Food storage

I love it and it holds a complete 16 lb bag with no problem. I don't pour the dog food out of the bag into the Container because I was instructed by a veterinarian

I love it and it holds a complete 16 lb bag with no problem. I don't pour the dog food out of the bag into the Container because I was instructed by a veterinarian not to do that. My only complaint is that there are no instructions on how to assemble the wheels and they are very hard to get on. So therefore the wheels are not on mine as of right now

Kiwi's vet strongly recommended that she start a probiotic when she was a puppy as she would get frequent UTIs on top of having a very sensitive tummy. After consistent use for multiple years now, I can truly say that I've seen a difference and it has kept UTIs away! I have also use it for my other dog, Marilyn, when she has an upset tummy and it seems to help her quite a bit too. For less than $1 per packet, it's very affordable!

I tried perfect poop. I tried multiple different probiotics and pre biotics. I tried enzymes. I was on Reddit. I was very sad. My dog had constant diarrhea and she’s not young. I tried changing her diet to bland food. Finally, I have her on sensitive stomach hills and this little packet. It was like magic. She has normal bowel movements. It’s been a week and it’s been amazing. She feels better and ecstatic. It was a life changer.

Lifesaver

If you have doodles, then you most likely understand the gut issues. I swear diarrhea was my dogs baseline it didn’t matter what i fed her, how often or how little, she had runny poop EVERY SINGLE DAY. I tried so many supplements and yea it would help a little but her poops were still always so soft! I started using this, and it has been absolutely life saving. I even ran out of it for like a few weeks and she immediately reverted back to soft runny poops. It has been an essential in our house. 10/10

My pup was having digestive problems which led to diarrhea. Royal Canine was not inexpensive but it was the brand she is growing up on. A neighbor gave me a few packets of that Purina Pro Plan digestive supplement and it worked no more diarrhea. I give my pup a small amount on a regular basis. 1 packet is good for 3 days,just sprinkle a little once a day on the food.

Noticeable Improvement in Digestion and Gas

This probiotic has been an absolute lifesaver. My dog developed allergies and gas, especially at night so bad that I had to sleep with a fan blowing directly at my head even in freezing temperatures just to survive the smell. I make my own dog food and it works great for my fur girlies so didn’t really want to change it. After starting this supplement, the difference was unbelievable. Within days, her digestion improved. The scratching stopped and the gas completely subsided. I can finally sleep comfortably again with no fan, no fumes, no regrets. This stuff is worth every penny. Highly recommend for dogs with sensitive stomachs, and owners who value their oxygen.

The price is crazy. Performance is mediocre.

Over the years we have used this multiple times with our canines. Usually one that is extremely sick and the vet is writing multiple prescriptions for, so I agree

Over the years we have used this multiple times with our canines. Usually one that is extremely sick and the vet is writing multiple prescriptions for, so I agree to add it. Each time I regret it and the canine ends up using this Pro BIOx Supplement product that works well with canines, felines and ruminants. Not my choice for canines.

Great product when pet is on an antibiotic to keep GI tract in check

I have good success using a packet of this mixed in with a few heaping tablespoons of pumpkin when my dog is on a course of antibiotics. It helps keeps his GI tract

I have good success using a packet of this mixed in with a few heaping tablespoons of pumpkin when my dog is on a course of antibiotics. It helps keeps his GI tract in check and avoid the unpleasant side effects of antibiotics like diarrhea, indigestion, belching etc. I always keep these and pumpkin on hand. It replaces the normal flora in the GI tract that antibiotics kill.

We adopted a 3 year old dog 2 months ago who came from a very neglectful background. Not surprisingly he had very bad digestive issues and FortiFlora was a life saver. In a short time he was significantly improved. My vet advised that once he was healthy he didn't need to stay on it, but I keep it at the ready in case any future digestive issues arise. This is a great product.
