MMM - Masticatory Muscle Myositis
My pup (DOB February 27th, 2012) developed MMM 3 weeks after her first set of shots. I noticed she could not open her mouth, took her to the Vet, and he thought it was Puppy Strangles. I Googled her symptoms and brought her back, so we did not begin her treatment for 2 more weeks. Her jaw muscles atrophied and her face "hallowed," so she was in the "Chronic" stage when we began the anti-rejection steroids, which she will take until a month after her first birthday. Her jaw muscles have returned, she is happy and appears healthy, however unless she is on antibiotics she has diarrhea.
MY QUESTION: Has anyone else experienced MMM in a puppy & started treatment in the chronic stage? If so, how did it all go?
I've checked multiple web sites and all say a pup who begins treatment in the acute phase has a good chance. regarding treatment begun in the chronic phase, all I can find are platitudes, such as "Dogs which are not treated until they are in the “chronic” phase don't fare as well as well..." and "Dogs which are not treated until they are in the “chronic” stage of MMM may be expected to have a less favorable prognosis..." Exactly how "Less favorable"? Can anyone be more specific? What percentage of dogs live? 90%? 10%?
If you have experienced this, please be completely honest with me. I need to know.
Thank you for reading all this.

Welcome! Sorry you have to deal with this. I have no experience with MMM, just wanted you to know that I wish the very best for you and your puppy. Have you been to the Cavalier Health website yet? It is an excellent source of health information.
Good luck and let us know how your puppy is doing. You'll find lots of support here.

Cavaliers are one of the few breeds with more than its fair share of MMM. Dr. Diane Shelton of the University of California at San Diego has specialized in this disorder. Her website is http://vetneuromuscular.ucsd.edu/
I suggest that you contact Dr. Shelton through her website -- http://vetneuromuscular.ucsd.edu/question.html -- and ask your questions to her and her staff. Here is a link to a rather informative article about MMM by Dr. Shelton and others, that is on her website: http://vetneuromuscular.ucsd.edu/pub...ons/Melmed.pdf

Thank you for your response. Dr. Shelton's lab did the blood test that confirmed this condition and I've already read her reports thoroughly. Trust me, when I said I researched the web beyond belief, I meant it. This is why I was hoping to find someone who has experienced this themselves. Unfortunately, although Cavaliers are indeed "one of the few breeds with more than its fair share of MMM," none of the people who have gone through this are reading this forum. Oh, well. Time to try something else...

Jodi, if Dr. Shelton cannot answer your question, I don't know who can. I think she has treated more cases of cavaliers with MMM than anyone else.
