weeks+ and most dietary needs. However, if your dog has specific health concerns or allergies, it's always best to consult with your veterinarian before introducing any new supplements to their diet.

If you accidentally give your dog too many chews, contact your veterinarian. If you’re unsure how many soft chews to give your dog, please see the Directions for Use at the top of the page.

Our probiotic supplements are pork-flavored, making them a delicious reward that appeals to a wide range of canine tastes and preferences.

Our probiotics for dogs come in a convenient, no-mess soft chew. In comparison to powders, these yummy, pork-flavored chews can be given directly, eliminating the need for mixing or measuring. Dogs eagerly look forward to the taste.

These probiotic soft chews are suitable for dogs and puppies of all breeds and sizes, 12 weeks and older.

We use high-quality ingredients in our soft chews to ensure your pup gets the best. Please consult with your vet first if you have any concerns.

PetLabCo.’s Probiotic Chews contain a proprietary blend of prebiotics and probiotics. The active ingredients include:

  • Bacillus coagulans
  • B. clausii
  • B. subtilis
  • Fructooligosaccharides (FOS)
  • Galactooligosaccharides (GOS)
  • A synergistic postbiotic blend of yeast (Saccharomyces cerevisiae, Cyberlindnera jadinii)

The PetLabCo. Probiotic Soft Chews are formulated to benefit dogs and should not be given to cats. If you are looking for something to support your feline’s gut health, our newly launched Cat Probiotic is a great option!

Our Probiotic Chews have a shelf-life of 12 months.
