I have had Boxers for years and I know only too well those sensitive guts. Right now I have a 9 1/2 y/o and I feed Canine Caviar Limited Ingredient Free Sprit and Nature’s Logic Canine Chicken Meal Feast. I look for dry foods without peas,legumes or beans of any kind. I find that with the newer formulations of even Champion Pet foods (Acana and Orijen) these are being added and are in the first 3-5 ingredients and so many dogs are just incapable of digesting and utilizing legumes. I fed Acana for many years but I do not anymore. I love the company and their transparency and their mission statement.
May I ask how you feed,i.e.: twice a day or are they given food to free feed throughout the day? I’ve had a lot of Boxers which also include over 60 rescues and Boxers live to eat….unless they are ill. They do best with two feedings a day 10-12 hours apart. My hunch is that your guys just may have residual upset stomachs and hence why they are spitting food out
