Back better and stronger! We love these little treat holders, and now improvedand with two different attachments.
 
This brightly coloured caddy is perfect for carrying treats for your dog, saving your pockets from any mess and eliminating the need for hard-to-handle, unfashionable draw string bags. It clips onto your lead for convenience and is ergonomically designed to easily pop open during training. No more broken nails! The TreatCaddy© was designed for dog-lovers, by dog-lovers, to offer the best way to carry your dog’s treats.
I've been using one for a couple of weeks, you can easily hang it off your lead or bag, it  takes aproximately 50G of treats, a great simple design that does a great job!
