Ok I won't call the issue fixed, but Miss Z kicked butt in the little and not so little runaways we slipped in with DH before the sun went down.
This go round I didn't mark anything with the scents I have, but we worked in a brushy field near our house full of debris and I'm sure frequented by many critters.
Run 1: 50 ft through tall grass and over a rolling hillock. Found DH and had issues on the refind, likely because this was the first time he used *tuna brownies* instead of regular boring dog treats lol. She started to come to me about 3 or 4 times, but kept looping back to him, but did finally come to me, do a nice alert, got a reward and ran back to DH lickety split.
Run 2: A good 80-100 ft through briars (oops) and ending behind a pile of timber and brush. Found DH and did a NICE refind, complete with VERY enthusiastic alert. Not a flinch as she plowed through the briars and navigated them well on her way back during the refind, maintaining motivation nicely.
Run 3: A massive 500-550 ft run over fallen timber, through grass and briars and ending with DH behind a small shack. Crazy fast "Go Search", an amazing, spot on, uber-hyped refind with me at roughly 250 ft away from the "victim" sans all extra cues and with a nice alert. That little dog can MOVE when she wants to! This occurred after she seemed interested in another direction as DH was walking away, which usually results in a less enthusiastic take off, but we blew that thought out of the water tonight. Very cool!
