Review on Earth Rated Extra Thick and Strong Dog Poop Bags - 900 Leak-proof Unscented Bags, 60 Rolls with 15 Bags Per Roll, 9x13 Inches, Includes 2 Leash Dispensers by Jocelyn Hernandez

These bags are great. They won't tear and are thick enough to block odors if you need to carry your bag while walking. The bulk option is a cheaper price but I have to throw away the dispensers as I found it much more efficient to keep a roll in my bag. In response to a comment stating that he realized he should use all the bags in 2 years time as they deteriorate over that time - they don't. If you keep them in a cupboard, they won't spoil at all. If you don't believe me, take a look at all your old paper notes and think about how quickly they break in the weather.
