    Well, it's official - Ilsa has acute masticatory muscle myositis (MMM).

    In laymen's terms, it's an inflammatory disease that affects the "chewing" muscles. These muscles are special in that they are the only muscles in the body that has 2M muscle fibers. Basically, MMM is caused by the dog's immune system attacking these specific muscle fibers. Sadly, no one really knows why the immune system does this, nor is it known if it's hereditary.

    She's on prednisone now. She'll be on it for as little as 4-6 months... or she might have to be on prednisone for life. :( We think we caught it soon enough though, so hopefully she won't need to be on it lifelong.

    We've also been instructed to get her toys and chewies to encourage use of her jaw muscles as a form of physical therapy. So, the lucky girl is getting an early Christmas present of bully sticks and other yummies today!

    Poor girl, she can't seem to catch a break. I'm just hoping she doesn't have to be on pred for life. :(

    Very true! Ronin is an Energizer Bunny, he just keeps going and going and going. I recently talked to the people that have his sire, Hunter. Hunter is 9, and he's still got just as much spunk and energy as he did when he was 18 months old. He's never been sick a day in his life, he runs circles around his younger housemates. He's not showing any signs of getting old... I can only hope Ronin follows in his father's footsteps. Here's a photo of Hunter at age 8, chasing Ilsa around:

    *sigh* If only all dobermans lived as long and as "intensely" as 'lil Hunter. It's no fun watching Ilsa slow down. :(

    Could you please go into more detail the signs and symptoms of this condition is? What you noticed, how you noticed, how long it took the vet to diagnosis etc..?

    Oh Hunter is AMAZINGLY handsome!

    It is really disheartening to see all the health problems and lack of longevity in this breed..........well bred and tossed together alike :(

    Sure.

    First, I noticed that she wasn't yawning "all the way". She'd open her mouth about 75% of the way, then she'd kind of "chatter" her jaws and stop yawning. I figured she was just not in the mood to have a nice, long yawn.

    A few days later, she stole a piece of pizza. She wouldn't drop it, so I pried her jaws open. She let out a yelp, then ran and hid. I felt bad, I thought I'd pinched her lip on a tooth or something. But curiosity got the best of me, so I tried to open her mouth - basic dental exam, I do it every week or two to all the dogs. She screamed and jumped into my fiance's lap, and just trembled for about 10 minutes... BIG TIME pain.

    It was :after hours", so I emailed the lady that owns Ronin's sister - an amazing veterinarian in Wisconsin. She emailed me back with a whole slew of possible problems... and MMM was at the top of her list.

    When I took Ilsa to my local vet, he confirmed my friend's "e-diagnosis".

    Her symptoms (other than the obvious trismus) include a "sunken" appearance to her face and jaw - where the muscles were being broken down. Her lymph nodes were swollen, and her eyes looked a bit bulgy.

    Tests for it include blood tests - including the 2M Antibody blood test, but sometimes a muscle biopsy is needed.

    It can develop at any age, and is most common in GSDs, dobes, goldens, labs and cavalier king charles spaniels.

    If not caught in time, the trismus can progress so far that the jaw can't open at all, or open very little - the longer the muscle is attacked, the more scar tissue is formed. Liquid diets are then needed.

    I don't know Ilsa's history, but do you have any contact with people who own siblings or her parents? It would be interesting to see if any have developed this also.

    I'm so sorry :( I'm crossing my fingers that the pred will work wonders and the bullysticks will work jaw muscles. WORK THAT MOUTH ILSA!!!

    Yep - I've known her parents for years, grandparents, and a few great-grandparents. To my knowledge, this is the first case of it in her immediate pedigree. We're going to do more research, but right now it looks like hers is an isolated case... which many cases of MMM are, apparently.

    I'm sorry to hear this. Hugs & kisses to Ilsa.
     
  20. SD, I am so sorry to hear about Ilsa. Sending superb chew chew chew vibes. Maybe knuckle bones would be good too? I know my dogs chew more intently and longer on those than anything else.

    I am so glad you got great veterinary advice, and hope you can get her off the pred as soon as possible.

    Get well soon Ilsa!!!
