This is the food I have found works best for all 3 of my dogs, I can’t find it anywhere. When will it be back in stock?

How does this compare to the Purina One Sensitive System dry food?

Affordable alternative for picky eaters

My border collies have been on blue buffalo for years and it seemed to help some sensitive digestive issues for my older female. The price, however, have been going up like everything else. I tried this brand based on price, quality and reviews. My dogs love it and it has solved my female's loose stool problem(so far) and she has less gas. It has been almost 2 weeks and they are still excited about meal time.

great substitute for expensive brands

I was previously purchasing a more expensive brand which was priced 10 pounds for $50 but when I adopted my second dog, i needed to find more bang for my money and asked the adopter who has 30 dogs and she suggested this brand. I started using and both my dogs love this brand of food. highly recommend in these times of prices going up but we love our dogs and want the best.

Gas production off the charts!

I have 3 dogs, one has a sensitive stomach, loose stools and is older. The other two are hearty eaters without issues. This food gave all of them gas. Like where is my gas mask, I gotta escape this room gas. My hubby would come in and say "OH MY GOD!!" and leave... that is how bad. I transitioned gradually, but I have to give it up. This is the worst. The dogs love to eat it though.

Yummy Food and Probiotics

Our fur babies enjoy Purina One digestive health when we don't want to spend the extra money on Pro Plan. They love the meaty bits in the food, but I wish the ingredients were just a bit cleaner. I also wish they had a bigger bag option, but it's not a huge deal. We paid a great price because we had a promotional coupon. We will continue to purchase Purina One in the future.

used to be great but makes my dog sick now

Not sure if there was a recent change in ingredients but my dog has been on this for years with no problem. I got a new bag recently and my poor pup has been having problems ever since. Vet had to give him prescription food and some antibiotics to get right again

Great for my Pitbulls

I switch to this food couple years ago when I took in my brother’s dog both my dogs are Pitbulls and they tend to have dry skin and get allergies and for whatever reason their skin has been great their ears everything like it’s whatever’s in this food works for my dogs. I’m not saying it’s a cure all or works for everyone’s dogs, but works for mine and they love it. My male would never eat any kind of food that was chicken flavored and since the first day he’s had this he loves it and so does my girl their weight is good. Their skin is good I’m happy because they’re happy.

Always in Stock

I am so thankful that Chewy always has everything in stock. Sometimes I get lazy and just try to grab a bag of dog food when I'm at the grocery store. But often times they don't have what my dog likes. Ryker is a picky eater with a sensitive stomach. He likes the Purina ONE Digestive health, and there are no ugly messes on the floor like when his stomach rejects the other brands.

fixed my tummy troubles

my miniature daschund was having loose stools and some tummy bloating. she has always loved Purina Beneful but the product seems to have changed consistency and she has aged also. we tried Purina ONE Digestive Health and her tummy issues went away and her stools and nice and firm. she runs to get her food, she just loves the taste and consistency of Purina ONE Digestive Health dog food.
