⭐⭐⭐⭐⭐"We are loving our new High Tails long line. The color purple is lovely, the weight is perfect, and easy on the hands. We use just about everyday when we go for walks in our local park. I also like that the leashes are made in the U.S. and that you are a woman run company. They came highly recommended in a FB training group that I’m in." - Donna K.
