I had exacly the same problem as Winnie (Leash Aggression) with my older male Kelpie x. Believe me the problem does not get better until you get some professional help with someone that specialises in these types of cases. I tried everything with my dog even the obedience clubs that were offered in my area but i found that they didnt help the problem at all, in fact it made my dog worse because he was so stressed and frustrated. I tried putting my dog on a halti and also attempted muzzelling when i did take him for a walk. But in the end i didnt want to take him anywhere and he hated the walk due to the muzzell.
I was at my wits end especially when my dog slipped his collar and ran towards another dog.
I decided that i needed some proffessional help and so i rang Vern Ryan as i heard he dealt with these types of issues (Aggression) I was unable to do one of his courses so i decided to have a private lesson with Vern.
He taught me socialised walking with my dog, this is where my dog learnt how to walk on a loose lead, therefore he would relax.
I read comments posted that he trains negatively instead of positively! That i would like to say is totally incorrect. Yes he does use correction collars but if you know how to use them properly then you should never have to use them at all.
Vern Taught me the importance of interpreting my dogs body language and also to constantly talk and praise my dog in a positive way. By telling him what a good dog he was when he was behaving in a way that was acceptable.
My dog reponded well to the techniques used and by the end of my lesson my once leash aggressive dog was happily walking past another dog and not batting an eyelid and most importantly on a loose lead.
I am now 100% confident with my dog that i can take him anywhere and know that i have full control over him, he is a much happier dog who enjoys walking and going out and Most importantly i am back in control and a much happy and confident owner.
I would like to thank Vern Ryan for his expertise and guidance in helping to re-train my dog.
Also i would like to comment on the point made by another member about mixed breed dogs. My dog is a mixed breed and there is nothing wrong with him nor is there anything wrong with any other mixed breed.
I suggest you do some research and find out where most dogs originated from and im sure you will find that they were developed through cross breeding.
Maybe you should be looking closer at your own mentality.
