For purposes of this section and notwithstanding the provisions of section 273.325, the following terms have the following meanings:  (1) "Adequate rest between breeding cycles" means, at minimum, ensuring that female dogs are not bred to produce more litters in any given period than what is recommended by a licensed veterinarian as appropriate for the species, age, and health of the dog;  (2) "Covered dog" means any individual of the species of the domestic dog, Canis lupus familiaris, or resultant hybrids, that is over the age of six months and has intact sexual organs;  (3) "Necessary veterinary care" means, at minimum, examination at least once yearly by a licensed veterinarian, prompt treatment of any serious illness or injury by a licensed veterinarian, and where needed, humane euthanasia by a licensed veterinarian using lawful techniques deemed acceptable by the American Veterinary Medical Association;  (4) "Person" means any individual, firm, partnership, joint venture, association, limited liability company, corporation, estate, trust, receiver, or syndicate;  (5) "Pet" means any species of the domestic dog, Canis lupus familiaris, or resultant hybrids, normally maintained in or near the household of the owner thereof;  (6) "Regular exercise" means the type and amount of exercise sufficient to comply with an exercise plan that has been approved by a licensed veterinarian, developed in accordance with regulations regarding exercise promulgated by the Missouri department of agriculture, and where such plan affords the dog maximum opportunity for outdoor exercise as weather permits;  (7) "Retail pet store" means a person or retail establishment open to the public where dogs are bought, sold, exchanged, or offered for retail sale directly to the public to be kept as pets, but that does not engage in any breeding of dogs for the purpose of selling any offspring for use as a pet;  (8) "Sufficient food and clean water" means access to appropriate nutritious food at least twice a day sufficient to maintain good health, and continuous access to potable water that is not frozen and is generally free of debris, feces, algae, and other contaminants;  (9) "Sufficient housing, including protection from the elements" means the continuous provision of a sanitary facility, the provision of a solid surface on which to lie in a recumbent position, protection from the extremes of weather conditions, proper ventilation, and appropriate space depending on the species of animal as required by regulations of the Missouri department of agriculture and in compliance with the provisions of subsection 7 of this section.

Any person subject to the provisions of this section shall maintain all veterinary records and sales records for the most recent previous two years. These records shall be made available to the state veterinarian, a state or local animal welfare official, or a law enforcement agent upon request.  6. The provisions of this section are in addition to, and not in lieu of, any other state and federal laws protecting animal welfare. This section shall not be construed to limit any state law or regulation protecting the welfare of animals, nor shall anything in this section prevent a local governing body from adopting and enforcing its own animal welfare laws and regulations in addition to this section. This section shall not be construed to place any numerical limits on the number of dogs a person may own or control when such dogs are not used for breeding those animals and selling any offspring for use as a pet. This section shall not apply to a dog during examination, testing, operation, recuperation, or other individual treatment for veterinary purposes, during lawful scientific research, during transportation, during cleaning of a dog's enclosure, during supervised outdoor exercise, or during any emergency that places a dog's life in imminent danger. Nothing in this section shall be construed to limit hunting or the ability to breed, raise, sell, control, train, or possess dogs with the intention to use such dogs for hunting or other sporting purposes.  7.

If any provision of this section, or the application thereof to any person or circumstances, is held invalid or unconstitutional, that invalidity or unconstitutionality shall not affect other provisions or applications of this section that can be given effect without the invalid or unconstitutional provision or application, and to this end the provisions of this section are severable. ­­-------- (L. 2010 Adopted by Initiative, Proposition B, November 2, 2010, A.L. 2011 S.B. 113 & 95, A.L. 2011 S.B. 161)  Effective 4-27-11
