The carefully controlled use of random-source dogs and cats contributes greatly to improving the health and welfare of both animals and human beings. Therefore, the AVMA believes there is ample justification for prudent and humane use of random-source dogs and cats in research, testing, and education, provided that:

• The institution conducting such research, testing, or education has met all legal requirements and guidelines pertaining to the acquisition, care, and use of dogs and cats for these purposes;
• The investigators have thoughtfully examined the need for such dogs and cats, appropriately justified the use of the species, and carefully determined the minimum number required to meet the needs of the protocol;
• Adequate safeguards are used to ensure that only appropriately screened dogs and cats are obtained legally; and
• Preventive measures are taken to optimize the health of dogs and cats used in research, testing, and education.
