Excellent Probiotic
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
My little almost 6 month old chi pup eats everything inside and outside and was having explosive diarrhea. Canned pumpkin helped, but having used FortiFlora Probiotic for a previous furchild, I knew that it would help my little guy. I only use half a packet because he is so tiny. Instant relief! Superb ingredients, reliable, and my boy loves it. I just sprinkle half a packet on his kibble and he eats it with so much enthusiasm. And no more liquid explosions! Yes, it’s expensive, but it’s extremely effective and my baby is worth it. Highly recommend. ... show more

⭐⭐⭐⭐⭐ Helped My Dog's Tummy Issues Within Days
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
My veterinarian recommended FortiFlora when my dog started having occasional digestive issues and loose stools. I was honestly surprised by how quickly it seemed to help. Within a few days, her stools were more consistent, and he seemed much more comfortable overall. One thing I really like is how easy it is to use. The individual packets make it simple to sprinkle over food, and my dog eats it without hesitation. In fact, she seems to enjoy the taste and licks his bowl clean every time. I've also noticed less gas and fewer stomach upsets since adding this to her routine. While it is a little more expensive than some other probiotics, the convenience and results have made it worth the cost for us. If your dog struggles with occasional digestive issues or is recovering from a stomach upset, this is definitely a product I would recommend discussing with your veterinarian. ... show more

It worked for my dog
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
Simply outstanding, my Vet recommended Parina plan probiotics for my dog who’s taking a medication that has been upsetting her stomach, and I am telling you this works. She was having diarrhea and vomiting from the medication and since taking this, everything has been so much better I will tell you that I add this to a dollop of plain nonfat Greek yogurt and mix it in and she eats it right up so she loves the taste of it. She is a 15 pound medium size Chihuahua mix and we give her one packet mix the way that I said and she loves it and it’s fix the problem. ... show more

great product!
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
I originally got this product from my ver for my dogs, but the price was astronomical. I found it on amazon and immediately set up a subscription for month delivery. I do give it to both my shepskys every day as I feel like it keeps their digestion smooth and their coats healthy. You can't beat the price. They are so easy to use, I just empty them once a day into their breakfast bowls and they eat it without any issues. ... show more

Our vet recommended and solved issue
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
Our 8 month old puppy would wake up with dry heaves in the early morning. Vet diagnosed a little bit of acid in the stomach as it had been empty all night. Vet recommended this supplement and we're now two months in. Has completely solved the problem and our Bull Terrier is doing great! I put this supplement in her bowl, add two tablespoons of water to make a gravy and drop in a little biscuit. Dog loves it - delicious and she hasn't had any other issues. Recommend. ... show more

Great for my 15-year-old dog's digestion
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
My dog is about 15, and sometimes has digestive issues because, well, she's 15 :) So I bought her some of these probiotics, and I have to say they are working pretty well so far. The powder is easy to sprinkle on her food, and it does not have a strong odor, so she eats it all up. Her digestion is definitely better and I will absolutely continue using this product to keep her as healthy as possible. I would change two things about this product, and they are both to do with packaging: The probiotic comes in individual packets, and since my dog is only 25 pounds, I usually only give her half a packet at a time. I would have preferred if it were in a container with a scoop rather than packets for ease of use. Also, these packets are very flat and can be hard to open once you tear them open, which is frustrating. Other than that, it's a nice product. ... show more

This product really works
Flavor Name: Unflavored Total product quantity: 1.06 Ounces
This is an amazing product! My dog has always had gastrointestinal issues. A few years ago My dog's vet recommended this product to me. When I started him on it, I immediately saw an improvement. He presented with less symptoms and the longer he's been on it the less episodes he has. I highly recommend This product to anyone who has a dog with a sensitive stomach or bowel issues. This product is extremely easy to use. The box comes with 30 individual packets. You just sprinkle the Powder from 1 packet on their food once a day. My dog seems to like the flavor. My mother also uses this product for her 2 dogs and they like it as well, and she has a yorkie who is a very picky eater. ... show more
