Mary just needed a few small items from the grocery store. It was a beautiful day, the sun was shining, the air was crisp, not a cloud in sight. So, she said goodbye to her husband and their kids, and headed out the door of their home for a brisk walk to the store. Just an hour away from two young children and a husband whose afternoon sandwich had used up the last of the turkey breast, bread, and mayonnaise in the house… gotta get some more before it's time to get dinner started, because there'd be no time later that evening.

Unfortunately, Mary chose the same time for her jaunt to the market as when her neighbor Suzie was leaving to walk Fang and Kidney, her two English mastiffs. As Mary walked past the dogs, they pulled free from Suzie's grip on their leashes, and set upon her. The leashed dogs – with a combined weight of 233 pounds – mauled Mary for about five minutes before Suzie could pull them back into her place.

Suzie was injured in her valiant effort to stop Fang and Kidney, but Mary died four hours later, after being rushed to the hospital by paramedics who performed CPR on her in a vain hope to restore a heartbeat. Surgeons spent almost two hours repairing the veins and arteries of her neck. Some of wounds were 1 1/2 inches deep, and doctors had to insert a tube into her throat to support her trachea. She remained in "very critical" condition for 70 minutes after surgery before dying.

This might never have happened if Mary – knowing these two powerful attack dogs lived next door – had carried an electronic dog repeller with her when she walked out the door that day. Using the latest ultrasonic technology, the Dog Chaser produces a discomforting but not harmful, high frequency sound, audible to dogs but not to humans. This scares off the approach of unwanted dogs at up to 15 feet! Save your family!
