The bill keeps changing, as the California breed and training clubs raise objections, but last time I looked, it still doesn't make sense. Commercial breeders will continue to bring dogs in from out of the country, and everyone expects the rate of bringing dogs in illegally will increase. These will be the products of the worst sort of puppy mills, I imagine. Or, the big time commercial breeders and puppy millers will find a way to be sure their dogs are exceptions--either as 'service' or 'show' dogs, who have immunity (in some cases) . It won't touch the feral cat population, and cats are by and large the greatest problem for shelters in this state. And, enforcement will probably be haphazard, since it's an unfunded mandate. And on and on.
