Dog treat bag with additional pockets to hold supplies such as cell phone and dog training aids. Pouch can be worn over chest or across back for backpacking. To adjust shoulder strap use slider buckle to fit your size; bag is reversible and no adjustment is needed to wear over chest or back. The material is waterproof but not submersible due to zippers. However using for water sports such as kayaking or adventures that may get you wet the pouch will keep the contents dry. Pouch is roomy enough to hold treats in a zipper pocket as well as any training aids, small dog toys and leash. The front pocket is very roomy and can be used for dual purposes; dispensing treats as well as to dispense poop bags. This will dispense bags one at a time and will replace using a poop bag capsule which usually fall off leash or break. In addition is a side pocket to hold a water bottle; this pocket will hold a bottle up to 4 inch diameter. There are added D-Rings to attach a dog whistle, clicker or a collapsible dog bowl. This pouch IS NOT designed to attach dog to D-Rings! If you are a dog owner and are looking for a pouch to carry treats and supplies this is a great addition for dog parks, hiking and daily dog walking. This is a daily use unisex bag.
