I have been using these for the last 7 years for my Great Dane. They are in a league of their own and cannot be compared to any other product of its kind. The bags are the perfect size for any pick up and the extra lining on the bag makes a huge difference. I am brand loyal and will continue to use this great product. I recommend them to everyone I know that owns a dog. Like I said they are great for my Dane and can handle the test she puts them through.
