Give to all of my oups

I love this product- I even signed up for auto shipping so i can keep giving this to them. It is a prebiotics and a probiotic. I researched so may different products and decide this was the one. So glad I did. I can even give it to our pup who have severe allergies

HIGHLY recommend!!

This was recommended by my vet for my Anatolian Shepard's occasional intestinal issues. On a whim I decided to include it in my American Bully's food as she was having loose stools and skin allergies. Both dogs now have healthy stools and my bully's rashes have all but disappeared. Won't go without it.

Great product

My vet recommended this years ago for my OES And it was wonderful since she had a touchy stomach. I’m now giving it to my 6 yo Standard Poodle who experiences a similar situation, esp if we need to take her in the car. So happy Chewy stocks this!

Good supplement usually, but I was sent an unlabeled product

I received this product as a blank white bottle with nothing on it except a barcode sticker on the lid. I was given a full refund by Chewy, but I'm unnerved that it was shipped to me like this in the first place. I don't feel comfortable giving my cat a mystery powder that isn't labeled.

Review of order

It was recommended by a holistic vet who helped me get my baby off of kibble and onto home cooked meals! I will definitely be keeping this on hand for daily use to make sure my baby gets the pro and prebiotics his tummy needs to stay healthy!
