Principal components analysis (PCA) for serum metabolomics data of dogs fed dry food (DF) and softened dry food (SDF) on day 21 (A). Orthogonal Partial Least-Squares-Discriminant Analysis (orthoPLS-DA) for serum metabolomics data of dogs fed dry food (DF) and softened dry food (SDF) on day 21 (B). Enrichment bar plot based on the serum differential metabolites of dogs fed dry food (DF) and softened dry food (SDF) on day 21 (C). Bar plot based on the serum differential metabolites which were enriched in the differential metabolite pathways between two groups (D). The symbol (**) indicates the difference between the dry food (DF) and softened dry food (SDF) groups.
