Every year, between 6 and 8 million dogs and cats enter US animal shelters.[103] The Humane Society of the United States (HSUS) estimates that approximately 3 to 4 million of those dogs and cats are euthanized yearly in the United States.[104] However, the percentage of dogs in US animal shelters that are eventually adopted and removed from the shelters by their new owners has increased since the mid 1990s from around 25% to a 2012 average of 40% among reporting shelters[105] (and many shelters reporting 60Ц75%). An animal shelter is a facility that houses homeless, lost, or abandoned animals; primarily a large variety of dogs and cats. In the past, such a shelter was more commonly referred to as a dog pound, a term which had its origins in the impoundments of agricultural communities, where stray cattle would be penned up or impounded until claimed by their owners. The ideal goal of the modern animal shelter is to provide a safe and caring environment until the animal is either reclaimed by its owner, placed in a new home, or placed with another organization for adoption.[citation needed] Many shelters temperament test animals before they are put up for adoption to determine if the animal is adoptable and, if so, what the appropriate home environment would be. However, in the United States, many government run animal shelters operate in conditions that are far from the ideal. In the wake of the financial crisis of 2007Ц2010 many government shelters have run out of adequate space and financial resources. Currently, 64% of all incoming animals left at a government run shelter are euthanized.[1] Owners who choose to drop a pet off at one of these shelters are only giving that pet a 36% chance of survival. Shelters unable to raise additional funds to provide for the increased number of incoming animals have no choice but to euthanize them, sometimes within days.[2] The statistics are less grim at no-kill shelters.[1] Some public animal shelters around the world also euthanize animals that are not adopted within a set period of time (usually 7 to 14 days); others, however, limit that policy to only putting down animals that are in distress due to age or illness. Most private shelters are typically run as no-kill shelters. United States In the United States there is no government run organization that provides oversight or regulation of the various shelters on a national basis. However, many individual states do regulate shelters within their jurisdiction. One of the earliest comprehensive measures was the Georgia Animal Protection Act of 1986. The law was e acted in response to the inhumane treatment of companion animals by a pet store chain in Atlanta.[3] The Act provided for the licensing and regulation of pet shops, stables, kennels, and animal shelters, and established, for the first time, minimum standards of care. The Georgia Department of Agriculture was tasked with licensing animal shelters and enforcing the new law, through the Department's newly created Animal Protection Division. An additional provision, added in 1990, was the Humane Euthanasia Act, which was the first state law to mandate intravenous injection of sodium pentothal in place of gas chambers and other less humane methods.[4][5] The law was further expanded and strengthened with the Animal Protection Act of 2000.[6] Currently it is estimated that there are approximately 5,000 independently run animal shelters operating nationwide.[7] Shelters have redefined their role since the 1990's. No longer serving as an until-death repository for strays and drop-offs, modern shelters have taken the lead in controlling the pet population, promoting pet adoption, and studying shelter animals health and behavior. Shelters, and shelter-like volunteer organizations, responded to cat overpopulation with trap-neuter-release programs that reduce feral cat populations and reduce the burden on shelters. [edit]Canada In Canada, the government-run Humane Society shelters specialize in dogs, cats, and small rodents. Some shelters will also keep reptiles and/or parrots. [edit]United Kingdom In the United Kingdom, animal shelters are more commonly known as rescue or rehoming centers, and are run by charitable organizations. The most common rescue and rehoming organizations are the RSPCA, Cats Protection, and the Dogs Trust. [edit]Germany Most larger cities in Germany either have a city shelter for animals or contract with one of the very common non-profit animal organizations throughout the country, which run their own shelters. Most shelters are populated by dogs, cats and a variety of small animals like mice, rats and rabbits. Additionally there are so-called Gnadenhofe for larger animals. They take cattle or horses from private owners who want to put them down for financial reasons. Under German law the euthanization of animals is restricted to medical reasons or cases where the animal is dangerous, not controllable and actually poses a danger to humans (Gefahr im Verzug - exigent circumstance). Most dangerous animals, such as aggressive dogs (possession of some special breeds is restricted), are locked away until rehoused to an controlled environment.
