I'd like to add my endorsement of Olweo carrots. When we got Rocket he had frequently had runny poo, and on two occasions it got body. Of course we immediately took him to the vet. $100 worth of meds and putting him on Hill's k/d prescription food seemed to take care of it... for a week. Back to the vet for more meds.
When I read about the Olewo carrots here I decided to give them a try. We haven't had any more problema with him. He has had a couple of instances of rumbly tummy (very loud, which was the warning sign that he was about to have his bowl problem) and he chose to skip a meal, but then he is back to eating without any diarrhea. After we had him on the carrots for a while we switched back to normal kibble without a problem. I believe it is the Olewo carrots that have done the trick. Nice solid poops.
Thanks for the advice!
