My 5 year old desexed GSDx Caleb was a rescue dog that we adopted when he was 5 months old. When we got him he was scared of everything: people, dogs, unknown places - you name it, he was frightened of it. With a lot of work, we got him to the point where people were great and he would play with other dogs , although Rory our beagle had to play with the dog first before he would join in. Then our offlead dog park got closed down and straight after that we had three incidents where Caleb was harassed and threatened by off lead and out of control dogs. Caleb went from being a dog who would greet and play with other dogs to a dog that would growl and threaten other dogs. This was about three years ago. During that time, we have managed to get Caleb to the point where he can see another dog without his hackles going up, but we are still nowhere near getting Caleb relaxed enough to meet other dog let alone play with one.
I don't want to move to the point of letting Caleb interact with other dogs without professional help. So much could go wrong and I would never forgive myself if he hurt another dog.
Therefore, I need recommendations of trainers/behaviourists that have a lot of experience working with aggressive dogs and that train by use of positive reinforcement. Does anyone know of any in the Sydney area?
