just try to get the dog to puke that shit up. you should have done it a long time ago when the dog first ate them. as for the girl with the baking chocolate. all the vets did was made the dog puke that shit up. nothing you cant do in your own home.
1. find your mothers nicest turkey baster
2. fill the turkey baster with hydrogen peroxide
3. pry the dogs mouth open and put the baster to the back of the dogs mouth.
4. spray the hydrogen peroxide. if you get the baster down far enough it will force the dog to swallow
5. put the dog outside and wait 10 mins. dont want the dog to puke all over the house.
those are the steps that my father''s buddy told me to do when my dog killed a box of chocolates. my fathers friend is a vet.
