This is the classic war poster "Keep Calm and Carry On" reworded to "Keep Calm and Walk The Dog". There are silhouettes of dogs standing and sitting on and around the words. The design makes great presents or gifts for dog owners/lovers, or as a thank you for kennels/vets/rescue centers.
I've put this on a green background, but you can change that really easily. Hit 'Customize it' and then 'edit', and you'll be able to change to absolutely ANY color you prefer.
