I have 2 dogs who do not have these issues at all with any food and one that has these issues with every food that is low fiber. I take that to be an issue with my dog, NOT the food.
I have cooked and puree pumpkin and it works great. I live in a hot climate, so I don’t melt the ice cube first, but you definitely could. I give it before I freeze it the first day I open the can.
Rice and other grains are cheap, so dog food companies use them to bulk out the calorie count on cheaper foods. They do have some fiber in them, but are primarily carbs.
