It’s definitely helped our Dachshund!
I got my first box from my vet after my dog had bad diarrhea and digestive issues. This product combined with a prescription food, she’s been doing amazing! Poops are back to normal and hardly has any gas. I just received my second box after my vet recommended she be on it for an additional month. The only thing I have to do is mix it with a small amount of wet food because she’s not really a fan of the powdery texture, but it works great and she doesn’t know the difference when it’s mixed in.

Essential and Effective
If you want your dog to have firm stools, you’ve got to feed him a probiotic and this one is excellent. I’ve been buying this for over a year now. U just sprinkle it on his morning food, easy peasy, and he scarves it right down..

Definitely helps my dog’s digestion
I put one packet on my 15-year-old Corgichihuahua’s food every other day and it does seem to help with his digestion. He is active and healthy for his age. These were suggested by my vet while my furry friend was on antibiotics and I thought it might be good to continue afterwards.

Works well, but a bit pricey
This probiotic really helped improve my dog’s digestion and overall gut health. My pup takes it easily, which is a plus. The only downside is it’s a little on the expensive side, but definitely effective. Would recommend!

Excellent product
This is excellent for when my dog is in antibiotics which can upset her GI tract. She loves it. I just sprinkle it on some wet food and she gobbles it right down.

Helped with my dog’s diarrhea!
I bought this supplement as recommended by my vet when my dog had an extreme bout of diarrhea. She is about 12 lbs and I gave her a single whole packet sprinkled over her food. She actually loved the flavor! After consuming it it had given her constipation for a day (possibly a side effect of having too much even though I gave the recommended dose), so I suggest if you have a smaller dog don’t give them the full recommended dosage at once and give them half the sachet to start. It really helped her though! The next day she had pooped perfectly.

Would have dinner without it !!
This product is very recommended by our vet. It works magic with trouble tummies. We have been using this for years and have no had concerns. We will sprinkle it on their food add a little water and warm it up and the smell is very appealing to them. I always have it at the house. Great ingredients, smooth coat, great tummies, and they it right up !!

My dogs had upset tummy’s and I could not buy this product locally. It worked wonders to get their digestive system back to normal in just 4 days. I am not continuing to add a lower does to their food until I can know that they won’t get diarrhoea again.
