Great for nausea

My dog skippy dealt with a lot of nausea and digestive issues before he passed. The vet recommended this and it helped him a lot. You just have to sprinkle it on their wet food and it helps with digestion. The only problem is if your dog doesn't eat their food within an hour, this makes the food spoil a LOT faster. I feel like it has some kind of flavoring in it as well, Skippy perked up whenever I opened the packet and it would make him more excited for meal time. Obviously see a vet if your pet is having digestive issues, but this is a good price friendly supplement to add on.

This stuff WORKS!!

Our Westie came down with diarrhea and vet recommended FortiFlora and it sure does work! It took a couple days of her getting the probiotic each day but I was so happy that it worked!! The other reviews made me hopeful that I too could come back here and share how great it is! We give it to her every day sprinkled on her food and she loves it! We are going to always give this to her!!

Great Product

My dog was having diarrhea often, but since putting her on FortiFlora she has not had even one bout of it. I gave it to her every day for a month and she was cured. I had previously given her a couple of rounds of antibiotics from the vet and then she would have the same problem. I now just give it to her every 3 days and she is maintaining a healthy gut.

I believe it works

My dog developed serious gas. I tried 2 different probiotics and switched her dog food, nothing changed. My vet suggested I try this one before switching her dog food again. The gas has definitely lessened. I am hoping it resolves completely after being on it longer. It hasn't even been a month.

Amazing Product!

I'm so glad that I could buy this amazing product from Chewy instead of getting it from my Vet seeing that they charge Way More. My dog has always had stomach issues and this product has helped her maintain good doggy guy health, highly recommend it, thanks again Chewy!

Really works

One of the techs at my vet office recommended this product after my dog kept having recurring bouts of diarrhea and always had terrible gas issues. It really works. Been using about 3 weeks now and there has been no more diarrhea and absolutely no gas.

Staying solid power

We give this to our dog who has advanced digestive issues and is in poor health to help relieve GI discomfort. The powder mixes in well with his food. He eats it without any refusal and the item aids his digestive tract allowing his stool to bind well.

Absolute lifesaver!!!!

I have a 17-year-old Pomeranian who has been experiencing tummy trouble for the past few years. She deals with chronic pancreatitis, and has dealt with low appetite. Getting her to eat has been a major struggle and she's half her previous weight. After an ER vet visit; the veterinarian recommended we try FortiFlora. Worth absolutely every penny! I dilute this in bone broth or meaty baby food and feed her a packet a day. The difference is night and day! She not only eats, but eats enthusiastically!! She hasn't had bloody diarrhea again since I started giving her this daily. She's starting to come back up to a healthy weight (slowly but surely). I never would have anticipated this supplement having such a huge impact on her health. I wouldn't hesitate to recommend this to anyone on the fence, it's worth a shot. This has been a game changer for my little girl. Thank you!!

Lifesaver, literally

Earlier this year (summer 2022) my Carolina Special poisoned herself on some pokeweed. This specific plant causes horrible GI disrupt and we think has permanently damaged her large intestine. First the vet tried an antacid, antibiotics and something else but poor Nugget was still puking everything she ate and the lining of her intestines kept shedding in foamy dog diarrhea. Within a few days of starting this probiotic she was able to keep food down and within a month all signs of the GI issues were gone. This was a literal lifesaver and Nugget will be taking it daily for the rest of her life. We also have a Saint Bernard x Great Dane mix who has had life long doggie IBS basically and every single meal of his 6 years of life was a fight to get him to eat. Since Nugget had already had such a fantastic result on the fortiflora we started giving it to Chuck. He has been on it a little over four months and has an awesome appetite for the first time in his life! His chronic soft (and sometimes urgent) stools are a thing of the past! So we give this a 100/10. It isn't the cheapest probiotic on the market but it has had absolutely amazing results for us.

Best probiotic on the market

There are a lot of probiotic supplements available, but FortiFlora delivers the most consistent results of any that I've used for my dogs. Whenever I have a pup on antibiotics, I order a box of this too. I recommend it to so many people who have pups with sensitive stomachs as well because it's so effective. Highly recommend!
