I cannot give this product enough Kudos. With two dogs over 130lbs, removing waste is a constant challenge particularly when the waste is not solid (a problem I have solved and will outline in a different review). These Mutt MItts do not tear or split and are as sanitary as anything I previously encountered. Because of their size, I take the dogs for long walks at 4:00am. Picking up waste used to be a nightmare but this was solved by these bags. My only negative is I wish I had designed and marketed these myself!
