"A year and another dog later, we still love the doggie dooley!! I swear it is the best invention in petcare. We have the prism system, but it wouldn't let me do another review on that product. We initially had 2 dogs, but inherited a 3rd this past February. They weigh 13, 19, and 55 lbs. The doggie dooley is still handling the waste well. Our soid drains fast, but it still digests. In fact, we sometimes forget to add water daily. It still works. As far as odor, I haven't noticed anything major. Of course when you open it to deposit new waste, there may be a whiff; however, but it is very minor compared to poo in baggies. As long as the lid stays closed, there is no odor. We love it, love it, LOVE IT!!"
