The last doggy bag I bought on Ebay turned out to be a lot larger that I thought. Well, another wasted purchase, I thought. Low and behold I find this bag works great as a gym bag for the water aerobics class I take. The air vents work great for keeping the wet items from smelling moldy (I don't always get around to emptying my bag right away). so, you didn't buy another doggy bag, you bought an all purpose tote. You just never know when a vented bag will come in handy.
