'''Narrow Mandible''': In some animals, the mandible is too narrow with respect to the upper jaw. The result is that the lower canines impinge on the maxillary [[Gingiva|gingivae]] or the [[Hard Palate|hard palate]] instead of fitting into the diastema between the upper third incisor and upper canine on either side. The animal may not be able to close its mouth and injury to the gingivae or palatal mucosa commonly occurs. In severe, untreated cases an oronasal communication may develop over time. This condition is seen in both the primary (deciduous) and permanent dentition. Persistent mandibular primary canines will further exacerbate the condition, as the permanent mandibular canines erupt medially to their primary counterparts. The incorrect dental interlock will interfere with the normal growth in width and length of the developing mandible. The condition can also be caused by persistent primary mandibular canines in a mandible of normal width. <font color="red">(pic 7 malocclusion)</font color>

'''Malocclusion of the Canine Teeth''': The two most common abnormalities in canine tooth position are:
* Rostral displacement (mesioversion) of the maxillary canines (also known as '''lance canines'''). Persistent primary canines may be responsible for this condition. A breed predisposition has been reported in the Shetland sheepdog. <font color="red">(pic9malocclusion)</font color>
