There is a guy close to me who has one.
He doesn’t use it for work but he has a mad interest in dogs and especially unusual breeds.
From what I can gather from several conversations,
He paid an astronomical amount for the pup
He has had/still has lots of issues with her aged just over 2yr old, training has not been easy nor straightforward.
She seems to be quite hardy and healthy from a physical point, but mentally not as stable as had been hoped.
From my point on meeting her, nothing special, not particularly a good looking breed imo, certainly not bidable nor steady.
I’ve seen this guys other dogs and been around them, all of which I trust, and know he is able to train dogs, but this one, just doesn’t seem to be the same.
Of course, all the above may well just be this particular dogs character, but is enough to put me off getting involved with one, and I’m used to the malinois breed !
