The idea of K9 Units for the Eng. has been proposed for years for Mine Clearance,one of the excuses for not implementing the idea "it's too cruel on old Odie" and what ever other excuse's they can come up with.
Here in Vancouver there is a Center for training dog's for the N.G.O.'s involved with Mine Clearance.
They get some of their dog's from the pound.
I would rather see the dog's used in this way instead of being put down at least they get some one who cares about them.
K9 Units are a good idea,work well and are cost effective.
