In honor of Halloween we did totally blind searches, meaning in total darkness (as we've done for the last two years at this time). Handlers and dogs wore little glow stick necklaces, so you could see where they were. There were also glow sticks on the floor and near the hides, so you could get a small sense of what was going on. Obviously no videos.
Interior 1 - Four hides in the dark. Gimme moved around at very close to her normal speed. There was no sign of the dark being a hindrance. Of course, the superior night vision of animals is well known and given how she searched it certainly seems true.
Interior 2 - The 4 hides were all moved, but Gimme still found them quickly. This was much easier for her than it was for me - I walked into a couple chairs.
Interior 3 - One odor-bomb hide, placed under a table, inside a couple of ex-pens, with some chairs and other obstacles. There were three ways in, but they weren't obvious even when the lights were on. Gimme very quickly found the scent and sniffed all the way around the puzzle. Then she left the it, taking a quick tour of the room, scanning for an easier hide. After the 20 second room scan she came back to the puzzle and quickly found her way in to the hide. One curious thing - all the dogs went in whatever way they found and then exited one of the other ways. Not one of them retraced their route to get out of the puzzle.
It was clear they weren't hampered by the darkness.
Since then I've submitted our level 5 parkour entries to All Dogs Parkour. I should get the results soon (last time I submitted it only took five days). When it comes Gimme will have titles #28 and #29. Meanwhile I've already taped the behaviors for our level 1 entries toward her parkour Grand Championship. This will be our 30th title, my goal for this year. We'll need ten more entries to get the GC.
