It doesn't seem that long ago that Tika wouldn't stay at the start line, flew off her contacts, ran off during class to chase squirrels--she has been a delight last week and this week in class. Again, she started to dash away from me a couple of times but came back almost immediately when I called her. I was having some rough times with my body language on some interesting rear crosses in class today and kept mucking up, and she was very patient with me. Kept coming back for more instead of starting to sniff (displacement) or heading off after squirrels. What an excellent beast.
She's still standing up at the start line, though. Instructor pointed out that she's done it just after I've given her a treat for sitting, and also suggested that I might try walking around behind her first and then walking away. So the last two runs I didn't give her a goodie just before leaving her, and one time I walked behind her and the other time I stepped away from her laterally before going forward, and both times she stayed in the sit. So that might help.
