The =parotid gland= is small. Its upper part is wide and is divided into
two lobes by a deep notch into which the base of the ear is received.
The lower end is small and overlaps the submaxillary gland. The =duct=
leaves the gland at its anterior border, crosses the masseter muscle,
and opens into the mouth opposite the third upper cheek tooth. Small
accessory glands (Glandulæ parotidæ accessoriæ) are sometimes found
along the course of the duct.
The =submaxillary gland= is usually larger than the parotid. In large
dogs it is about two inches (ca. 5 cm.) long and an inch or more (ca. 3
cm.) wide. It is rounded in outline and of a pale yellow color. Its
upper part is covered by the parotid, but it is otherwise superficial,
and is palpable in the angle of junction of the jugular and external
maxillary veins. The =duct= leaves the deep face of the gland, passes
along the surface of the digastricus and stylo-glossus, and opens into
the mouth near the frenum linguæ on a very indistinct papilla.
