Police canines are awesome! They have the ability to break down and eliminate odors which allows them to be trained to indicate on specific odors such as narcotics. The great thing is they don’t see this as work what they know is when they successfully indicate an odor for which they have been trained a ball magically appears and they get to play! Many different dogs are featured here indicating the presence of an odor at this printer that in fact contained marijuana. One picture shows that moment that dogs dream about when the ball magically appears falling from the sky!
