I use flexi-leads to walk the boys, and I use a 4 prong cane to walk myself. I have tried a coupler and they tangled and tripped each other. Individual leashes are too short and they tangled all around me.Flexi-leashes were the answer! Baron walks faster and his leash goes over Sammy's head. They both are on my left side.My cane is in my right hand!! My hubby thinks I should join the circus. It works for me...
