So true; I likely came close to losing my black lab back in 1999 when as a weekend caregiver I was out shopping when the lady passed away. A neighbor had called for a welfare check and when EMS arrived, they found my lab guarding her. Luckily I returned back shortly after they arrived and before the police took down the dog. I immediately took him and put him in my car where he was safe. The house was put off limits to all until the medical examiner arrived to investigate.
Thank God your dog was spared!
