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!!

very good product

My vet started me on this for my 13 year old Shiba. It seems to alleviate some digestive problems that have plagued her all her life. She eats well and plays like a 2 yr old (also acts like a 2 yr old).

So far so good

I have always added a probiotic to my dogs’ evening meals but also include alternating kefir and goat milk in their breakfast. Chewy carries this one that is holistic vet recommended at a good price. So far so good.
