Dog park, trail walk, or beach run - your dog comes with you everywhere, and there is always some dog poop to be picked up. The Tailgate Dumpster is designed for the dog owner on-the-go. The silicone holder attaches to the back of your vehicle with super strong magnets. This Kurgo doggy bags holder allows you to store your dog trash bags on the exterior of your car rather than in the car, or hanging it from the rear wiper blade. Once home, the dog bag holder detaches easily so you can dispose of the mess and move on to your next adventure! Approximately 5.9" L x 6.2"W x 2.9" D. Note: This is a magnetic product and will only adhere to metal surfaces and will not work on aluminum or fiberglass. Most bumpers and some large SUVs and trucks have rear doors made of fiberglass or aluminum. For trucks, attach on the inside of the tailgate for security, wind flow may blow it off the outside of the tailgate.
