Regarding Point of Origin

Shops must post where the puppies came from and provide the following information... Any violations are subject to a $1000 fine! So how are the pet shops supposed to make any money selling puppies with all of these new rules? They can't! So they voluntarily stopped selling puppies! California must have been a big loss to the puppy mill industry... I'm sure they funnel the pups in another way to sell as "home bred" dogs but what a great way to make a big dent in their projected sales by eliminating their ability to sell in pet shops!

(b) For dogs:
(1) The breeder's name and address, if known, or if not known, the
source of the dog. If the person from whom the dog was obtained is
a dealer licensed by the United States Department of Agriculture, the
person's name, address, and federal dealer identification number.
(2) The date of the dog's birth, and the date the dealer received
the dog. If the dog is not advertised or sold as purebred,
registered, or registerable, the date of birth may be approximated if
not known by the seller.
(3) The breed, sex, color, and identifying marks at the time of
sale, if any. If the dog is from a United States Department of
Agriculture licensed source, the individual identifying tag, tattoo,
or collar number for that animal. If the breed is unknown or mixed,
the record shall so indicate.
(4) If the dog is being sold as being capable of registration, the
names and registration numbers of the sire and dam, and the litter
