"To Leash Their Own" 8-Pack of Slip-on Style Dog Leashes in Rainbow Colors. Eight pet- and earth-friendly ways to step out in style every day of the week (plus one). We made our Slip-on Style Dog Leashes with both your pet and the planet in mind: By using upcycled polypropylene, we took plastic waste material out of the environment and transformed it into a super-chic, colorful, any-occasion leash. Mix and match with our dog hoodies and T-shirts! Each features an easy slip-on design for total convenience and an integrated handle loop that fits comfortably in your hand, giving you a secure grip—even for dogs that pull. With a length of 6 feet, our Slip-On Dog Leash offers ample freedom for your pet to roam while staying close by your side. Whether you need some color in your daily walks, want to match your pup, or your little lady just had a new litter (congratulations!), our 8-pack is ready to kick up your leash game.
