An insurance company is revealing damages done by man's best friend. London-based Aviva said it receives an average of about 800 accidental damage claims each year involving dogs. One of the most noteworthy claims it received involved a Labrador/Great Dane mix causing more than five-thousand-dollars worth of flood damage after it turned on a water tap in its owner's kitchen. Others included a dog knocking over a TV after getting excited about seeing another dog and one pup who spilled bleach on carpet.
