3.3.5 General inspection of the head and neck
A thorough examination of this region is important before moving on to the thorax. If a nasal discharge is present, it is important to note whether it is unilateral or bilateral, mucoid, mucopurulent or sanguinous, foul smelling or odourless. The owners should be questioned about its duration. Palpation of lymph nodes may reveal important information. The larynx should be palpated for evidence of muscle atrophy, and examined for scars indicative of previous surgery.
