Nice!! thanks for the info(s). Maybe it was only me( or my dog) who experienced accident about the chicken wings. Anyway, the thread is not about the chicken wings. LOL!
From the list; maybe I can take out the chicken bones and mouldy foods.
Maybe the what he/she means about chicken bones were the wing part of the chicken, this portion is too pointy and sharp bones that can damage the intestines of your dogs.
