Before you get angry, yes this is ANOTHER food questions thread LOL. As you know Guinness has had some problems with different allergies and trying many different foods. Well I thought I had found the answer by going back to FROMM adult gold as Guinness did great on FROMM gold puppy, but after a month or so he has got an infection then a secondary yeast infection in between his toes and in his ear, which the doc thinks could be triggered by the food as 15-30 minutes after he eats he turns brought red and starts itchin and then the moisture contributes to the yeast infection. Anyways doc wants to try meds and new food (which she provided samples of) to try and see if that will work. She gave us Hills z/d and purina hyper allergenic which I know are 1 star foods. she mentioned something about the protein being hydrolized (or something like that) so the body can digest it easier without the allergies kicking in. Anyways what do you guys reccommend? I know try a 6 star food. I have tried him on every FROMM 4 star and nothing has worked. If all of this doesn't work she said we can do an allergy test but she reccommended this line of attack first. Thanks in advance guys....and girls
