This new and improved version has 2 strong carabineers (one on each side) and bigger front pockets to fit the larger sized phones (pocket size is 16cm x 9cm and fits the new iPhone 6 new Galaxy S) plus more treats. The Walkie Belt sits neatly and tightly on your hips so you hardly know you re wearing it and best of all it looks much more stylish than a bum bag. Use it for running with Fido going out for coffee with your doggie friends or just for a casual walk to the park. Just hang it at your front door with a spare house key in the front pocket and all you need to grab as you leave the house is your dog. Genius Size: extends from 70cm (womens size 4) to 130cm (womens size 20).
