Most plastic bottles are made from polyethylene terephthalate (P.E.T.) and take about 400 years to decompose. On the positive side, they're highly recyclable! We saw this as an opportunity to educate, help our pets, and help our planet. Our leash webbing is made from recycled plastic bottles. As we shift our buying habits, we make a positive change in our world. Never underestimate the impact of small change. Rethink your walk; WALK with us.
