I'm going to put Roxy back on Iams for 6 weeks or so, then I will try her on California Naturals. Not sure whether to try the Lamb or the Chicken. If that doesn't work I will consider doing a home-cooked recipe. Due to Roxy's size, I'm not too keen on preparing such large volumes of homemade food.
Marty, where did you get the histamine blood test for $75? This is obviously different than the $800 allergy testing. It would be nice to know for sure
that it is an allergy. If this is something else like auto-immune or yeast it would be best to not waste time messing around with food!
I'm not ready to spend $800 on the full allergy testing.
