Background

The Forever Dog Project, a community-driven initiative focused on longevity and health in Bulldog breeds, analyzed owner-reported primary diet choices in a large cohort of French Bulldogs across the United States. This study examined associations between diet type (primarily kibble/extruded, canned, commercial raw, homemade raw, or home-cooked) and various owner- and dog-related demographic variables to identify patterns and potential confounders for future nutrition research in this popular brachycephalic breed.

Key Findings

The majority of French Bulldogs (>80%) were fed a primary kibble diet, consistent with general companion dog trends but notably higher than in some regions with greater alternative diet adoption.

• Owner-Related Factors: Older owners were significantly more likely to feed diets other than kibble. This may reflect increased time availability for food preparation in later life stages or a response to age-related health changes in long-owned dogs. Owner income and education level showed no strong association with diet choice, though selection bias toward engaged, higher-education owners is acknowledged.

• Dog Size and Breed Context: As a small-to-medium breed (typically 9–13 kg), French Bulldogs were more likely to receive non-kibble diets compared to larger breeds. Higher moisture canned or cooked diets were selected more frequently, potentially due to breed predispositions to dental/oral issues, brachycephalic-related swallowing difficulties, or perceived palatability benefits. Economic barriers appeared less influential given the smaller daily feeding volumes.

• Raw Diet Patterns: Purebred status (nearly universal in this cohort), intact reproductive status, and high activity levels (e.g., agility or show dogs) were strongly associated with raw feeding. Commercial raw diets predominated in urban households, while homemade raw diets were more common in rural settings and multi-dog homes. Dogs in excellent health were more likely to receive homemade raw diets. French Bulldogs primarily used for breeding or performance purposes showed elevated raw feeding rates, aligning with broader breeder trends.

• Health Status: Poorer overall health condition correlated with higher likelihood of non-kibble diets. Owners may switch to more palatable or specialized options (e.g., home-cooked) for dogs with chronic conditions such as skin allergies, respiratory compromise affecting eating, or gastrointestinal sensitivity—common multimorbidities in the breed.

• Geographic Variation: Significant regional differences emerged, with higher non-kibble adoption in coastal urban areas (e.g., California) versus lower rates in rural Midwestern states. This highlights limited generalizability of nutrition studies conducted in single regions.

Discussion

French Bulldogs’ conformational challenges (brachycephaly, dental crowding, skin folds) may drive owners toward moist or softer diets perceived as easier to eat or beneficial for hydration and oral health. Raw feeding in performance/breeding lines raises zoonotic concerns, particularly relevant for therapy or service French Bulldogs interacting with vulnerable populations. Veterinary guidance on pathogen risks remains critical.The cross-sectional design and self-selected participant pool limit causality inferences and representativeness. Motivations behind diet choices were not directly surveyed, and emerging commercial fresh/frozen options were not captured in early data collection.

Implications

These findings underscore that dog size, age, health status, reproductive status, activity level, purpose, and geographic location act as confounders in nutrition studies. Future analyses comparing health outcomes across diet types in French Bulldogs must adjust for these variables to avoid bias. A proposed causal model positions owner beliefs and behaviors as primary drivers, mediated by measurable demographics (e.g., neuter status, breed purpose, owner age).

Conclusion

This analysis provides the first large-scale insight into diet choice patterns specific to French Bulldogs, informing targeted veterinary counseling and guiding rigorous design of breed-focused nutrition research. Understanding these demographic influences will support evidence-based recommendations to optimize healthspan in this rapidly growing breed.

The "Forever Dog Project" is a dedicated community science initiative focused on studying aging in Bulldog breeds, including French Bulldogs, English Bulldogs, and related mixes such as the Frenchie Doodle. Launched in 2022, it explores how genes, lifestyle, nutrition, and environment influence healthy aging and longevity in these beloved brachycephalic companions with the goal of improving healthspan and translating insights to better care for Bulldogs everywhere.
