In the United States, there are 78 million dogs and 85.8 million cats (ASPCA, n.d.). According to ASPCA, more than 6.5 million companion animals are housed in animal shelters across the country (ASPCA, n.d.). This comprises 3.3 million and 3.2 million dogs and cats respectively (ASPCA, n.d.).Also, due to the increasing number of animals whose owners cannot be traced, about 670,000 dogs and 860,000 dogs are euthanized every year (ASPCA, n.d.).
The solution to the thousands of animals that are lost or euthanized can be found in a biometric system that can allow animal handlers to locate the owners. Also, due to the mobility of animals, the system must be linked to a national database that would make it possible to identify lost pets in any part of the country. The information captured in the biometric system would include the physical description of the pet including the color, size, and species.
