My 3 dogs love it, and it’s absolutely necessary for them to stay healthy without stomach issues.

My male tuxedo is 6 years old and we've noticed he's had some sensitivities over the last year. Low energy, occasional upset stomach and lately he's been dealing with diarrhea and coughing (almost like trying to cough up a hairball). I read it may all be GI irritability which broke my heart. I imagine it's not only uncomfortable at litter box time but must make them feel under the weather trying to digest meals. I gave him this last night mixed with his favorite wet food and he did not seem to mind it one bit - he seemed to like it even more! I forgot all about it, assuming it would take days or a week.. but 10 minutes later I came out of my bedroom to him having the zoomies ALL over the house! I couldn't believe it! I haven't seem him with that kind of energy in YEARS. I figured he maybe got a spurt of energy after not feeling so upset after a meal but this morning the exact same thing happened! He not only was eager and energetic before breakfast, but was bolting all over the place 10 minutes after breakfast! I did not notice any diarrhea sounds/smells this morning which made me so happy for him. I've not senm him this perky and happy in a VERY long time. HIGHLY recommend!!

My dog tends to get upset stomach often, and when I discovered this product, it solved the problem. No more tummy aches or upsets for my pooch. I'm very pleased with how effective this is for dealing with dog stomach issues. It's so good I now have it auto-delivered every 6 months to make sure I always have a tube.

My cat has tried multiple probiotics but he responds best to this formula and its fast acting. For flare ups this is the best OTC supplement for him and its completely worth the price, I buy this in bulk to ensure its always at hand and he takes a couple weeks of treatment sometimes. Add B12 supplement for comprehensive solution. Also this is easy to measure dose and adminiser. My cat doesnt mind the taste so will eat it begrudginly when put in his mouth.

The paste works, but you can’t use this syringe to give it to your pet.It doesn’t work as you think.You have to almost use 2 hands to push the end to get the stuff out, because it needs significant force to come out.I didn’t know till it was time to give it to my cat. I was struggling hard and my cat was freaking out. The stuff was all over my cats face and I just had to stuff her mouth with the paste with my finger. Both me and my cat was traumatized after. I let my cat run away to another part of the house and I haven’t seen her in hours.

Simply put it works. Tummy aches. Tummy issues. I put the correct amount in a small bowl and dip my finger in it and smear some quickly onto the roof of my dogs mouth. I do this until its gone from the bowl. I use the “vet method” to give him this stuff. Look it up for some help. It worked. This paste hasnt let me down when I needed it. It saved me a two trips to the vet. My dog has severe acid reflux and this is a huge help for us. I ordered another one just to have on hand. I highly recommend.its not supposed to taste good. Its medicine. So i am not going to pick apart the products’ appearance, taste or smell. Every pet owner should have this in my opinion.Update: this stuff is still absolutely wonderful. I have had to use it several times this past month. My dog’s stomach acid acts up if we dont get up by 4 am every single morning for a snack. When this happens he wont even go near any type of food or treats. This paste works in sometimes ten mins. Sometimes, 20-30. But it has yet to let me down. I still open his mouth putting my finger only on his front bottom teeth and stick the product on the roof of his mouth very quickly. Side teeth they bite down. But if all my fingers stay in the front, he wont bite down. Hes super gentle anyway. I do like to spray his mouth with a little water to help the product work its way down faster but not enough to dilute it. I also dont put too much on my finger at once because then he can spit it out. Just a little at a time while speaking words of encouragement so hes not scared as prying a dogs mouth open can be kinda traumatic. This lets him know everything is ok. I just love this stuff and I wanted to help. SO many reviews on dog products and supplements have helped me out throughout the years and I have depended on them. I wanted to give back.

This stuff is a real dog saver!!! I could not recommend this product more. My pet has a sensitive tummy before she would have to wait it out for a day or so. With Fast Balance in 30 min she is back to normal. All natural products. I thank you and my pup thanks you.

Zeus (my dog) has Crohn's disease. In Februray 2016 he became a medicinal cannabis patient and has been comfortable and controlled almost 100% eve since. The only time I noticed tummy pain/grumbling after beginning the cannabis was when I wasn't home with him. Giving him one of these probiotic chews before going out completely stops this painful tummy for him! Very happy to have this product to supplement while I'm away!
