This cute paper toy is the 2008 creation of Shirley-Ann (a.k.a Missy) at the UK website missweblash.com. Missy has two bobblehead robot dogs available for download, this one titled "Rusty Dogbot" and a silver colored version titled "Stoopid Jazbot". The bobblehead action is provided by installing a spring from a retractable ink pen as the dog's neck. Missy's build photo of her Jazbot shows the ears curled and treads attached the opposite of my build, but I kinda like the way mine turned out better. ;) If you want to build one for yourself, you can grab them here and here.
