My dogs have sensitive tummies. Now that they're older I thought this would go well after the Sensitive Stomach & Skin kibble. They had no problens with other Perfect Digestion kibble in the past but I believe the addition of the pecan shells are the offending issue. My little gal became increasingly uncomfortable. At first it seemed fine but halfway through the bag I noticed her being very fidgety & unsettled at night. I gave some to my other dog & he loved it but when I started adding it to his food, he was eating grass & throwing up outside.. The lightbulb went on when I saw someone on the Hills site complaining about the pecan shells being added to the i/d kibble & her dog was also throwing up. I still have about 1/3 of the bag left but it's at the point now that I can only add 1 tbsp to their food twice a week. I just used my $30 egift card to buy 2 small bags of other Hills senior kibble, senior vitality & 7+ chicken flavor. Hopefully 1 of those will work out for us. We never had a problem with any Hills kibble but we have to be super careful with canned food. This was disappointing.

Not sure if I will order this again. Dogs are having trouble to adjusting to it. I'm doing the mix and match thing but both dogs have had the runs. So thinking something in it isn't setting to well with them. Might have to give to shelter and order them the regular stuff again.

I thought this would be good to try to firm up my dogs stool a little - adding just a tablespoon a day to start a 10 day transition. At day 3 she was so constipated she had just something like melted butter and blood. After an emergency vet visit, she had pancreatitis! Never have had that happen to any of my dogs in all my life. Now she’s on an antibiotic and prescription food to try to undo what 3 days of this food caused. Horrible!!!

We occasionally get a slightly dented can here and there, which is within the normal range. But, our last order had 6 severely damaged cans with huge dents and a few with minor dents. Our dog didn't feel well for a few days after eating the severely dented cans. we stopped giving him those after the 2nd bad can.

Thought she might like the Chicken in it.

She wasn't crazy about it and even though we gave her plenty of time to adjust to it, her stools were too soft and won't firm up. She wasn't a fan.
