Sadly, most dogs with degenerative myelopathy eventually lose control of their legs, bladder and bowels completely, and need to be put to sleep. The average life expectancy of a dog with degenerative myelopathy is 1-2 years from diagnosis.
If your dog's back legs suddenly collapse, plan on an emergency vet visit at a local pet emergency hospital or your regular veterinarian's office. Sometimes dogs with IVDD can recover without surgery, but other cases require IVDD surgery in dogs.
For example, dogs who have experienced atrophy and muscle loss caused by injury or surgical recovery stand a good chance of regaining the strength in their back legs. However, dogs whose legs are weak due to a degenerative condition or other mobility conditions may never regain full use of their back legs.
The most prominent sign that you will notice is a complete relaxation of the body, your dog will no longer appear tense, rather they will “let go.” You will notice a slimming of the body as the air is expelled from their lungs for the last time and you may notice the lack of life in their eyes if they are still open.
Lack of mobility is a life threatening disease – dogs who can't get up or walk anymore usually are euthanized. This is the stage we are trying to prevent by intervening early. At this stage, the pet may resist, cry or even scream when the joint range of motion is tested.
How quickly does degenerative myelopathy progress? Unfortunately DM tends to progress very quickly. Most dogs that have been diagnosed with degenerative myelopathy will become paraplegic within six months to a year.
Degenerative myelopathy is not a painful condition and, as a result, affected dogs are generally well and keen to exercise, despite their disability. A German Shepherd Dog with degenerative myelopathy – the hindlimbs are weak and inco-ordinated, and the toes of the right hind paw are being dragged.
Canine degenerative myelopathy (DM) was previously known as chronic degenerative radiculomyelopathy (CDRM) and is a progressive degenerative spinal cord disease. Ultimately it is a fatal disease with devastating consequences for the dogs and can be distressing for owners caring for them.
Walking is a great way to strengthen your dog's back legs. If you're walking your pet, keep it slow and short. After all, a long walk could end up doing more harm than good. You could take your dog for a swim or try stretching your pet's hind legs for more strength.
The main orthopedic cause of hind-limb weakness in dogs is chronic joint inflammation/pain (osteoarthritis, degenerative joint disease). While the arthritis itself is obviously painful, it is frequently accompanied by muscle aches and pains, called compensatory pain.
Cardiac problems
Another potential cause of weakness in back legs of dogs is cardiac problems. The heart is responsible for pumping blood throughout the body, and if it is not working properly, the body may not receive enough oxygen. This can lead to weakness, fatigue, and even collapse.
Some common signs that it may be time to put your pup down include the inability or refusal to eat or drink, labored breathing, an inability to get up for potty times without help, urinary or fecal incontinence, and immobility. Essentially, this can come down to your dog's quality of life.
Many mobility issues can cause a dog's hind legs to give out and collapse underneath them suddenly. For example, a dog's back legs can collapse due to an injury, leg weakness in an older dog, arthritis, or a more serious health condition such as Degenerative Myelopathy.
Why does my older dog keep collapsing? If your elderly dog is collapsing repeatedly, the likelihood is it's down to an age-related condition such as diabetes or heart disease. You should seek advice from your daytime vet about the potential causes and solutions.
Treatment for Degenerative Myelopathy in Dogs
Veterinarians may be able to treat some related symptoms to relieve discomfort, but a healthy diet and plenty of exercise, including walking and swimming, are the main ways to keep dogs with the condition as mobile as possible.
Sadly, most dogs with degenerative myelopathy eventually lose control of their legs, bladder and bowels completely, and need to be put to sleep. The average life expectancy of a dog with degenerative myelopathy is 1-2 years from diagnosis.
One important indication that a dog is about to die is a decrease or loss of appetite. This appetite loss may be attributed to lack of interest in food or water, or the dog could be having trouble swallowing.
Yes, dogs with Degenerative Myelopathy should stay as active as possible. Keeping a DM dog active can actually help slow down the progression of the disease. Physical therapy and regular structured exercises, including walking, can help dogs with DM maintain muscle strength and minimize their risk of muscle atrophy.
Myelopathy describes any neurologic symptoms related to the spinal cord and is a serious condition. It occurs from spinal stenosis that causes pressure on the spinal cord. If untreated, this can lead to significant and permanent nerve damage including paralysis and death.
How is DM diagnosed? This disease will be suspected on the basis of breed, medical history, physical examination, and diagnostic tests. X-rays and other spinal imaging techniques will rule out other problems such as hip dysplasia and chronic arthritis, most often during the initial stages of DM.
Arthritis is a long-term condition that needs life-long management. Arthritis slowly worsens over time, but if well managed, most dogs can live happily for many years after diagnosis. Let your vet know if you think your dog's pain isn't well controlled or you see symptoms returning.
Severe Osteoarthritis (STAGE 4)
A dog often becomes restless when standing and may be reluctant to stand or move. Other signs include consistent severe lameness, weight shift and abnormal limb loading.
He has lost interest in all or most of his favorite activities, such as going for walks, playing with toys or other pets, eating treats or soliciting attention and petting from family members. He cannot stand on his own or falls down when trying to walk. He has chronic labored breathing or coughing.
