So are dog whistles effective? In our experience, definitely. Anyone who's lived in a windy or weather-beaten place knows the value of a good loud whistle. They cut through wind, rain and even hills when your voice is simply not enough. HOUNDWORTHY dog whistles are both stylish and practical, produced in small batches by dog people who know a thing or two about recall training. Choose from sustainably sourced naturally shed Scottish stag antler or polished ox horn whistles.
