We asked over 5,600 owners what the pulling was doing to them. One in four said it was hurting them - shoulders, arms, backs, wrists. More than 270 had been pulled over or dragged.
Every lunge used to travel straight down the lead into your shoulder. On the ParoPet it turns him instead - so when he spots the cat, the squirrel, the other dog, the force goes into the turn, not your arm.
If the only person who can walk him is the strongest person in the house, this is what changes that.
