The role of skull anatomy in sensory perception in brachycephalic dog breeds

The study aims to investigate the influence of brachycephalic skull morphology on sensory perception in selected dog breeds. Brachycephalic breeds, known for their distinct cranial structure, often exhibit unique sensory capabilities, which this study seeks to understand in relation to anatomical features. English, French Bulldogs and Pugs breeds were chosen due to their distinctive brachycephalic features and their popularity in this study. Sensory perception was assessed using a series of standardized tests targeting olfactory, visual, and auditory capabilities. These assessments were correlated with detailed cranial measurements obtained through 3D imaging and MRI scans. Statistical analysis was performed to determine the relationship between specific cranial features and sensory function. Preliminary findings suggest a significant correlation between certain aspects of brachycephalic skull morphology and altered sensory perception. Notably, reduced olfactory function was observed in breeds with more pronounced cranial shortening. Visual and auditory perceptions were also found to be affected by specific anatomical traits, with variability noted across different breeds. The study concludes that brachycephalic skull morphology plays a crucial role in shaping sensory perception in these dog breeds. The findings have implications for understanding the sensory limitations and welfare concerns associated with brachycephalic breeds, guiding future breeding and care practices.
