(Newser) – Strict Japanese rules against importing dogs are holding up canine teams that could be critical in rescuing survivors of the nation's massive quake. A Swiss team of 25 handlers and nine dogs has already been delayed, and US officials are negotiating with Japan to speed the movement of search-and-rescue dog teams from Virginia and California. "There are many rules here, so it's taking a long time," a frustrated member of the Swiss team told ABC News.
