Zara. V. Z Huckelovy Von-Zito review: Dog breeder

I purchased a Belgian Malinois from Bernard Julien of Zara. v. z huckelovy Von-Zito in October of 2020. The name of the website is Von-Zito Belgian Malinois. He is also on the AKC webpage having another litter listed and It looks like he may be over breeding his dog. As for our pup, at seven months my pup started to act out with biting and being a little aggressive, around 1 year he was still having the same behavior, but it seemed to be getting more frequent. I emailed this breeder (Bernard Julien) and asked if anyone else from the litter was having issues like we were. He said no and that we should try using a E-colar. We have taken our boy to three different trainer including a board and train for biting and aggression. Only to have the worst outcome to put him down due to his behavior. My last trainer said they had found a women that had got a Belgian Malinois from the same breeder and had the same issues with the same end result. We don't want this to keep happening to people purchasing a dog to love and then have their hearts crushed. This breeder needs to be investigated.
