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 Chew +, 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 isn’t specified in the directions for use, you can generally give your dog probiotics whenever it’s most convenient for you. Some pet parents prefer giving probiotics first thing in the morning when a dog’s stomach is less acidic. Others choose to give them with meals to reduce the chance 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 Chew + is 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.
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.
Our probiotic supplements are pork-flavoured, 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-flavoured 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.
