Oh really? I am sorry to hear that. But isn't there room for a second opinion or something like that? Our first labrador was really a pain in the but... Demolished for thousands of euro's at our home. He was neglected by his first owners, we thought he wasn't 'repairable' untill we found a trainer who trained in somewhat radical way. But for that dog it did help, he needed a other way of training then most dogs... but luky for us and for him, that worked really well. I was convinced the dog had a problem which wasn't us but a heritage from it's first months in his life... I wouldn't let him down as his first owners had done. The training was intense, for two months every single evening training at the dog-school... But after that he was really the most sweetest dog we ever had....
