“…In the present study, when dog age was adjusted for size (body weight), dogs that had attained a higher percentage of their projected weight-based mean life span had slower speeds in the mobility trials. A previous study 21 in dogs found that owner-assessed mobility (including walking, running, and climbing stairs) decreased with increasing age quartile; although dogs with orthopedic and neurologic disease may have been overrepresented in the higher age quartiles, it is interesting that the direction of the association with age quartiles was consistent with that for quartile of projected life span attained in the present study.…”

“…In that study, 20 gait was only recorded as normal or abnormal (ie, marked stiffness, lameness, or ataxia), which is a narrower definition than that used for evaluating mobility with human frailty scales, and gait speed was not measured. In another study, 21 dog owners who completed a questionnaire to assess their dog's mobility identified decreased mobility in older dogs and in dogs with diagnosed orthopedic or neurologic disease, although this was a qualitative assessment that relied on owner-reported observations at a single time point.…”

OBJECTIVE-To develop a low-technology system that can be used by dog owners to obtain morphological and mobility measurements in companion dogs as candidate components of an eventual canine frailty scale. ANIMALS-57 adult (≥ 1-year-old) dogs enrolled by 43 owners. PROCEDURES-Morphological measurements of dogs were performed by investigators and dog owners. Dogs participated in timed in-clinic mobility trials across a flat surface (on-leash trial with the owner, on-leash trial with the investigator, and off-leash trial) and on stairs; each trial was repeated 3 times. Owners were asked to conduct a second stair trial at home 2 weeks later. Agreement between owner-and investigator-obtained measurements was assessed with Shrout-Fleiss intraclass correlation coefficients and paired t tests. Age, quartile of projected percentage of mean life span attained (adjusted for body weight), and height were evaluated as predictors of speed and stride length in mobility trials with linear regression and Spearman rank correlation analysis. RESULTS-Agreement between owner-and investigator-obtained morphological measurements was strong. Age was a weak but significant predictor of decreased dog speed in mobility trials (adjusted R 2 , 0.10 to 0.23). Speed decreased significantly with increasing quartile of projected life span attained. A linear regression model that included height and age predicted dog speed better than models with age or height alone.

As the most phenotypically diverse mammalian species that shares human environments and access to sophisticated healthcare, domestic dogs have unique potential to inform our understanding of the determinants of aging. Here we outline key concepts in the study of aging and illustrate the value of research with dogs, which can improve dog health and support translational discoveries. We consider similarities and differences in aging and age-related diseases in dogs and humans and summarize key advances in our understanding of genetic and environmental risk factors for morbidity and mortality in dogs. We address health outcomes ranging from cancer to cognitive function and highlight emerging research opportunities from large-scale cohort studies in companion dogs. We conclude that studying aging in dogs could overcome many limitations of laboratory models, most notably, the ability to assess how aging-associated pathways influence aging in real-world environments similar to those experienced by humans. Expected final online publication date for the Annual Review of Animal Biosciences, Volume 10 is February 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Over the last few decades, frailty has become a pillar of research and clinical assessment in human gerontology. This complex syndrome, characterized by loss of physiologic reserves leading to decreased resilience to stressors, is of critical importance because it predicts higher risks of poor health outcomes, including mortality. Thus, identifying frailty among the elderly human population has become a key focus of gerontology. This narrative review presents current scientific literature on frailty in both humans and animals. The authors discuss the need for an accessible frailty instrument for companion dogs suitable for general use in veterinary medicine and the advances that would be facilitated by this instrument. A phenotypic frailty instrument for companion dogs, utilizing components that are easily collected by owners, or in the general practice setting, is proposed. The authors elaborate on the domains (physical condition, physical activity, mobility, strength, cognitive task performance, and social behavior), factors that will be included, and the data from the Dog Aging Project that inform each domain.

Development of a scale to evaluate mobility in dogs

Abstract: The purpose of this study was to develop and to assess the psychometric characteristics of a mobility scale for dogs. The original ten questions were reduced using validation process. One hundred and twenty three dog owners were invited
