on whether sniffer dogs would be offensive to their religion. And there is no way to resolve this since there isn't an overall Muslim leader or group of leaders.

Aside from that issue, however, sniffer dogs and their trainers are very expensive and can't work more than a few hours at a time before the dog loses interest. The cost of hiring enough dog teams to cover 24 hr. shifts at all our airports would be prohibitively expensive -- even if that many trained dogs were available, which they are not.
