Questions & Answers

66 Customer Questions

My dog is currently on dog kibble from Hills Science I/D. Does he need to take the same brand of digestive supplement so it doesn’t interact with his current brand of food? Is this considered a new brand of food I’m introducing and have to ease it into his diet over a week?

Anyone else notice the packets have different amounts in them? Sometimes a lot sometimes a little.

Does this product have to be given all at once/at one meal, or can a packet be spread out over the number of meals the dog has per day?
Answer by ChewyApr 10, 2023
Feed 1 packet to your dog daily under the supervision or direction of your veterinarian.

Has anyone used this to help relieve constipation?
Answer by ChewyMar 13, 2018
The supplement is formulated promote intestinal health and balance as well as a healthy immune system which may help with constipation.

It actually works!!!

Long story short,.my 3 year old silver lab had a spinal stroke and can no longer eliminate like a normal dog. Having a bowel movement for him is walking and pooping..lately his pooping have been tough for him. His poops have been small, not consistent, if anything every other day he would have a bowel movement..but for the size he is and how much he eats..definitley he was not getting enough out. Sometimes he would pass gas when he would try to have one..and nothing would come out. I've tried everything out there except for this. I was hesitant on buying it just simply the price..i didn't know much about it other than it was 30 bucks..and Odin already being on a prescription diet and acupuncture appointments.. However I bought it, and already day 3 and he's pooping twice a day. Also they are normal color and form. I will continue to purchase it. Definitely worth the money. Thank you so much for the product.

What a difference this has made for my dog that has had soft poor quality poos his entire 4 years of life. The vet recommended this when my pup was experiencing diarrhea. Not uncommon for him. This particular time there was a reason but most times there is not. His poos are much less in volume, and I am able to pick them up with non-left in the grass. Another great thing is he LOVES the taste, just sprinkled on his kibble and he eats wonderfully, no looking at it and turning away. I am extremely satisfied with this product.

Works great!

Scruffy got put on this when he was prescribed antibiotics, and it worked great, but I was having trouble getting him to eat regularly. My vet said sometimes dogs just like to have this sprinkled on their food, so I continued to give it to him after the antibiotics were done, and it certainly does get him to eat at least a little bit even if he's having a rough day for other reasons. Also it makes antibiotics much easier to deal with, if you know what I mean :)

Really helps regulate dog’s poop

Are dog has had a lot of digestive issues and other issues causing her to change foods often. And this has really helped her poop not get too runny during that time. We will probably keep her on it or at least half a packet a day until she’s out of puppyhood to help regulate everything as she’s trying different treats and adjusting to the transitions of food.

Upset tummy gone!

Ever since our Havanese started using the Purina Pro Plan Veterinary Diets FortiFlora, all his upset tummy problems have literally disappeared! Jackson was prone to stomache upsets for a very long time and when his vet suggested we try the supplement (we simply add it go his daily feeding by mixing it in), upset tummy gone! Barkin' good!

Purina Pro Plan for a digestive supplement for dogs.

I own a poode/mix rescue cutie who is now 8 years old. Her nose is always on the grounp and any hole is a gift to her. Therefore, she can get into real trouble because we don't know what is that hole. She has never had a sickness from her hunting, and I depend on the probiotic supplements. They are not inexpensive, but they are worth the avoidance of having her get sick.

I Don't know yet

My "Kids" have only been on this for a month now. I have no idea if it works or not. They do not have any changes in their behavior, so I suppose I would have to give it a while to see IF it works...... For the exception of ever since my kids were on this, one of them has had diarrhea & still has it without ANY changes in their diet.

Great product

Not only am I happy with the product. I can’t say enough about Chewy and how well they have treated me and how amazing their customer service is. Everyone is always very polite and helpful. They are simply amazing I hope the folks that have helped me the two times I needed it get commended on their excellent service they provided for me.

Chevy says NO!

My Rottweiler Chevy has very bad gas and the vet recommended this Purina FortiFlora and so I ordered a box and put it on his food per the directions and he smells is and won’t eat , or eat very little and still has the clear the room gas. So for us it’s a No go!

Wouldn’t feed my dog without this!

My dog has had to be on multiple antibiotics and this has helped his gut health stay in tact! Plus, now he turns his nose up to food if it isn’t in it! He loves it! I’d recommend anyone with a canine or feline (we give the feline version to our cats) use this product daily!
