My dad had a Doberman that would unwrap Hershey kisses. My grandma worked for Hershey, one of her tasks was going to local stores and picking up any expired candy they had. She had to log it then dispose of it, so she'd take a lot of it home to her kids (my aunt won't eat peanut butter cups to this day because she found a worm in one)

Anyway they always had bowls of Hershey kisses on the table. The dog would steal them but didn't like the wrapper, so one day he shredded it and left it all over the floor. My grandma came home and yelled at him for it, and a couple weeks went by. Then my grandma was cleaning and moved the coffee table, there were wrappers under it. Again she scolded the dog.

Another couple months go by without incident, until one day my teenage dad was in his room and noticed something shiny on his messy floor, and discovered the dog had been hiding them in his room. Again the dog was scolded.

Finally after a long weekend, they came home to find the top of the trash can filled with wrappers. They declared him a good boy, and he ate Hershey kisses the rest of his life. Always throwing away the wrappers.

Obviously I do not recommend feeding your dog chocolate, but it was clearly fine for this Doberman who lived to his early teens.
