I researched this breed in the course of my dog selection, including going to visit a few breeders, attending shows and talking with owners on message boards, on the street etc.
The general message I got was that they are extremely heavy shedders (like garbage bags full in shedding season), they can be hard to train because they are very independent, some are cuddle bugs/most aloof. Most are highly dog aggressive and I didn’t meet one owner who said they would trust them off leach. They also said they are prey driven, so no cats or small dogs etc.
I met a few that were docile and sweet, and others who were quite intimidating.
Overall I was still in awe of their size and beauty and think that in the right home they would be wonderful. They are very smart, not barky – although some do the “woo woo” or howl. The ones I met were all friendly with people.
I hope someone can address their workability. Since that’s not my forte I didn’t ask too many questions, but I’m sure they are spectacular athletes in their own right.
At the end of the day I had to accept that they weren’t the right dog for me, but I’m sure they are the perfect dog for many!
