This product is amazing and has worked wonders for my dachshund and extended the quality of his life
My 2-year-old dachshund had constant watery diarrhea I took him to the vet they told me there was blood in his stools I thought it was because they gave him a antibiotic and I thought the antibiotic also not only killed the bad bacterial infection he had but it also killed the good bacteria so we thought it was a simple bacterial infection come to find out my two-year-old dachshund his name is Sammy he ended up having lymphoma at such a young age he has a very rare type called Mott cell lymphoma only two cases in Japan there are no cases in the United States I was trying to find the silver lining and all of this so they're going to use my Sammy boy as a case study to help other dogs in the future but it seems like he is in a remission right now he has put on almost 8 lb he's healthy all he takes is prednisone and as needed a shot called Elspar, I was told June 2nd of 2025 I might have a week to 10 days with him now we are in September and he is healthier than ever and I give him this every day with his food it has completely stopped the diarrhea his skin and coat is beautiful he stopped itching as much and he has firm stools I'm not saying this product is going to extend his life with the lymphoma but it definitely is helping and it's one less thing we both have to worry about he's much happier and healthier and that's the best I can ask for so I get more time with my boy and healthy time with him quality time with him thank you for making such an amazing product for various reasons for us pet parents of our fur babies that we love so much 🐾🧡

We needed a top-shelf probiotic for a serious situation. This did the trick.
Our elderly dog needed a shot of systemic antibiotics, which knocked her gut flora out of whack. Our flooring was not pleased. Additionally, the shot knocked the whole dog on her backside in general. Not good. She was in very bad shape and we thought we were going to lose her. One dose of this and the diarrhea cleared up. She also rebounded dramatically, which may or may not have been a result of the probiotic. Very, very pricey but it sure seemed to do the trick when some Serious Probiotic Action was required.

Amazing stuff !
Our dog was diagnosed with ibd and could not find a probiotic that he could tolerate. I finally found a holistic vet that supported FMT treatment and this probiotic was part of the protocol…. I bought this and the fmt kit and capsules from the company and didn’t even think to search on Amazon. When my reorder was going to take over a week i searched and found it here ! Next day delivery and same price ! I now have 2 containers but it’s fine since I know I’ll be using it eventually…. This stuff has helped our dog , it’s not cheap but has helped his stool quality so much !

adequate product
good product per vet's recommendation but pricey and with a tiny scoop that has to be fished out fron container. I have no way to evaluate effectiveness of digestion or skin irritation but is well tolerated by my dog

A game changer
I have used animal biome after a recommendation for my veterinarian to do my felines gut biome, testing, and animal biome has been wonderful. Reason being is veterinarians are not equipped, nor do they have the knowledge level of diagnosing gastrointestinal issues when it comes to disruptions of the gut biome. A lot of these supplements people will immediately degrade if they don’t have any effect— I get that. But when you’re dealing with the biome of an animal’s gut, something that is up until now has not been very much explored (no one knows what the base line is really supposed to be in your animal because every animal is different) but we do have what a typical base line should look like for the first time my little girls gut is balanced, and she has no more inflammation. This supplement is the number one reason along with the other number one reason— the removal of CHICKEN from her diet. Chicken is the highest allergy known among cats typically because it’s just used in everything. By replacing their diet with orijen’s tundra and adding this supplement, it has provided a causative cure in her gut. I will likely keep them on this for the rest of their life. It’s only a half of a tiny scoop and it mixes very well in their food. I appreciate the work and efforts of animal biome that they put into their supplements and research for a very uncharted territory with veterinarian offices

Old label but current formula?
Sadly the labeling isn’t the current one that I obtained from our Vet so it’s confusing as the expiration date specifies 10/2027 but label is old version. This is an costly product so it would’ve been nice to have them state it’s just an older label for the consumer
