Coco has been eating Ziwi Peak with absolutely no problems (other than occasionally not having an apetite). No stool problems or anything. I have had her on venison, and venison + fish, and decided to try lamb this time around. I did mix it VERY well, and there is a higher ratio of the venison than there is the lamb. She has thrown up a couple of times since switching. Not every meal, but once in a while. She is not acting sick or lethargic, she still has normal poos, eyes are clear, nose is not running... could this mean she is allergic to lamb?
