Review on Merrick Grain Free Real Chicken and Sweet Potato Recipe: Premium Dry Dog Food by Abunsefer Chongbang

Is it possible to get a bad batch? I've ordered this several times with no problems but the last pack I had made my dog flare up and he stopped eating it after three or four days and I didn't understand why. Then I noticed a breakthrough. I have another meal we ate before (blue buffalo in the desert) and he ate it. I've been feeding him blue buffalo for a week now and his hives are getting better. I ended up throwing away the rest of the Merrick meal (worth about £20). Before that we had no problems with Merrick.
