We all love our dogs, and we love seeing our dogs happy. A very easy way to make them happy is to share a little bit of whatever we're eating with them. However a dog can have a very different reaction to certain foods and chemicals than a person, and some foods that are harmless or even healthy for us to eat as people can make our dogs sick and even kill them. Before we open up our fridges and pantries to let our four-legged best friends feast upon the innards, as responsible pet owners we need to know which of our favorite foods are so dangerous that we should just eat them ourselves.
