The age at onset is 5 to 14 years, which corresponds to the third to sixth decades of human life. Although a few cases have been reported in other large breeds of dogs, the disease appears with relative frequency only in the German Shepherd breed, suggesting that there is a genetic predisposition for German Shepherd dogs (GSD) in developing DM. The work presented here and by others on the nature of DM has been performed in the German Shepherd breed. Care must be taken in extrapolating this information to other breeds of dogs. It is currently not known whether the exact condition exists in other breeds of dogs. Many dogs may experience a spinal cord disease (myelopathy) which is chronic and progressive (degenerative); but, unless they are caused by the same immune-related disease which characterizes DM of GSD, the treatments described herein may be ineffectual. The breeds for which there is data to suggest that they also suffer from DM of GSD are the Belgium Shepherd, Old English Sheep Dog, Rhodesian Ridgeback, Weimaraner and, probably, Great Pyrenees. Confirmation of the diagnosis is important in other breeds before assuming that they have DM of GSD.
Diagnosis of DM is made by a history of progressive spinal ataxia and weakness that may have a waxing and waning course or be steadily progressive. This is supported by the neurologic findings of a diffuse thoracolumbar spinal cord dysfunction. Clinical pathologic examinations are generally normal except for an elevated cerebral spinal fluid (CSF) protein in the lumbar cistern. Electromyographic (EMG) examination reveals no lower motor unit disease, supporting the localization of the disease process in the white matter pathways of the spinal cord. Spinal cord evoked potentials recorded during the EMG do show changes which help determine the presence of spinal cord disease. Radiographs of the spinal column including myelography are normal (other than old age changes) in uncomplicated DM. Unfortunately, myelography can be associated with worsening of clinical signs and carries some degree of risk for certain patients.
Dogs afflicted with DM have depressed lymphocyte blastogenesis to plant mitogens. The depression of their cell mediated immune responses correlates with the clinical stage and severity of the disease. Furthermore, this suppression has been shown to be due to the genesis of a circulating suppressor cell. Some dogs with DM exhibit antigen-binding cells specific to canine myelin basic protein. Immunoglobulins have been shown to be bound within lesions within the spinal cords of dogs with DM. These patients also show increased circulating immune-complexes in their sera. The antigens in these immune-complexes have been examined and appear to be markers of inflammation as they have been found to exist in patients who have other inflammatory diseases of the central nervous system. 2-Dimensional electrophoresis of CSF proteins indicates that the elevated proteins in the CSF of DM patients represent changes which are related to inflammation. While these changes are not specific for DM, the other conditions in which the inflammatory proteins have been found in CSF can be differentiated by clinical signs.

The Disease:
Degenerative Myelopathy (DM) was first described as a specific degenerative neurologic disease in 1973. Since then, much has been done to understand the processes involved in the disease and into the treatment of DM. Hopefully, this will help you understand the problem and to explain further the steps that can be taken to help dogs afflicted with DM.The age at onset is 5 to 14 years, which corresponds to the third to sixth decades of human life. Although a few cases have been reported in other large breeds of dogs, the disease appears with relative frequency only in the German Shepherd breed, suggesting that there is a genetic predisposition for German Shepherd dogs (GSD) in developing DM. The work presented here and by others on the nature of DM has been performed in the German Shepherd breed. Care must be taken in extrapolating this information to other breeds of dogs. It is currently not known whether the exact condition exists in other breeds of dogs. Many dogs may experience a spinal cord disease (myelopathy) which is chronic and progressive (degenerative); but, unless they are caused by the same immune-related disease which characterizes DM of GSD, the treatments described herein may be ineffectual. The breeds for which there is data to suggest that they also suffer from DM of GSD are the Belgium Shepherd, Old English Sheep Dog, Rhodesian Ridgeback, Weimaraner and, probably, Great Pyrenees. Confirmation of the diagnosis is important in other breeds before assuming that they have DM of GSD.
Diagnosis of DM is made by a history of progressive spinal ataxia and weakness that may have a waxing and waning course or be steadily progressive. This is supported by the neurologic findings of a diffuse thoracolumbar spinal cord dysfunction. Clinical pathologic examinations are generally normal except for an elevated cerebral spinal fluid (CSF) protein in the lumbar cistern. Electromyographic (EMG) examination reveals no lower motor unit disease, supporting the localization of the disease process in the white matter pathways of the spinal cord.

