Tonight was the first time I have ever bitched someone out in public.
There is large dog in my neighborhood named Chester. Chester’s owners never have him on a leash. Ever.
I used to let my dogs out in the back of my building without a leash late at night. After a very bad incident I learned that a dog fight will start regardless of how nice your dogs are. If the leashed dog is vicious then your dog will respond. A leashed dog is also more likely to assume an unleashed dog is a threat and the ensuing drama is ALWAYS the fault of the owner of the unleashed dog.
