If your dog is like mine, or really any dog, they love their squeaky toy. Do you know why dogs love the sound of squeaky toys?
Our dogs descended from wolves and are not too far removed from the traits and behavior of a wolf. In the wild when wolves eat a small animal like a rabbit, they instinctually will hear the animal suffer or squeak. This sets in motion receptors in the wolf/dogs brain that signals it is feeding time.
For many dogs the squeaky toy does two two things in my opinion, delivers instinctual responses from hunting and to get our attention.
