One of my girls has all fowl and tapioca allergies so I am creating charts with protein and ingredients for the potential foods she can eat. From the information I have gathered so far, I can point you in the direction of a few brands that have varieties that meet the lower protein and no potato criteria — California Natural, Tuscan Natural, Spring Natural, and Natural Balance LID. If there is not an oat allergy, you might look at Pinnacle Trout & Sweet Potatoes or Wellness Simple Lamb & Oats. These foods are lower protein than you are currently feeding (I saw in another post that you are feeding Purina Beyond and it has a dry matter content of 31% protein).
