Pet dealers; diseased animals; veterinary certificate. Requires a pet dealer to reimburse certain veterinary fees when a consumer returns or retains a diseased dog or cat, live or dead, that has been certified by a veterinarian as being unfit for purchase. Current law requires the pet dealer to refund the purchase price or exchange the unfit pet for a pet of equivalent value. The bill extends the return or reimbursement period from 10 to 20 days and eliminates the condition that the animal be pedigreed. The bill also requires a dealer to provide an animal history certificate when the consumer takes possession of a dog or cat and incorporates information on the refund provision into the text of the required notice document. The bill requires certain dealers to record and post certain information about the breeder of each animal.
