GSD? Yes.
They are trained to protect rather than kill though, you can see it in their behaviour clearly.
Even with them you can see the wolf coming through at times; i remember the time my first one met a small flock of sheep well.
I have seen my fair share of anti-social GSD. An ex mother in law was a breeder.
If the GSD had the same numbers of completely unsuitable owners then we would probably see horror stories in the press relating to GSD. As an intelligent breed, with lots of drive, they can be trained to be many things. One man’s protection dog is another man’s attack dog. This can be applied to Belgian Malinois, Black Russian Terrier, Rottweiler, Akita, Mastiffs, Kangal, Cane Corso, Doberman etc
I have been following this XL Bully trend for sometime as a guy I coach is a dog handler. He picks up abandoned dogs, strays, dogs that have bitten. He has handled many XL Bully “type”, and he says many have been ok. But he also says many are not, probably due to lack of socialisation, training, nurture, stimulation and unfortunately some do have an inherently aggressive streak. That is HIS experience of the breed. He says there have been a couple he would have happily adopted, but numerous he would have no qualms about being put to sleep as they could never be trusted. He has been bitten twice in the last year, once by a XL and once by an Akita. The Akita was just a hateful creature, whereas the XL greeted him into his pen everyday then one day it just decided to attack him. Make of that what you will.
He shared one story about an XL that beggars belief. Early in 2023 he got called out to collect an XL that had bitten its owner, when I say bitten....the guy had his arm or part of it amputated. Within a week the owner stated he wanted his prize stud dog back. The police apparently went along with this, and months later the dog went back. About two-three weeks ago the handler was called out to collect an XL that had bitten a teenager and another child. The child suffered a bite that went down to the bone, and the arm was broken. The dog greeted the handler happily, because it recognised him from months being spent in the kennels before unbelievably being returned to the one armed owner. Blame and fault can be laid at a number of doors with this but jeez....we have some stupid laws and many stupid owners of dogs that have massive potential for inflicting damage.
