Establish your dog's gut microbiome baseline with Best Friend Bioscience's 2-Sample Gut Baseline Test Kit and Report. Collect two 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, so sampling across two months helps confirm your dog's core gut profile and measure its natural stability. Your combined report tracks microbial balance, diversity, and digestive health across both 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.
