A Beta diversity profile (weighted Unifrac distance) of gut microbiota among healthy and diseased dogs at baseline, and weeks 2 and 8. B Time course comparison of the diseased group's microbiota measured by distance (weighted Unifrac) to the healthy group. C Violin plots demonstrate microbial composition among groups or time points along axis 2 (Kruskal–Wallis test among groups, p = 0.01). The significance of pairwise tests by Dunn's test is labelled as *p < 0.05, **p < 0.01
