Fig 5. Responses of dogs to DB at concentrations of 10μM and 100μM vs water.

Fig 5

Data are shown as intake difference in g/kg bodyweight. Data points show each individual exposure event. A) Ten miniature schnauzers were exposed to 10μM DB and water on two consecutive days, showing no significant difference in preference (mean = 0.866, 95%CI = -13.656 to 11.923, p = 0.883). B) 76 dogs of three different breeds were exposed to 100μM DB on two consecutive days, showing a significant mean preference for water over DB, (mean = -16.949, 95%CI = -21.931 to -12.590, p <0.001). When data from the three breeds are analysed independently, cocker spaniels (mean = -34.132, 95%CI = -54.020 and -14.244, p <0.001), Labrador retrievers (mean = -12.955, 95%CI = -20.872 and -5.039, p <0.001), and miniature schnauzers (mean = -13.828, 95%CI = -20.939 and -6.717, p <0.001) all demonstrated a significant mean preference for water over DB. The Tukey post-hoc multiple comparison test was used to produce p-values.
