Each canine was randomly designated a number at the beginning of the study for sample and analysis tracking. The sex of each dog is listed as either Female-Spayed (FS) or Male-Castrated (MC). Data pertaining to capsule and paired fecal samples include the internal transit time in hours of the capsule which tracked the time from capsule ingestion to excretion. The capsule sample weight refers to the weight of intestinal chyme (in mg) collected within the capsule. The DNA concentration in both capsule and fecal samples are recorded in ng/ml, where “OOR” refers to an Out of Range–too low (< 0.0100 ng/ul) reading on the Qubit 4 Fluorometer used to quantify the concentration. The analysis method that each capsule and paired fecal samples were designated to is described as either 16S (16S rRNA Sequencing) and antimicrobial resistance gene (AMRG) or Metabolome (untargeted HILIC Liquid Chromatography—Mass Spectrometry metabolomics). *Was seen chewing on both meatballs. ^capsule 1 was found alone in the rectum and was manually removed. #Hadn’t defecated the 2nd capsule by the 72 h mark and had 2 view abdominal radiographs taken (Fig. 1)
