Any form of tying, chaining or tethering is prohibited unless the dog is in visual range of the responsible party, and the responsible party is located outside with the dog. Violation of this regulation may result in impoundment of your dog and a maximum civil fine of $1,000.
According to the Humane Society of the United States, chaining and tethering is both inhumane and a threat to the safety of the confined dog, other animals and humans.
“Dogs are naturally social beings who thrive on interaction with human beings and other animals. A dog kept chained in one spot for hours, days, months or even years suffers immense psychological damage. An otherwise friendly and docile dog, when kept continuously chained, becomes neurotic, unhappy, anxious and often aggressive,” according to the HSUS. “In many cases, the necks of chained dogs become raw and covered with sores, the result of improperly fitted collars and the dogs' constant yanking and straining to escape confinement. Dogs have even been found with collars embedded in their necks, the result of years of neglect at the end of a chain.”
In addition to The Humane Society of the United States and numerous animal experts, the U. S. Department of Agriculture issued a statement in the July 2, 1996, Federal Register against tethering:
"Our experience in enforcing the Animal Welfare Act has led us to conclude that continuous confinement of dogs by a tether is inhumane. A tether significantly restricts a dog's movement. A tether can also become tangled around or hooked on the dog's shelter structure or other objects, further restricting the dog's movement and potentially causing injury."
According to the HSUS, Dogs tethered for long periods can become highly aggressive. Dogs feel naturally protective of their territory; when confronted with a perceived threat, they respond according to their fight-or-flight instinct. A chained dog, unable to take flight, often feels forced to fight, attacking any unfamiliar animal or person who unwittingly wanders into his or her territory.
Numerous attacks on people by tethered dogs have been documented. Tragically, the victims of such attacks are often children who are unaware of the chained dog's presence until it is too late. Furthermore, a tethered dog who finally does get loose from his chains may remain aggressive, and is likely to chase and attack unsuspecting passersby and pets.
In addition to the psychological damage wrought by continuous chaining, dogs forced to live on a chain make easy targets for other animals, humans, and biting insects. A chained animal may suffer harassment and teasing from insensitive humans, stinging bites from insects, and, in the worst cases, attacks by other animals. Chained dogs are also easy targets for thieves looking to steal animals for sale to research institutions or to be used as training fodder for organized animal fights.
According to the HSUS, “Rarely does a chained or tethered dog receive sufficient care. Tethered dogs suffer from sporadic feedings, overturned water bowls, inadequate veterinary care, and extreme temperatures. During snow storms, these dogs often have no access to shelter. During periods of extreme heat, they may not receive adequate water or protection from the sun. What's more, because their often neurotic behavior makes them difficult to approach, chained dogs are rarely given even minimal affection. Tethered dogs may become "part of the scenery" and can be easily ignored by their owners.”
The HSUS recommends that all dogs live indoors as a part of the family, are taken on regular walks, and otherwise provided with adequate attention, food, water and veterinary care. If an animal must be housed outside at certain times, he should be placed in a suitable pen with adequate square footage and shelter from the elements.
