The Humane Society of the United States (HSUS)'s estimates on pet ownership and pets adopted from or euthanized in U.S. shelters in 2012 and 2013

The U.S. has come a long way over the last few decades in increasing pet ownership and decreasing euthanasia. From 1970 to 2010, the number of dogs and cats in homes has increased from 67 million to an estimated 164 million. The annual number of dogs and cats euthanized in shelters has also decreased from 12–20 million to an estimated 3–4 million. However, there's still work to do: An estimated 2.7 million healthy shelter pets are not adopted each year, and only about 30 percent of pets in homes come from shelters and rescues.
This page's figures were compiled from the 2013–2014 APPA National Pet Owners Survey and estimated by The Humane Society of the United States using statistics provided by The National Council on Pet Population Study and Policy.
