in the cervical neck region is the most reliable method for estimating the
canine’s tracheal diameter. In most MWDs, a size 8.0–10.0 endotracheal
tube is appropriate. To avoid the risk of one-lung intubation, determine the
appropriate ET/CTT/TT length by measuring from the front or the canine
incisors to the thoracic inlet or point of shoulder.
NOTE: intubation of the MWD is most easily performed with the dog in sternal
or prone position (but can be performed in lateral), head and neck extended,
and tongue pulled forward. Capnometer reading >10mmHg also verifies correct
placement.
ii. If necessary assisted ventilation via an Ambu-bag can be performed at a rate of
8–10 breaths per minute.

Figure 1. Measure how far to advance
the endotracheal tube.
Hold the tracheal tube to the side of the dog
and measure from the front of the canine
incisors to the thoracic inlet or point of the
shoulder.
Mark the tube with tape. SECTION 4
