Pet Health Concerns:CMO-Craniomandibular Osteopathy

Craniomandibular Osteopathy (CMO) is a non-cancerous bone disorder. Believed to be hereditary, this condition mostly affects the bones in the head and can cause bilateral lesions on growing bones such as the jaw and the skull. Due to this condition, those bones tend to enlarge. Unfortunately, the direct cause of CMO is not currently known. Symptoms usually appear between four and eight months of age.

Pets will begin showing signs up swollen jaws, pain and difficulty eating, facial swelling, discomfort, muscle atrophy, and often times, will have trouble opening their mouth. This condition is most commonly seen in the Cairn Terrier, Scottish Terrier, and West Highland White Terrier dog breeds. Craniomandibular osteopathy can be diagnosed by conducting diagnostic tests such as radiographs, biopsies, and physical exams. Although there is no current cure for CMO, anti-inflammatory and pain medications are available to reduce discomfort.

To learn more about Craniomandibular Osteopathy in pets, check out our Pet Health Concerns Guide. By enrolling your pet with Trupanion pet insurance, your cat or dog’s policy will include coverage for diagnostic tests, medications, surgeries, hereditary and congenital disorders, as long as treatment for a certain condition is required after enrolling and is not pre-existing.

Has your pet ever been diagnosed with this condition? If so, we’d love to hear from you and any comments, advice, experiences, of thoughts on this  condition.

    I was told by Dr. Richard Ford at a meeting in Massachusetts that this condition is the result of vaccine administration. Many of our diseases we have to treat all manners of dysregulated immune systems inflammatory disease, cancer, autoimmune, allergies, asthma,atopy,anaphylaxins are all from the use of vaccines. Time to get the vaccines off the list of insurance covered procedures especially if they are not then going to cover by insurance the vaccine induced diseases that results from vaccine use, including the gene impact and genetic damage from vaccines!!!!!!!!!!!!
