I would totally take him in to the Vet, just to be safe, and watch him for the next few days. cooked bones can be very very harmful to the digestive system. hopefully, because he ate all that meat with it, the bones won't rip his stomach or his intestines. for future reference, it's a good idea to feed him bread right after eating cooked bones, as it can protect the digestive tract from the bones.

Fozzie is crafty like that, too! He some how jumped onto a stool at the other side of our kitchen counter (which are high stools), and walked around the whole counter to the other side and ate a baguette & a whole stick of butter. including the paper around the butter. and I almost cried because I had just bought that baguette from La Bou. >;[ but, yeah, leaving cooked bones anywhere - even in the trash can - is scary & should be avoided next time! good luck with your Golden, I hope he's fine!
