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!

This product helps my Jericho with his GI health, he is notorious for consuming rabbit and deer “raisins” in our woods resulting in GI issues.

Excellent product

I had bought products from a private and expensive company. After 2 wks. I hoped to see something. Anything. No results. I used this and saw results. Keep in the fridge!! Great price for amount needed.

Works like a charm!

Our vet had prescribed this to our Golden who had the occasional diarrhea. He would have these little episodes of diarrhea that wouldn’t stop. Once we started sprinkling two scoops on his food twice a day it took about 36 hours and all was back to normal. This stuff is incredible and so good for their digestive tract. Highly recommend if your pups or kitties have occasional tummy issues.

My Yellow Lab loves it!

So my yellow lab is not a picky eater but has a horribly scared GI tract, story for another time. But I was given this probiotic by her Vet after about of colitis. I have given her probiotics ever sense, of course with stents without. She actually will not eat her morning meal without it sometimes. I've also tried the Dr.Lyon's brand. They both work, but I find this one to work the best!!
