    Good product

    By Cosmo on Apr 17, 2021

    Was looking for something to help my little girl with her digestion and these work very well. I sprinkle a little on her food and it does not appear to affect the taste of her food. She’s small so I don’t give her a full one but so far so good!

    Great product!

    By Emily on Feb 19, 2021

    I have a 3 year old pittie mix who has constipation and digestive problems that impact his ability to eat. Being on this probiotic for 2 weeks has already regulated his digestion and I’ve even noticed his skin is softer too! 100% recommend

    My Bad thought I purchased chewable

    By NashsHumanMama on Nov 13, 2020

    I was looking at chewable probiotics and then I had chosen thus one. When it arrived I saw it was caplets oops. I open them and sprinkle it over wet food I had to buy. I'm sure it does the same thing, I just can't fight my dogs to get them to swallow a pill everyday. Will look for chewable.

    Best probiotics

    By Probiotics on May 5, 2020

    I’ve been using these for years because my dog has a really sensitive digestive system. Never had a problem after I started giving him these eight years ago. Very reasonably priced and difficult to find online. I was lucky to find them on this site.
