Questions & Answers

31 Customer Questions

I understand dog's guts need different bacteria than human guts. Are the bacteria in this product specific for dogs?

how do you split the capsule for the feline dosage. are these like caplets?

Answer by Chewy • Mar 09, 2019
This supplement comes in sprinkle capsules that allow you to split the capsule in half with ease.

does this Vetri probiotic contain a prebiotic? I believe I read someplace that it did, but since I've been researching many of these products I've lost track of which do and which don't. Thanks

Answer by Chewy • Jul 18, 2019
This supplement contains both prebiotics and probiotics.

Does this require refrigeration?

Answer by Chewy • May 14, 2018
It's recommended to store these capsules in a cool, dry place at a temperature of 70 degrees Fahrenheit or below. Refrigeration after opening is suggested.

Our schnauzers have sensitive stomachs and are prone to pancreatitis if we are not intentional with their diets. We put this on their food once a day and it has been a game changer for them. Very few tummy issues since we started using this.

I have used this for years and know the health of my fur babies is strong using this product. Vetri Science recently changed the bottle from white to black and offer this as a chew or capsule (my preference) and it caused a bit of confusion in my recent order. Chewy was so awesome in correcting the order! I truly recommend the product and the outstanding customer service.

Impressive contents

Instead of forcing my dog to swallow it whole, I sprinkle an opened capsule on his food. As he gets older, he is benefitting from a better probiotic.

I bought this for my cats although I could give it to my dogs as well. I bought this in treat form for awhile. It stopped my cats from spitting up and my other cat had some dark saliva that has since cleared up.
