Table of State Laws Concerning Minimum Age for Sale of Puppies

“How old must a puppy be prior to being offered for sale?”

The answer to this question, like just about any question in law, depends on where you live. Approximately twenty states have laws or administrative regulations that state how old a puppy must be before it is offered for sale or adopted out to an owner. Of those states with laws, all but three require that a puppy be at least eight weeks old before being offered for sale. Maine, Virginia, and Wisconsin mandate that a puppy be at least seven weeks old. Other states focus on the separation of the puppy or kitten from its mother in addition to specifying a minimum age. Nevada's law provides that a retailer, dealer, or operator shall not separate a dog or cat from its mother until it is 8 weeks of age "or accustomed to taking food or nourishment other than by nursing., whichever is later." [emphasis added]. Likewise, Illinois also phrases such that a puppy or kitten shall not be "separated from its mother" until the puppy or kitten has attained the age of 8 weeks.

One thing crucial to understand with these puppy sale laws is that they may not apply to everyone. In other words, the laws may be limited to a particular class of people, such as dog breeders, kennel operators, or other animal facilities.About twelve of the eighteen states make it unlawful for any person to sell an underage puppy. The remaining states limit the provisions to pet shops, animal dealers, or breeders. Like many of the pet sale laws (generally known as “puppy lemon laws”), the focus of these laws is on curbing the distribution of puppies from unregulated sources like puppy mills rather than preventing sales by those not in the breeding business (i.e., individuals who are simply giving away an unwanted litter).

Since the goal of most of these laws is to curb the business of selling underage dogs, protecting both the dogs and consumers, certain parties are excluded from these laws. As may be expected, many states exclude non-profit animal shelters or humane societies from the law’s reach. This type of exclusion becomes necessary when considering the unwanted puppies often left on the doorstep of such organizations. In addition, a few states have provisions that exclude those dealers regulated by the United States Department of Agriculture (USDA) under the Animal Welfare Act (AWA) who supply dogs for research purposes. The federal AWA regulates only a specific group of people involved in dog commerce; specifically, dog dealers and exhibitors. Dealers are defined as those individuals who buy dogs to sell for research or pets, but that term does not include retail pet stores. Exhibitors are those individuals who purchase animals to exhibit or perform in circuses, zoos, carnivals, and the like. With those limitations in mind, the AWA regulations (the rules by which the dealers and research institutions must abide to maintain their licenses and avoid fines) state that no dog may be delivered to any transportation carrier unless it is at least eight weeks old and weaned. This provision (Sec. 2.130) excludes registered research facilities, however.

Certain parties may be excluded by default because the statute does not reach the activity. For example, many of the state statutes only apply to sales of puppies and not any transfers that do not involve any monetary exchange or other consideration. In fact, the impetus behind nearly all of these statutes is to regulate the commerce in puppies within the state. However, Colorado, Connecticut, Maine, Massachusetts, and Pennsylvania include adoption or any transfer of an underage puppy within their laws. 

The penalties for violation of these provisions are typically lenient. About half the states make a violation of the law a criminal misdemeanor. California’s law makes it a misdemeanor to sell a puppy under the age of eight weeks as does Nebraska's. Violation of Connecticut's law can now result in $500 fine and/or even 30 days in jail. Most state penalties, if even specified, range from a fine of $50 to a possible $1,000. Many of the statutes make the action unlawful, but fail to describe what would happen to a person who violates the section.

What happens in those states without such laws? This answer is less than clear. Certainly a retailer who sells a puppy not yet weaned from his or her mother and able to eat on his or her own may not be acting in the best interests of the puppy. Should the puppy then suffer or die because of a retailer's intentional or reckless conduct, the retailer could conceivably face animal cruelty charges. Moreover, in those states that have enacted pet purchaser protection laws, a possible claim against that merchant for violation of an implied warranty could be raised by a purchaser of an underage dog. Even in those states with laws, the best action by a purchaser is to research the breed he or she wishes to purchase or talk to a veterinarian in advance to find the best age to adopt a new puppy.