While these changes are not specific for DM, the other conditions in which the inflammatory proteins have been found in CSF can be differentiated by clinical signs. The 2-dimensional electrophoresis of CSF proteins appears to be one of the most specific change seen in DM. Recently, we have found that CSF levels of the enzyme, acetylcholinesterase, are elevated in patients with DM. Again, this occurs in other forms of central nervous system inflammation in dogs. However, when combined with the history, neurologic signs, CSF protein concentration and EMG, the elevated CSF acetylcholinesterase level helps confirm the diagnosis. This allows the inclusion of DM in the diagnosis, even if other problems are uncovered during the examination.
The gross pathologic examination of dogs with DM generally is not contributory toward the diagnosis. The striking features being the reduction of rear limb and caudal axial musculature. The microscopic neural tissue lesions consist of widespread demyelination of the spinal cord, with the greatest concentration of lesions in the thoracolumbar spinal cord region. In severely involved areas, there is also a reduced number of axons, an increased number of astroglial cells and an increased density of small vascular elements. In the thoracic spinal cord, nearly all funiculi are vacuolated. Similar lesions are occasionally seen scattered throughout the white matter of the brains from some dogs, as well. Many patients have evidence of plasma cell infiltrates in the kidneys on throughout the gastrointestinal tract, providing a hint to the underlying immune disorder causing DM.
During the past two decades, we, at the University of Florida, have provided important new insights into the pathoetiology of DM. The release of antigens during the disease process could explain the immune deficits seen in DM and suggests that processing these immune-complexes by circulating macrophages leads to the development of the circulating suppressor cells that were previously noted. This provides a logical explanation for the presence of immune abnormalities in GSD with DM. Electrophoresis of immune-complexes demonstrates that the proteins present are inflammatory proteins which increase in inflammatory diseases of the dog nervous system. It is hoped that working with the antigens present in the immune-complexes will lead to a major breakthrough in our understanding of DM and that this also could lead to an early serodiagnostic test for the condition. However, the development of a serodiagnostic test will await the availability of antibodies specific to unique markers within the inflammatory proteins of DM dog immune-complexes.
While the cause of the altered immune system is not known, what is increasingly clear is that DM is caused by an autoimmune disease attacking the nervous systems of patients, leading to progressive neural tissue damage. In many respects, DM is similar to what has been discovered about the pathogenesis of Multiple Sclerosis in human beings. In fact, based upon new data concerning the pathology of MS, we can now say with some degree of certainty that DM is MS in dogs. We believe that, due to some triggering factor, immune-complexes circulate. These immune-complexes lead to endothelial cell damage in the vessels of the CNS. Subsequently, fibrin is deposited in the perivascular spaces. When this degrades (point of action of aminocaproic acid), inflammatory cells are stimulated to migrate into the lesions. The inflammatory cells release prostaglandins and cytokines (point of action of vitamin E and C) which leads to the activation of tissue enzymes and the formation of oxygen free-radicals (point of action of acetylcysteine) which, in turn, leads to tissue damage. Treatment of DM of GSD, which we recommend, is directed at these pathologic processes.

Siberian ginseng is derived from the root of a large, spiny shrub (Eleutherococcus senticosus) found in Siberia and northern China. It is a relative of true ginseng, but has entirely different properties. Siberian ginseng has "adaptogenic" properties and reduces physiologic responses to stress. Scientific investigations suggest it increases physical performance and endurance and improves immune function. For dogs with DM, given 1 capsule twice a day.
Bromelain is an extract of pineapple stems which has the property of decreasing circulating immune-complexes. As such, there is no Western medicine which is its equal. Since many of the complications and the direct initiation of the immune damage may be caused by the elevated immune-complexes in DM, bromelain may be an important key in helping to control the progression of DM. Curcumin (the yellow pigment of turmeric plants) is a potent anti-inflammatory agent. Bromelain and curcumin have a synergistic effect whereby they assist the absorption of each other from the gastrointestinal tract, increasing their potency. As such, they should be given together. Many health food stores carry combinations of bromelain and curcumin. For dogs with DM, give 400-500 mg of bromelain with 500-400 mg of curcumin twice a day. (Curcumin is found in low concentrations in the spices turmeric and yellow mustard. As such, it is possible to replace the "capsule" form by adding 1-2 Tbs of turmeric and 1-2 tsp of dry yellow mustard to the diet.)
Feverfew is a natural NSAID compound without the side-effects of prescription drugs. It can be used in dogs with pain or arthritis to help reduce inflammation and discomfort. I do not recommend it for routine use; but, if your dog has pain from arthritis, give 1 capsule every 8-12 hours as needed. You can use this for 5 days out of the week, safely.
Note: WestLab Pharmacy has developed a palatable vitamin/mineral/herb product (Antiox-Q) which contains bovine cartilage, coenzyme Q, vitamin E, GLA, omega fatty acids, selenium, ginkgo, bromelain, curcumin, olive oil and B complex. This product contains the correct dosage of these compounds and only needs the addition of vitamin C, the ginsengs, green tea and grape seed to be complete. They may be contacted at 1-(800)-4WESTLA [1-(352)-373-8111, locally].

