Distribution graphs of gut microbiota composition at phylum, family and genus level in lean and overweight dogs. Gut microbial taxa of phylum (A), family (B) and genus level (C) present in over 50% of the observations are shown in relative abundance (proportions) with the three sampling time points (days 1, 5 and 10) pooled to mean relative abundance for each dog. Microbial phyla, families and genera with low relative abundance (mean < 1%) are grouped as “phyla, families or genera of low abundance” and non-identified taxa are grouped as “others”. Dogs were divided into two body condition groups; lean (BCS 4–5, n = 12) and overweight (BCS 6–8, n = 15). Individual dog ID numbers are shown on the x-axis and dogs are listed according to increasing body condition score (BCS 4–8, left to right). All phyla, families and genera, including those of low abundance, are listed in the raw data in Additional file 2
