April is just five months old. Together we perform therapy at the foundation for the blind children in Phoenix, Arizona. Working with handicapped children, I find it helps to have my hands free of a leash. With the E-collar both of my hands are free to assist the children. We started April when she was just four months-old and already she is at a level comparable to my older dogs after a year of conventional leash training. We both enjoy the freedom of off-leash control.
