Hey there, I have rescued a 5 Month Old german shepherd husky mix tjat er Sound on the side of the Road in the US. Er have brother hun back to Canada now and i am having a bit of trouble teaching him. He has been running off leash now for a while and would come back with ease and was always greated by a over the top good boy and pets and cuddles or with a really tasty treat as a reward. This behaviour was what we were wanting in him. All of the sudden he started to not be coming back the way we wanted to and would run off. We tried walking the other way to see if he would stay near him family and come back, we tried being over excited with treats ready and the usual call and whistle, nothing works when he has his mind on something else. A trainer told us to grab him when he comes back by the scruff of his neck and say NO and put him back on the leash. This i think has worked opposite for us as he is now scarred of me so when I let him off the leash and call from him to come back with “Kota, Come!” In a nice voice he will stop and look at me and I will say it again “Kota, Come!” And he will run the opposite way. I don’t know if he knows what he is doing wrong of if he has now associated “Kota, Come!” With being hurt... how can I fix this behaviour? I feel aweful and don’t want to hurt my dog and I want to love him and for him to love me but I want him to come back if I’m being serious if there is something that is going to unhurt him, a car or something in traffic. Should I not use the scruff of his neck anymore and should I just make him stay on the leash for now until he gets that under control? We rescued him when he was 4 Months old. (The vet thinks) and he is 5 months old now. Any advice helps! Thank you so much in advance.
