My 5 month old yorkie loves lambs heart, but i am just wondering is it good for her, i buy the lambs heart from my local butchers and I cut it into fours (with my eyes closed) and she has two of the pieces twice a day mixed with about a handful of dried burns dog food, its only when someone mentioned to me that heart has protein in so I am now worried that I am giving her too much protein

......i have had more worry and stress with my dog than I ever did than my two kids, lol........i would hate to stop giving her the heart because she loves it and she gobbles it down with the burns as well, but when I was giving her chicken with the burns the sly little thing used to pick the chicken out and leave the burns....
Has anyone any advice or suggestions.
thanks
Vicky
