Corn? for perfect digestion?

I wanted this to work for our small senior dogs in my hope they could all finally be on the same diet. MOST of the ingredients seem to be well-chosen by Hills. Unfortunately one dog has significant digestion issues, diarrhea and tummy upset when he eats food with corn. And another seems to get upset stomach (eating grass and restless) with so much corn in the ingredients. The search continues for a food they all do well on ...

Made my dog worse

Unfortunately, my dog have tried this food for a awhile now and it hasn't helped at all. He not only has diarrhea frequently but he now has mucus.

Will not eat

This is the third Science Diet formula for digestive issues my 8 year old dog won't touch. I am staying away from this brand for kibbles in the future. She likes the canned food, but not always. We are going back to Instinct and Native Pet probiotics. Chewy is awesome and delivers the next day, but I still had to run to the store and get a different brand so she can fill her tummy.

Works for one of my dogs

One of my dogs loves this food, and I think he appreciates the smallness of the "bites." He prefers this non-prescription food to the Hill's Prescription Gastrointestinal Biome product. His poops are pretty well formed these days for the most part (although he is prone to diarrhea, and I would have preferred to keep him on the Prescription Biome diet). My other, super-picky dog will sometimes eat this Perfect Digestion food and sometimes won't. I wish this food was offered in a smaller-weight bag. I know it would be more expensive in the long run, but the smaller bags are more convenient to store in a small pantry.

My Morkie devours it!

Purchased for my 13 year old Morkie. She acts like the food is going to runaway if she doesn't eat it fast enough. Very small pieces for easy consumption and doesn't have an overpowering smell like some more basic brands can.

My picky Chihuahua refused it

So sad my senior Chi refused to touch it after a couple bites especially when the price now is quite high to waste. I was so confident purchasing it with the amazing reviews and past experiences with this brand's other products. Unfortunately it did not win her heart. She prefers the adult version vs senior one.

He'll eat it!

We had been giving our 14 year old cockapoo a prescription kibble for his digestive issues. Problem was, he never really liked it and recently simply refused to eat it at all. So based on the great reviews, we tried this -- he not only likes it, he no longer gets runny stools. And bonus, no vet prescription needed. Wish it were less expensive, but otherwise perfect.

Perfect Digestion

I've tried many dogfoods looking to help my small dog's digestion. This dogfood seems to work the best. The only time he has a problem is when I give him too many treats.

my dogs love it

I have been having a problem finding a food that all 3 of my dogs will eat. Plus one had chronic runny stool. All 3 like it and it has firmed up any problems. My only negative is that it doesn't come in any larger bag than 12lb. One bag a month isn't enough and 2 is a little too much for the month so I have to adjust every month on the auto-ship or order in between.

Chewy is the best

Perfect every time I buy from Chewy. There is nothing much to add, because they just beat everyone in this field.
