Fecal microbial communities of dogs fed extruded, mildly cooked, and raw diets. (A) Alpha diversity measures suggested that species richness was lower (P < 0.05) in dogs fed the high-moisture grain-free roasted refrigerated (GFRR) diet or raw (RAW) diet than dogs fed the extruded dry kibble (EXT) diet. Principal coordinates analysis plots of unweighted (B) UniFrac distances of fecal microbial communities performed on the 97% OTU abundance matrix tended to reveal a separation (P = 0.07) between dogs fed GFRR or RAW from dogs fed EXT. Principal coordinates analysis plots of weighted (C) UniFrac distances of fecal microbial communities performed on the 97% OTU abundance matrix tended to reveal a separation (P = 0.07) between dogs fed the high-moisture roasted refrigerated (RR) diet or RAW from dogs fed EXT. Each dot represents a sample collected from each dog (n = 8/treatment). OTU = operational taxonomic units.
