I'm glad your dog is feeling better.
FYI dog lovers out there, my 85 lb lab is a chocoholic and lives to bark about it. I did read once it's the dark chocolate that's dangerous, and milk chocolate doesn't have the same strength of toxins. Now foil wrappers are another story.
BUT... I am notorious for stocking up on candy after every holiday when it goes 50-75% off. Of course it never lasts as long as I tell the cashier it will

, but I do buy a lot sometimes. Lets just say my dog would find you in the 100 acre woods IF you had a candy bar in your pocket!!

He got into my bedroom closet while we gone and ate two whole plastic Target bags full of chocolate eggs/kisses, Marshmellow eggs, and Cadbury Creme eggs (my favorite

)!! We did have a day of throwing up wrappers and such, but no signs of poisoning. He has done similar stunts a few times, that was the worst, and most of the time we don't have to suffer through clean up duties. He even had a whole 12 oz bag of semi sweet choc chips I forgot in the grocery bag and didn't get put away before leaving the house. I was not happy. This IS the dog who has to wear an electric collar to keep him OUT of the kitchen because he opens the bread drawer, freezer, refrigerator (even if blocked by chairs) oven and toaster oven. We're toast if he figures out the pantry!!
A yorkie or such of course couldn't handle the amounts of a large Lab, but don't panic over a few pieces of candy. A call to the vet can't hurt of course.
