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.®’s 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 can also be 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 help maintain normal bowel movements, provide support for occasional loose stools, and even help dogs dealing with seasonal discomfort.
Our Probiotic Chews are formulated with prebiotics, probiotics, and postbiotics to promote dog gut health, help maintain healthy yeast levels and support seasonal discomfort.
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, 89% of respondents saw expected results after 3 months of daily use.2
If you accidentally give your dog too many soft 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.
