I am doing ring craft classes with Roxy at the moment, I don't know yet if I will show her, it depends, but anyhow even if I won't show her, ring craft classes are good for her socializing. So she is doing ok, but I can't figure out how to bring her tail up more often!?! She stands very nicely, but as soon as say "stand" (bait) her tail goes down. I have tried talking to her, cheering her up, bringing all kind of toys, different treats, even singing LOL but her tail stays down

And the same with walking

I think she doesn't like the floor in that building, it's like very cold concrete, last week they had some carpet and her tail was up a little bit
When we go for a walk her tail is up most of the time, especially when she is on the grass

Oh and when a stranger starts talking to her she is wagging her tail like crazy LOL
Are there any tricks how to teach her nice "bait" with her tail up?
Thank you!!!
