It´s not a trick, the dog started to do this as a puppy as it did not like to walk on cold snow
normally this dogs breeds has one paw in the air, but this dog was (smarter)
Noooo, Hronec cant do that
And CsV do not need to do this, as they as suitable for cold climates
Even -40´C
But this far I only tested Hronec in -25´C as I live not so far up, I live in the Stockholm area...
