Predicting dog tracheal diameter and length: A tool for improved intubation.

Objective: This study aims to develop formulas for estimating tracheal diameter and length in dogs using easily measurable anatomical parameters.

Materials And Methods: The samples consisted of 20 dogs of various breeds, comprising 10 males and 10 females, sourced from cadavers. The measured parameters included occipital tuberosity to tail base (OT), eye angle to ear tragus, nose to ear tragus, inner vertical diameters (IVD), and tracheal length (TL).
