Review: This works almost immediately and is a must have for dogs! A lifesaver! My toy poodle got scary diarrhea from colitis. I tried giving her FortiFlora and she threw up which could’ve also been because I gave her a full packet according to instructions, but she probably should’ve had less. However, this product didn’t upset her stomach and worked right away, plus dogs love the taste. I also gave her half of the recommended dose.
Review: 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.

## Questions & Answers

**Q: is this for everyday use?**
A: I use it as-needed and it works quickly and well. My opinion is that if diarrhea and soft stools are more frequent than a once-in-a-while occurrence, the dog’s diet should be re-examined. Diet is often a telltale sign that the dog is not on an appropriate diet for his or her “constitution.” The question of whether nor not Fast Balance is safe or recommended for daily use, however, is probably a good question for the manufacturer. Hope this helps!

**Q: Is this just one 35cc tube for $18.70? My dog weighs 30 pounds, based on the dosage chart, this would be gone in one day. Is that correct?**
A: Yes, that's correct. It isn't cheap stuff, is it? But I've always found it to be an exceptional product for dogs with digestive upsets. Amazon's 18.70 for Auto-Ship is the best price I see in a quick search, unless you use Rakuten and order from a site where you get cash back. The paste also comes in a 60cc tube, more expensive, of course, but you'd have more if you need it. VetriScience also makes a daily chewable we have on auto-ship from that "C" place to keep the girls' guts in shape. Sorry to be long winded. Hope your sweet pup will be well!

**Q: I just got a tube of this in the mail.  No tip cap-missing. And when I turned it  to 5cc's-this watery stuff came out-is this normal?**
A: No, I don't think it is. Mine is like the picture with the small cap on the end. I would think if your cap is missing then the medicine is exposed and I wouldn't want to use it. The medicine inside is an dark orangy color and thick. I squirt a small amount on my finger (because I give it to our two 5 and 6lb Yorkies). I would re-order and send that one back. Once you get it, it is amazing and gets rid of belly aches etc. with in a day or so, great stuff!

**Q: Does this come with the large syringe?**
A: Actually it would come in a  syringe form. Ready to use.

### ⭐⭐⭐⭐⭐ Review
*by T***N on 9 January 2026*

It works!! Totally happy and surprised. I’ve tried everything and this did the trick finally. Kitty finally has solid poops. After rounds of dewormer and probiotics, 3 days at 2x a day. Easy to use, just put a dosage on my finger and spread across her gums. She seems ok with flavor so very excited and buying more to have on hand.
