Male Australian Shepherd Off-Leash Problems (Attacking Other Males Who Are On-Leash)
My 1 year old male Australian Shepherd is very intelligent and he has learnt that he can experience the thrill of "winning" when he spots other male dogs who are on leash. When he spots one, he will start barking and lunging at these dogs.
Normally his recall is very good but he has now figured out that it's fun to feel this "winning" experience. He is chemically castrated but is very dominant.
To be clear, this is happening in off-leash parks and it happens to be with owners who have males that they are very nervous about and for whatever reason walk them on leash in areas with dogs off leash. I have noticed these are typically smaller but very equally dominant males that my dog can bully can experience this thrill.
Its maybe happened once or twice in the last 6 months but today it happened twice in two different parks.
How do you resolve this? Do you just work on better recall or is there anyone that has experience solving this issue?
