Craniomandibular Osteopathy in a Newfoundland Dog

A 5-month-old Newfoundland dog was presented with lethargy and bilateral enlargement of the mandibles and maxillae. A diagnosis of craniomandibular osteopathy was made based on clinical signs, physical examination, and computed tomography findings. Improved mentation and comfort levels were achieved with pain management using meloxicam and paracetamol. Follow-up examinations were performed at 1, 2, 6, and 16 weeks after the first consultation. Stabilization of the condition was noted initially, and by 16 weeks, clinical symptoms had markedly improved. Protuberances of the maxillae were markedly reduced compared to the initial presentation, and the maxillae appeared nearly normal. Widening of the mandibles had decreased, and the bony swelling extended less caudally. To the authors' knowledge, this is the first report of craniomandibular osteopathy in a Newfoundland dog.
