70lb dog ate four Reese cups. Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 2 years and 7 months old | 70 lbs

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Prince. Oh no, that's not good! As I'm sure you know, Reese's contain chocolate and chocolate is toxic to dogs. At 70lbs of body weight, he can eat about 30 average size peanut butter cups without suffering chocolate intoxication; however he may get gastro-intestinal problems such as diarrhea and pancreatitis. Fatty foods can give dogs pancreatitis, which can be life threatening. The best thing to do is take him into the vet to have vomiting induced to get rid of the peanut cups. If you chose not to do this, you need to watch him for vomiting, diarrhea, vomiting undigested food, lethargy, a loss of appetite, and vomiting water. If you see any of those signs, it's an emergency and he will have to see a vet right away. I hope this helps!
