Craniomandibular Osteopathy in a Newfoundland Dog

Area of Science:

• Veterinary Medicine
• Canine Pathology
• Skeletal Biology

Background:

• Craniomandibular osteopathy (CMO) is a non-arthritic, developmental bone disease.
• It primarily affects young dogs of certain breeds, causing progressive enlargement of the mandible and maxilla.
• This condition can lead to significant pain, dysfunction, and cosmetic changes.

Purpose of the Study:

• To report the first case of craniomandibular osteopathy in a Newfoundland dog.
• To describe the clinical presentation, diagnostic findings, and treatment outcome.
• To highlight the breed's potential susceptibility and the disease's progression and management.

Main Methods:

• Clinical assessment of a 5-month-old Newfoundland dog with lethargy and facial swelling.
• Diagnostic imaging, including computed tomography (CT), to evaluate mandibular and maxillary structures.
• Pharmacological pain management utilizing meloxicam and paracetamol.
• Serial follow-up examinations over 16 weeks to monitor disease progression and treatment efficacy.

Main Results:

• Diagnosis of craniomandibular osteopathy confirmed via clinical signs and CT.
• Significant improvement in mentation and comfort following pain management.
• Radiographic evidence of reduced maxillary protuberances and decreased mandibular widening by week 16.
• Overall stabilization and marked improvement of clinical symptoms over the 16-week observation period.

Conclusions:

• Craniomandibular osteopathy can occur in Newfoundland dogs, representing a novel breed association.
• Pain management with meloxicam and paracetamol is effective in alleviating clinical signs.
• Early diagnosis and supportive care can lead to favorable outcomes and significant improvement in affected dogs.
