The Chicken Jerky treats made my poor girl very sick. I tried giving them to her a couple times over the week to see if it was something else going on with her and each time she was vomiting within 30 minutes of eating them. I do not think it is anything with the treat, i think she is developing a chicken sensitivity, like many German Shepherds do, as she is getting older in her puppyhood. Will be seeing how my brother's dogs react!
