Dino does bark every now and then ... still very much puppy sound but he does have the potential for deep-bark in due time
Otherwise, I will have him eat plenty of chilli then

Dino's drive ...
Well, I have no much comments on this yet as Dino has his own style of attitude that doing his own thing at his own wish but his litter-mate - Draga is well respond by far 
Yes Draga responded very well to any "stimulus", from an early start, while Dino just wanted to be boss and do things because he wanted to maintain his position, not because he loves to work.
Just to add - Happy was like that at first, very independent and "silly" in a way, but in the end Dux was able to train him, no problemo. Actually, I just asked Dux to make sure he calls me for another video session before Happy goes back home (upon training completion)
ps - I am expecting Dino to be very good in protection, once he understands the concept of a "threat".. but time will tell...
