Only treats my Yorkie/Cairn mix will, eat and my 30 pound mixed breed will eat almost anything, EXCEPT the Spirals come from Vietnam. I had a bag from Vietnam and one made in China. I gave him spiral from Vietnam and he would take it, taste it, then dropped it. I have him spiral made in China, he tasted it then sat down and ate it happily. So, make certain you know where the Dream Bone Spirals are manufactured before purchasing.See full review
