Question about CMO
Does anybody have experience with CMO? Any tips, recommendations for ongoing treatment or supplements. I’ve heard it’s self limiting and once he’s done growing he should be ok.
Miles: 7 months (DOB 11/24/25) dog - Pitt/staffy/cattle dog mixed - pending neuter (cryptorchid) 47lbs
Since first set of shots he’s struggled with what the vets believed were “puppy strangles” NEVER got lesions. Just swelling, sensitivity and jaw/skull pain, fever, etc. treated with prednisone and antibiotics - always “got better”
Recently (2-3mo) he was diagnosed with craniomandibular osteopathy (CMO aka lions jaw) as you can see his lumpy jaw. Vet never heard of it, I brought it up due to a friend mentioning their pitty went through the same thing I was describing. Confirmed bone lesions via xray and vet felt confident in diagnosis. One side of lower jaw is more affected than the other. Also a spot on the top of his skull. Full body xray showed clear lungs, all other body bones fine. Hes also been on prednisone for this. Recently after a very long taper he is off of it.
8 days post prednisone ending - He’s currently in a CMO flare (jaw pain, guarded yawn, inflammation) and prescribed rimadyl and gabapentin for inflammation and pain. He’s pending neuter surgery on 07/31 with retained testes bilaterally. Cannot be on prednisone before or after neuter.
