Postal workers across Iowa face the threat of dog bites every day, but the U-S Postal Service is focusing on the threat of children being bitten by dogs. Postal service spokesman Jim Stanley says kids are 900-times more likely to be nipped by a dog than letter carriers, but he adds, the contentious relationship between dogs and postal workers is very real. Stanley says “I had a couple dog experiences that made the hair rise on my neck. It’s not mythological.” Four-point-seven million Americans were attacked by dogs in 2003. Almost three-million of them were children. Stanley says some people are surprised to hear that letter carriers are -not- the demographic most likely to be bitten by a dog. Stanley says letter carriers are asking people to think about dog safety involving children. Experts say if approached by a lone dog, stand still with your arms crossed.
