Alpha-diversity measures of fecal samples collected from obese dogs during weight loss. (a) Alpha-diversity measures by dietary group throughout the study. (b) Alpha-diversity measures by time point throughout the study. (c) Observed OTU by dietary group in each time-point throughout the study. (d) Faith’s phylogenetic diversity (PD) by dietary group in each time point throughout the study. At baseline (week 0), all animals were fed the same diet (Original diet). Alpha-diversity, represented by observed OTU and Faith’s PD, suggested that species richness was higher in dogs fed the Original diet than those fed the Fit & Trim diet. Additionally, caloric restriction and weight loss increased species richness.
