At home here, Dh and/or I walk Cooper down the street (we live at the side of the hill) where there are a lot of distractions, cars, trucks, motorcycles, etc. He only turned 5 months so he can still be easily distracted. Practicing "no-leash heels" we do it inside our house or in front of the garage but at our hangar down the airport, we usually take a walk and look at other hangars and other airplanes. It also helps him to socialized with other people at the airport...
