Patients may want and express benefit from animal-assisted activity dog visits, but the outcomes of the visits may not be measureable. Nurses should assess to what extent patients believe that such visits are beneficial by asking them. The visits may be valued by patients as helping to relieve their anxiety and as distractions from their disease and therapy.

Our data indicate that use of CGMS is valid for dogs, cats, and horses. This system alleviated the need for multiple blood samples and the stress associated with obtaining those samples. Because hospitalization was not required, information obtained from the CGMS provided a more accurate assessment of the animal's glucose concentrations for an extended period, compared with measurement of blood glucose concentrations. Use of the CGMS will promote the diagnostic and research potential of serial glucose monitoring.

Healthy People 2010 cited walking as a major health indicator; however, adherence is challenging, especially among those with multiple chronic illnesses. Studies suggest that walking one's own dog may motivate adherence. However, no research has studied whether walking a "loaner" dog may facilitate adherence. Using a pretest-posttest design, the authors studied adherence to and outcomes of a graduated walking program when 26 public housing residents walked certified therapy dogs with a handler. Participants walked 20 minutes, 5 days/week, for 26 or 50 weeks. In all, 13 participants in the 50-week group had a mean adherence rate of 72% and weight loss of 14.4 pounds (p = .013). Thirteen participants in the 26-week group had a mean adherence rate of 52% and weight loss of 5 pounds (nonsignificant). Participants' most commonly stated reason for adherence was that the dogs "need us to walk them." Commitment to a dog that is not one's own may effectively facilitate physical activity.

Auricular temperature readings obtained by use of an auricular thermometer in dogs with otitis externa are accurate measurements of body temperature, compared with rectal temperature measurements. Temperature measurements are reliable before and after examination of the ear canal.

Animal visitation programs have been used in a wide variety of clinical settings with predominantly positive outcomes reported anecdotally. However, there is also a growing body of research investigating the effects of these interventions. Developing and conducting rigorous studies of animal interventions can be a complex and challenging process, The purpose of this article is to identify and discuss several issues arising with this type of research and to posit suggestions for avoiding pitfalls.
