Does your dog have problems during thunderstorms? Does he or she display behavioral issues related to separation – either from you or your family, or from other dogs in the house? Zylkene is an all natural product derived from milk proteins to help your anxious dog. Unlike sedative medications, anti-depressants, and anxiolytics like Valium, there are almost no side effects related to Zylkene administration. Many pets can really benefit from this new offering, and we have seen some really impressive results. Let us know if you have a nervous-nelly in your house, and we can try to help!
