I recently adopted a 4year old dog from the RSPCA and I love him dearly. It quickly became obvious that he definitely had lead aggression issues and no lead manners whatsoever. I don,t know his background but from his behaviour i assumed that he had not been taken out much whether his former owner couldn,t be bothered or whether his behaviour had made it too difficult i don't know. I have invested a lot of money which I can't really afford on one to one lessons with a dog behaviourist for the last 4 months and it has made not a jot of difference. Then it occurred to me that dogs have been living with man for thousands of years without the benefits of all these experts and I thought back to dogs i had as a kid who never had a training class in their life and had lived long and happy lives with my family. I have done my own thing for the last two weeks including correcting bad behaviour, using a slip lead and not tolerating his bad habits and not using only positive rewards. I have no axe to grind but would just like to tell others that his ingrained habits have been turned around. Walking him has become a pleasure and he is much calmer knowing i am in charge. I am so glad I listened to my gut and just applied a little horse sense.