Medication:
Over the last 2 decades, we have found 2 medications which appear to prevent progression or result in clinical remission of DM in many (up to 80%) of the patients. These medications are aminocaproic acid (EACA) and n-acetylcysteine (NAC). We recommend giving EACA as a solution, using the generic product. This product, while designed for injection, can be mixed with chicken broth to provide a palatable solution for oral usage. We mix 2 parts of aminocaproic acid solution (250 mg/ml) with 1 part chicken broth and give 3 ml of this mixture orally every 8 hours. In our experience, this mixture has been equally, if not more, effective to the tablet form of EACA. Besides, the solution is much less expensive than the tablets. The generic form of EACA solution can be obtained from American Regent, 1-(800) 645-1706 (outside of NY). The generic drug from American Regent may be obtained through prescription with the help from a local pharmacy. An alternative source for EACA is to have a compounding pharmacy make the solution from chemical grade EACA. One such pharmacy is WestLab Pharmacy in Gainesville, FL. They can be reached at 1-(800) 4WESTLA [1-(352) 373-8111, locally] and can mail the medication and bill the client directly. The only side effects that have been attributed to EACA have been occasional gastrointestinal irritation. This presents a problem only in a few patients, usually who have pre-existing GI problems that the medication might exaggerate.by yellowrose of Texas on 11 June 2009 - 07:06
This presents a problem only in a few patients, usually who have pre-existing GI problems that the medication might exaggerate. A local pharmacist can help in determining whether any additional drugs might be contra-indicated or lead to possible drug-interactions with the recommended therapy. The only known interaction is with estrogen compounds; but, only in high doses.
Acetylcysteine is a potent anti-oxidant which has powerful neuroprotective effects. We give 75 mg/kg divided in 3 doses a day for 2 weeks. Then, we give the 3 doses every other day. The N-acetylcysteine comes as a 20% solution and must be diluted with chicken broth (or other compatible substitute) to 5%. Otherwise, it will cause stomach upset. This new treatment is expensive unless purchased through compounding pharmacies. Again, WestLab Pharmacy has this product and can send it to clients upon veterinary prescription. Using N-acetylcysteine at the above dosing does not appear to have side-effects. It can produce vomiting and may increase the bleeding time. The GI upset is likely due to the sodium content of the pharmaceutical product, which requires high concentration of base to buffer to pH 7.4. By reducing the pH during preparation, WestLab's product does not have as many side-effects. Giving fresh ginger 30 minutes before and giving the NAC with food (or on a full stomach) often reduces this effect.
The combination of aminocaproic acid, N-acetylcysteine, dietary supplements and exercise is the best treatment we have been able to discover to date. It corrects those aspects of the immune dysfunction which we can treat, based upon our belief that DM is an immune-mediated inflammatory disease. We always hope that all patients will respond to our treatment protocol. Unfortunately, it does not work in all cases; however, this combined treatment has been up to 80% effective in patients diagnosed at the University of Florida. The chances of successful treatment are improved if the therapy is begun early in the course of DM rather than later. A response to the drugs should be evident within the first 7-10 days. There is no other medications that we have found to provide any real benefits in the long term treatment of DM. Further information about other treatments may be found in Current Therapy X, pages 830-833 and in Vet. Clin. Nor. Am. 22:965-971, 1992.
Many of the old and new flea product can cause problems when certain neurologic conditions are present. As such, we recommend using boron, pyrethrums and Precor as the main control methods. Of the new medications, Frontline Spray and Revolution may be safe to use.
The traditional Chinese art of insertion of needles into various specific points of the body (with injection of small amounts of fluid or electrical stimulation) has been shown to provide analgesia and relief from acute and chronic pain. This has the advantage of having none of the side-effects of analgesic drugs. In addition, acupuncture can do no harm.

