@kathryns.canines: 12 week old, Preti, working the scent wall! Her target odor, UDC, is in port 8. There are distractors in ports 3, 5, and 16. Preti is starting to show her alert - my criteria is a stare at odor, Preti had decided she would also like to sit! #labrador #k9 #puppy #puppyintraining #workingdog
