LONDON, July 6 (UPI) -- British police say they are writing guidelines advising officers to put bootees on sniffer dogs upon entering Muslim homes to respect the religion's tenants.

The Association of Chief Police Officers is making guidelines stressing the importance of religious awareness when bringing dogs into buildings to find bombs and drugs, The Sunday Times of London reported.

Dogs are referred to as "unclean" by some Islamic injunctions.

The parameters, to be published within the year, were initially made to protect mosques, but were broadened to cover other types of buildings, the Times said.

"We are trying to ensure that police forces are aware of sensitivities that people can have with the dogs to make sure they are not going against any religious or cultural element within people's homes," an association spokesperson said.
