Well welcome aboard!!!!! You are in the right place to learn about foods and work on his allergies. @cowsmom knows everything about food and ingredients etc so she can help you if you want. What brands do you feed? Is he on grain free? Chicken is hard on many bullies so that could easily be the case. There is a buzz going around about hair analysis for allergy testing and it is like 50 bucks or so, not a bad deal. I havent done it yet but am going to with my Miila who too has a hard time with everything including seasonal. A photographer huh? ugh..... I really stand no chance of winning the photo of the month contests with so many great photographers here. Will go check out your album now, your family sounds awesome.
