Dogs can be just like family members to many of us. We would never want to knowingly or unknowingly feed them anything that would cause harm. This is why it's important to think twice before you feed your dog any leftovers from your plate or any other source not intended for dogs. Fido may be man's best friend but he's still not a man. Many of the foods that are healthy for us are dangerous for our canine friends to consume because biologically man and his canine friend are very different from each other.
