I agree that dog owners can be very rude and inconsiderate of others when they allow their dogs to be a nuance - whether it's not picking up their mess, letting them bark, letting them run off leash, or other "dogs will be dogs" sorta things.
The title of your thread hits the nail on the head - the dogs are good dogs and are just bein' dogs, but it's the owners who are RUDE.
