Non-metric multidimensional scaling (NMDS) ordination of nasal microbiota communities using Bray-Curtis in healthy dogs from 3 different breed groups. Significant clustering was observed between breed groups. (green, group DL; blue, group B; red, group T). Samples are represented by dots and the lines connecting dots are vectors defining the centromere of the group. Group DL = mesocephalic or dolichocephalic dogs of medium to large breeds. Group B = brachycephalic dogs of small breeds. Group T = mesocephalic or dolichocephalic terrier dogs of small breeds. Stress value = 0.1255474
