I think the maize content has caused issues.
Our Lab x loves these biscuits, but since starting him on them 2 months ago he has had chronic anal gland issues, itchy skin, and ear problems, along with very soft stools. I have come to the conclusion that, as all their other food is grain free and has long been a part of their diets, it must be the maize content causing the problems. I am switching back to Applaws grain-free, but it's a shame as my dogs love these. Only one of my dogs has been affected like this.
