Dead Dog!

While I was away the children, for some reason, loved to go into my room. They'd get into my bed, play with my models and all the bits and pieces lying around, including my doggy money box.
You put a coin into the dogs bowl and he starts moving around as if eating out of the bowl.
A couple of the wires had been pulled loose so I tried to solder them back but didn't know the order. Just couldn't get it right and he's no longer working. Well, he does do the action but doesn't stop so is continually 'eating'.
I'm afraid I have a dead money box dog on my hands but I can still put the pound coins in that I save up to give people at Christmas.
This is what he's supposed to do!
