There are hundreds of foods to try out. Maybe your dog is not used to high protein grain free. What were you feeding before and how long? There are foods “in the middle” if you want to try that. I feed a range of 4 to 5 star foods and haven’t had any issues with more poop or larger poop. And actually my fosters have the largest and more frequent poops after being vetted and then I get them. I also give the dogs some probiotics a couple times a week. The best poops are on raw food with bones – small, formed, no smell like the size of little bird eggs. I have small dogs though. But what I’m saying is, try something else. My fosters do good on Nutrisource Heartland Select and grain free Lamb. I would call those “in the middle”.
