Oh, and we found a permethrin that is safe to use on dogs. It was on clearance at TSC. Bought that for our dogYou can coat them yourself. Permethrin is sold almost anywhere, in the camping or bug removal sections. Walmart, TSC, Rural King... I coat any clothes we take hiking or camping, or to our land in WV. Just spray them outside and let dry. Spray shoes too. It lasts six weeks or through six washings. Stuff really works
