Table 4 Prevalence of the combined list from the 10 most common disorders recorded at a fine-level of diagnostic precision within each of three age bands (under 2 years, 2–7 years, over 7 years) in Chihuahuas under primary veterinary care at UK practices participating in the VetCompass™ Programme from January 1st to December 31st, 2016. The P-value reflects prevalence comparison between the three age bands using the statistical test described. Under 2 years N = 1918, 2–7 years N = 2988, over 7 years N = 664). *CI confidence interval
