Throughout the Golden Retriever Lifetime Study (GRLS) implementation, Morris Animal
Foundation (MAF) has observed high rates of compliance (μ = 81.3%) and retention (μ = 86%) across
more than 3,000 participating dog owners (Labadie et al., 2022). These rates are considerably higher than
most longitudinal clinical trials focused on humans in which the average retention rate is 73.5% (Teague
et al., 2018). Therefore, GRLS offers an opportunity to better understand factors that might affect study
compliance and retention within longitudinal and clinical veterinary and human medical studies.
