abstract
OBJECTIVE: To describe the demographic factors of owners and their dogs associated with owner feeding choices and the regularity with which those diets were fed to a US-based population of dogs. METHODS: This cross-sectional analysis examined 40,367 initial survey responses from US dog owners participating in the Dog Aging Project. The surveys were collected from January 2, 2020, to December 31, 2022, and included primary and secondary diet component types and dog and owner demographic variables. Each demographic variable was compared across diet type choices with a 2 test of independence. RESULTS: Most owners (82%) fed a commercially prepared extruded dry diet (kibble) as the primary diet component. Most owners (89%) reported that they fed their dogs a consistent diet over time. Owner demographic factors (income, education level) were less correlated with difference in diet choices than dog demographic factors (size, neuter status, purebred status, activity level), but owner age did correlate with choice: younger owners tended to feed kibble more compared to older owners. Home-cooked diets were most often consumed by small (< 30-lb) dogs, purebred dogs in poorer health status, and dogs with owners aged 45 years or older. Raw diets were more commonly fed to purebred, intact, and highly active dogs. Ten percent of service dogs were reportedly fed a raw diet of some sort. CONCLUSIONS: Demographic variables are associated with statistically significant differences in diet types selected. Nutrition studies examining health outcomes associated with the feeding of different diet types should account for these factors during design or analysis in order to avoid bias. An epidemiological tool, the directed acyclic graph, is presented. CLINICAL RELEVANCE: This information will help clinicians in their discussions with clients about pet nutrition.
