Not A Hot Weather Dog?

I guess it's been a few days already since I posted.  It's been a VERY strange stretch of weather, it's March and it's HOT.  80 and humid!  40 degrees over average and dewpoints in the 60s.  And Shasta has not thought highly of the temps, she is panting pretty easily and lying only on tile the last two days.

We have an in-town show this weekend and today Shasta showed fear for the first time.  I took her outside to pee and as we were walking back in a motorcycle with an intentionally loud muffler drove up behind us.  Little Shasta hit the end of the leash with ears back.  Sadly I didn't have any treats with me but after a few seconds she settled and I let her watch it for about 5 seconds as it drove past us and we went inside.  Later we were back outside with quieter motorcycles 50-100 feet away or so and she didn't react at all.  This motorcycle was LOUD, can't say I really blame her. 

As for training, still going really well.  Last night she was hot and tired, she wasn't as intense but trained some.  Tonight we actually turned the a/c on a little and she was back to being a little nuts about our little training session.  Her down is now going very well.  The sit is going pretty well although right now I think she thinks it's jump up and then go down into the sit.  As for the beverage tray, it took about three sessions but she was somewhat reliably putting her two back feet on the tray, two front feet on the ground and holding it for about a second.

She also spent more time a few nights ago again with the large tennis ball and she was loving it.
