Protective Dog

MZ_Angie, I have never known a dog that wouldn't be protective when necessary. I had a Lab that was the sweetest, lazy dog. Loved everybody. But, come on our porch uninvited and she would tear into you if given the chance.

Louise, I think you may be right that the dog was scared or startled by the mother's voice. It may have been reacting to the volume and tenor of the voice rather than who was saying the words.
