Why should all dogs be muzzled in public places, Daffy. Should all people be handcuffed and muzzled in public places too. At 65 years old and owning dogs for years, and years none of my dogs has even bitten anybody. I am more frightened of some people than of dogs. Dangerous dogs should not be out in public places, and there is a good case for muzzles, but why should all dogs suffer (and they do suffer when they are muzzled) because of the very few that cause problems.
I don't think dogs should be muzzled because some people are terrified of dogs. That is the problem of those people, not the fault of the dogs.
