"As I was running away, I was thinking,'How much is this going to hurt?' and'I hope he goes for my padded arm!'" said Karchut after the training exercise.

The dog did lunge for hispadded arm, soKarchutwas left unscathed.He said it wasamazing to see how dogs and humans can work so closely together with such impressive results.

"The sense of smell on these dogs is tens of thousands of times better than ours," he said."It's hard to even fathom that. I hid a couplethings around a football-sized field at one point and when Const.Johnston's dog was set loose, he literally found them in less than a minute. It blew me away."

Training a police dog

Calgary'straining facilityis in the northeast. It was completely refurbished in 2008 andincludes state-of-the-arthousing, training field areas and mock houses to search through.

Const. Aron Johnston saidthe unit is considered elite.

"We are a specialized section of the service so we're only called in for certain things," he said.

Applicants mustbe in the service for many years to even be considered for the unit. The officers start out as the person the dog is chasing.

"It's a lot of times hiding in dark and coldplaces," said Johnston.

Sophisticated sense of smell

The dogs are a great asset in tracking people and finding drugs due to their sophisticated sense of smell.

"They are able to break individual odours down," he said. "You can take marijuana and put it in oil or peanut butter orsurround it in bounce sheets or whatever you want to do and it makes no difference ... they smell the bounce sheets but they also smell the marijuana."

The dogs are bred by a special breeder in the United States. Johnston says they expect a lot from the animals.

"They have to be able to deal with some our most violent and dangerous situations, but yet go to apicnic with Grade 5 students and go on their belliesand be petted. That's a big reason they live withus at home," he said.

"As soon as you take the harness off and it's calm and there areno sirens going off, and stuff like that, they are just like any normal dog. You wouldn't even know."
