Poor Punkn! Well, the good news, if there is any, is that crayons aren't terribly toxic bc kids eat them all the time. It could be different for pups, but I can't imagine they'd be severly toxic unless they became stuck in their systems.
You might try giving some Pepto to calm his tummy and give Pedialyte bc he's probably getting dehydrated quickly, which can be dangerous. Perhaps try giving him a bit of soda cracker as well. Just make sure he is getting water.
How old is he and what is his weight?
