Build a robust gut microbiome baseline for your dog with Best Friend Bioscience's 3-Sample Gut Baseline Test Kit and Report. Collect three monthly samples during a stable, typical period with no diet changes, new foods, medications, or supplements between collections. Some variation in gut microbial composition is normal, and sampling across three months gives a more complete picture of your dog's core gut profile and its natural stability over time. Your combined report tracks microbial balance, diversity, and digestive health across all three time points, building a reliable reference for what is truly normal for your individual dog. The ideal starting point before any planned dietary shift, new medication, supplement routine, or life stage transition.