Other Supportive Measures:
Heartworm medication:
Since the monthly heartworm medications (Heartgard, Heartgard plus and Interceptor) increase immune responsiveness, we do not recommend using these products. Instead, we recommend plain diethylcarbamazine (DEC or Filaribits) which must be given daily. I do not recommend Filaribits plus (some dogs experience liver problems using it). If your dog is currently taking a monthly heartworm preventative, you must give one last dose and start the daily medication the next day. This is because the medications work at different points in the heartworm "life-cycle". Revolution, which is a new topical heartworm preventative, does not alter the immune response like the other monthly products. As such, Revolution should be safe to use in DM to control internal (and external) parasites.Flea prevention:
Many of the old and new flea product can cause problems when certain neurologic conditions are present. As such, we recommend using boron, pyrethrums and Precor as the main control methods. Of the new medications, Frontline Spray and Revolution may be safe to use.

One the other hand, DM patients who have concurrent arthritis may benefit from acupuncture therapy.
In many cases of degenerative joint disease with arthritis, recent studies have suggested that glycosaminoglycans and chondroitin sulfate may help reduce pain and inflammation from osteoarthritis, assisting in the healing process. While these products are available through health-food stores or a pharmaceutical medication through your veterinarian, you can give these to your dog directly by giving cooked cartilage. Sources of dietary cartilage would included cooked and "de-bone" chicken wings or using cooked spare ribs as the meat source in the diet. Why pay for cartilage products if it can be gotten for free in the dietary source. Some people taught the benefits of shark cartilage, but there are no scientific studies to support these claims. (It is also ecologically unsound to kill sharks to harvest their cartilage.) On the other hand, increase dietary cartilage can do no harm, particularly in the face of arthritis. In DM patients with arthritis, I recommend 1-2 grams of dietary cartilage with each meal. Another alternative is bovine gelatin (Knox gelatin or Knox Nutrajoint) which can be added to the food (1-2 packages per feeding). In some dogs, using glucosamine/chondroitin sulfate complex will be beneficial in controlling joint pain and stimulating healing; however, dietary cartilage has these compounds along with other important ingredients. Forms of glucosamine/chondroitin sulfate complex are available at health food store. (These are cheaper than products available from your veterinarian and may work as well) I recommend around 1200 mg of glucosamine and 1500 mg of chondroitin sulfate daily, if other forms of cartilage are not available.
DM progresses at different rates and "stress" plays a role in its advancement. Minimizing stressful situations is important where possible. While anesthesia does not appear to cause problems with DM; in the past, even minor invasive surgical procedures can result in a marked increase in clinical signs of DM. Unfortunately, the worsening caused by surgical stress can be irreversible. Due to the advent of N-acetylcysteine therapy and being more attentive to the continued exercise of hospitalized DM patients, we now have been successful in performing many surgical procedures in these dogs. These have included cervical and thoracolumbar disc surgery and total hip replacement. Before aggressive surgeries are considered, it is best to determine that the patient's neurologic status is stable. Post-operative physical therapy remains crucial in getting patients on their feet quickly.
Note: If your dog already has DM, you should consider treatment with the above natural products and more traditional aminocaproic acid and acetylcysteine medications. Use the aminocaproic acid and acetylcysteine for the first 2 months of therapy and then see if they can be withdrawn (without signs of deterioration). If so, then continue with the natural approach from that point on.

The Future for DM:
The key to DM in the future is likely to be prevention. While it may be necessary to wait for the next generation of GSD to see whether the principles laid down here work, they can do no harm. Science is only beginning to understand the fragile nature of DNA and how natural healing can be hampered by dietary and environmental toxins. The body is endowed with a tremendous capacity to heal, if we do nothing to interfere with this process. We are the keepers of our pet's health. We must empower ourselves to accept this responsibility.This article complimets of my friend , Dr. Melvin Massey, PHD. DVM

THANKS YR!
Someday I hope they find a cure...or can weed it out of the breed (in a perfect world).
Not sure if it is possible...and it does mimic MS in humans in fact I was trying to get the MS drugs for my pooch
before he passed but was never able too.
It is not fun to watch a dog go through DM and there is not much to slow it down.
I tried many things with my old GSD who finally had to be put down because of the disease.
Once diagnosed it is important to stop all innoculations in my opinion and/or flea/tick prevention.
Anything that will compromise the immune system is not good at all.
Great information!

FROM WHAT I HEAR, THIS IS A HARD DISEASE TO PIN POINT AT FIRST..THERE IS A DOG LOCALLY, THAT MAY HAVE DM..HE IS DRAGGING ONE FOOT , AND HE STUMBLES LIKE HE IS DISORIENTED. SPINAL EXRAYS WERE DONE AND HIS HIPS ARE OK.
HE EATS, DOESNT WHINE, JUST STARTED THIS ODD REAR END UNSTABLE WALKING ABOUT 7 MOS AGO. DOG IS ABOUT 5 YEARS OLD.
