Discussion: Craniomandibular osteopathy is a non-neoplastic, proliferative  bone disease that affects primarily the mandible, tympanic bullae, frontal bone and occasionally long bones in dogs of about three to eight months.

The proliferation of new bone of the head and jaws decreases as the endochondral ossification of the long bones slows after 7 to 8 months of age.
