- Mean relative percentages (mean rel. freq) and standard deviation (SD) of the most abundant bacterial groups, annotated to the level of phylum, family and genus, based on sequencing of the V1-V3 region of the 16S rRNA gene
- 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
- A,B: Operational taxonomic units not sharing a common letter between breed groups differ significantly. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001; NS not significant
