My last dog had food allergies and we fed her only zd until she stopped having symptoms. Then we tried one food at a time for a few weeks to see if it caused symptoms. If it did, we started the whole process over again until we found a food that worked. When I used it about 6-10 years ago it did not have chicken in it. It had hydrolysed protein so it would not trigger allergies.
