Excerpt from the Virginia Code:
§ 3.2-6510. Sale of unweaned or certain immature animals prohibited, vaccinations required for dogs and cats; penalty.
A. No person shall sell, raffle, give away, or offer for sale as pets or novelties, or offer or give as a prize, premium, or advertising device any living chicks, ducklings, or other fowl under two months old in quantities of less than six or any unweaned mammalian companion animal or any dog or cat under the age of seven weeks without its dam or queen. Dealers may offer immature fowl, unweaned mammalian companion animals, dogs or cats under the age of seven weeks for sale as pets or novelties with the requirement that prospective owners take possession of the animals only after fowl have reached two months of age, mammalian companion animals have been weaned, and dogs and cats are at least seven weeks of age. Nothing in this section shall prohibit the sale, gift, or transfer of an unweaned animal: (i) as food for other animals; (ii) with the lactating dam or queen or a lactating surrogate dam or queen that has accepted the animal; (iii) due to a concern for the health or safety of the unweaned animal; or (iv) to animal control, an animal shelter, or a veterinarian.
B. Dealers shall provide all dogs and cats with current vaccinations against contagious and infectious diseases, as recommended in writing and considered appropriate for the animal’s age and breed by a licensed veterinarian, or pursuant to written recommendations provided by the manufacturer of such vaccines at least five days before any new owner takes possession of the animal. For dogs, the vaccinations required by this subsection shall include at a minimum canine distemper, adenovirus type II parainfluenza, and parvovirus. For cats, the vaccinations required by this subsection shall include at a minimum rhinotracheitis, calicivirus, and panleukopenia. Dealers shall provide the new owner with the dog’s or cat’s immunization history.
C. A violation of this section is a Class 3 misdemeanor.
