Contigo Dogs poop bag holders are made from 100% hemp. We have partnered with Pushaoo to offer this exclusive sustainable product here at Contigo Dogs. Hemp has rapid growth (it takes 3-4 months to reach maturity) making it one of the fastest CO2-to-biomass conversion tools available. Hemp is naturally pest resistant, at least twice as strong as cotton, and production requires less than a third of the water needed for cotton!
