Hey Mikael ,
very cool video , i really like it !
May be i can train my new Csv to learn it ? It might be possible, he´s just become only four months old and i think he still is very flexible...
Would be funny to use this movement of showing his backbone to some people who are worth for it ??
Please tell me if you have been successfull in teaching this to YOUR Csv !
Have a nice evening .
