Liesel Weapon : WEEK 8 of the Top Tier K9 working dog puppy imprinting program. NOSEWORK. Liesel Weapon has a god given gift of excellent scent detection (and stellar breeding ;) ). She is killing her tracks and field searches with scented toys. We have moved the searches indoors and the game continues. This week also marked her last round of puppy shots! That means she can go and walk anywhere without concern of catching anything nasty...first stop! Ace Hardware in Missoula...
