Par your story points up just how quickly freak accidents can happen. For that reason my dogs are inside when mowing is being done. Years ago a friend of mine told me a very sad story. Her brother had been mowing the lawn and a stone flew out from under the mower, hit the pole on their cyclone fencing and ricocheted back into his eye. It cost him his sight. I know those kind of things are freaky but they do happen.

My two each behave differently around the vacuum cleaner. Bella pays it no attention at all. Ripley often tries to bite at the light and barks. LOL!
