Wrap Hershey chocolate nuggets in enough ground beef to produce a 1/2" wall
around the chocolate.

I understand chocolate does quite a number on dogs.

Not so's you notice. My dog ate about half of one of those 8" solid chocolate
easter bunnies and put the rest away for later. It didn't hurt him.
On the other hand dog owners might take a shot at you if they see you trying to
poison their dog. It only takes one dog owner to hang the jury.
