California Code, Health and Safety Code - HSC § 122310

(a) For every dog sold by a dog dealer or dog breeder that is sold with any representation that the dog is registered or registerable with a dog pedigree registry, the following fully completed disclosure shall be made, orally and in writing on a separate sheet from any other statements, including, but not limited to, the name of the dog dealer or breeder and the name of the relevant dog pedigree registry:

“Disclosure by

Registration means only that __________ [enter name of registry] maintains information regarding the parentage and identity of this dog, it does not guarantee the quality or health of this dog, and it does not guarantee quality lineage. Since dog pedigree registries depend in large part on the honesty and accuracy of persons registering dogs, registration does not guarantee the accuracy of the lineage recorded nor that this dog is purebred.

(b) The disclosure in subdivision (a) shall be signed and dated by the retail purchaser of the dog acknowledging receipt of a copy of the statement and the dog dealer or dog breeder shall retain a copy.
