Table 5.
Presented is a summary of 2 studies evaluating quantitative parameters obtained during videofluoroscopic assessment of swallowing of kibble boluses in healthy dogs.

Bonadio et al. (17) compared results when dogs were positioned in right lateral vs. standing body position. Harris et al. (19) compared results obtained from dogs of differing ages [juvenile (0.1 ± 0.6 years), adult (4.9 ± 0.93 years), geriatric (11.3 ± 3.55 years)]. One-way ANOVA was performed to evaluate for statistically significantly different results across studies. A Tukey HSD (Honesty Significant Difference) post-hoc evaluation was also performed to determine which specific data were significantly different from one another. P ≤ 0.05 was considered significant. (@#%denotes significant differences between values in different columns but in the same row).
NA, not assessed; UES, upper esophageal sphincter; s, seconds; Max, maximum; PCR, pharyngeal constriction ratio; ISI, inter-swallow interval.
