I like DNA identification as a permanent and secure way to identify the dog and owner. How-ever at this point in time, microchipping while not perfect is a reasonable alternative.
I look at it as a way to return a lost dog to the rightful owner.
I do believe in only regulating "certain breeds" at all. All dogs bite. I do believe that dog owners will continue to come under pressure as there seems to be a fairly large percentage of the population who really either don't like dogs, or do see what all the fuss is about.
I do forsee more rules and regs coming down on dog owners
