There's all this fuss over feeding dogs chocolate and how it can be harmful and even fatal.
I had never heard of this growing up and we never had a problem all the years we had dogs, but looking back I cannot remember a time any of our dogs would've eaten chocolate (we were much too concerned with consuming it ourselves than to let our dogs get a hold of it!).
Is it true that chocolate can be harmful for dogs, and if so, why?
Is it harmful for puppies, or are they different?
