To the surprise of many animal advocates, discussions are taking place this year on whether there may be too few dogs to support demand in the US. The campaign that began in the 1970s to reduce dog over-supply has been very successful. In 1973, approximately 7 million dogs were euthanized in shelters when the pet dog population was around35 million. In 2021, 300,000 dogs were euthanized in animal shelters, but the pet dog population had grown to somewhere between 65 and 90 million, depending on which survey is consulted. Although 300,000 is still too many dogs, it represents more than a 95% reduction in the euthanasia of shelter dogs.
