I just saw this too, and I'm sorry Autumn isn't feeling well.
I know my girls have eaten things they shouldn't even when I'm standing next to them. They are just so fast and they immediately run and hide!
Do you have a cat? I have found my cat aids and abets when it comes to the Yorkies. He'll actually get into the trash and drop bones on the floor for them to eat. I have to empty my trash immediately if there are bones or shells in there.
Good luck and keep us posted!
