"Technically, Ody is not a pit bull but a crossbreed of the American Pit Bull Terrier and the Staffordshire Terrier." So what dog show did you enter him? And win what? He's a mutt. Unless you are competing in agility, obedience or some other such dog competition, to me a "dog show" is a show that is typically a conformation show. A conformation show is one at which purebred dogs are evaluated to determine their degree of adherence to the breed standard (the "blueprint" of the breed which is determined by the breed club).
"The accusation was that Ody, chained to his front porch, was chasing pedestrians off the sidewalk. Zeitler said it could not have happened because the chain wasn’t long enough." You have him chained? Nice. How many attacks have happened from dogs chained?
Looks like the city plans to keep the ban as is.
