GEORGETOWN – Sniffer dogs are being blamed for airport security lapses in Guyana, where police said Monday that their canines are too old or not skilled enough to detect drugs stuffed inside suitcases.Police are preparing to buy and train new animals to replace the force’s three sniffer dogs – two at the main international airport and one at police headquarters, police chief Henry Greene said.The government began a security review last week after United States officials complained about a large number of cocaine-filled suitcases from Guyana intercepted in American cities. One suitcase seized last month at New York’s John F. Kennedy International Airport contained 50 pounds of cocaine.The dogs’ handler, Maurice Smith, said the animals – two Labradors and a German shepherd – would be more effective if officials provided cocaine as part of their training.
