BBC NEWS | Americas | Sniffer dogs in teenage bedrooms: "Retired sniffer dogs that have spent years on police patrol are now working in the private sector in the US - sniffing out teenagers' bedrooms.

Parents can rent a dog and handler for $200 (£125) an hour from Sniff Dogs, a firm operating in New Jersey and Ohio.

The dogs are highly trained and can detect illegal drugs.

The company says the animals can smell marijuana from up to 15 feet away (5m) and residue on clothing from drugs smoked two days earlier.

The dogs sit when they detect the drugs but they leave the final inspection to the parents."
