Understanding "Leash Aggression" in Otherwise Friendly Dogs
Why otherwise friendly dogs may behave aggressively when on-leash.
If you hang around with other dog owners, youve no doubt heard the same comment I have, over and over again: My dog is fine with other dogs when hes off-leash; hes only dog-aggressive when his leash is on. You may have even said it yourself. The reason its an often-heard comment is that its a common behavior: A lot of dogs who are fine with other dogs when left to their own devices become aggressive if they are leashed when they meet other dogs.
