My personal experience with my first wolfdog was that when he was left alone at home, he destroyed literally EVERYTHING.
I think I spent at least 4.000 euros to repair all the damage made by him.
He had what they call "anxiety of abandon" or something like that.
Wolfdogs feel a lot the pack, and hate being alone.
They tend to express their feelings destroying objects.
When he was 1.5 years, we took our female, Lunatica Crying Wolf.
Never again did I have any problem at all with him, never.
For me it was:
1 CSW=chaos
2 CSW=pack=the male is never alone=end of damage
Maybe mine is an exception but it's the truth.
As for obedience, I really cannot complain about them, and being the first one quite obedient but not very snappy when obeying, the experience taught me to change method and the second is really much better.
ah...some photos to prove some damage!!
