If you have a dog, you need Kotbeutel, that's clear. Only where obtained good Kotbeutel? In some cities, bag dispensers are available, but they are often empty. The bag had been purchased almost always a bad quality. Here I have found Kotbeutel that meet my requirements: big enough (have a big dog), tear-resistant and they can be zuknoten well. Price Leistungsvehältnis not be topped.
