Osteoarthritis of the hips and knees may eventually lead to hind leg weakness. This may cause your dog to have difficulty rising or walking and you may notice his or her hind legs collapsing. Additionally, arthritis may affect the front legs, back, and other joints.
Degenerative myelopathy is a condition that affects the nerves in the lower spine. It causes weakness, gradual paralysis of the hind legs, incontinence, and can sometimes even affect the front legs. Most dogs with degenerative myelopathy develop symptoms at around nine years old.
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.
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.
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.
If your dog is truly unable to walk, you must take him in for a veterinary examination immediately. A dog's inability to walk is indicative of a very serious underlying condition. Joint disorders are easier to treat than spinal cord issues, though all are challenging.
Late Degenerative Myelopathy
Most vets will recommend euthanasia before your dog reaches this late stage of degenerative myelopathy, this is because the symptoms become extremely debilitating. They include: Total paralysis of the hind legs. Jerky and uncontrollable movements in the hind legs and tail.
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.
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.
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.
Now, you and I both know dogs do have back legs but the facts are they don't really use them consciously as all they tend to use are their front legs which they know they have. If you like, their back legs just follow their front legs automatically.
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.
Severe Vestibular Disease
Vestibular disease refers to a problem with a dog's balance system. Most commonly, older dogs are affected by the idiopathic form, known as old dog vestibular syndrome, which comes on suddenly and severely, but oddly enough, improves on its own within a few days.
Degenerative myelopathy tends to affect dogs over the age of eight years old. The exact cause is unknown although it is thought to be a genetic mutation. Symptoms include wobbling, stumbling, weakness (such as shaking) and collapse.
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.
What breeds are most commonly affected? A genetic mutation, SOD-1, has been identified as a major risk factor for DM. DM is considered a disease of middle-aged to older dogs including German Shepherds, German Shepherd crosses, Siberian Huskies, and Collies.
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.
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.
How is it diagnosed? Degenerative myelopathy (DM) can only definitively be diagnosed by identifying classic microscopic changes in the spinal cord on autopsy. DM is strongly suspected in dogs where all other causes for neurologic disease are ruled out.
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 a Senior Dog
Walking is an excellent, low-impact exercise that promotes a healthy body and mind for both you and your dog. As your dog ages, you'll want to pay attention to your pace, the weather, and how your dog seems to feel during and after the exercise.
This dog massage therapy technique is intended for your dog's back legs and glutes. Using gentle pressure, press both thumbs into the thigh or glute muscle, and make a backwards “c.” Slowly work your way across the entire muscle, making these clockwise thumb circles.
How to Fix It. When muscle atrophy in dogs is caused by inactivity, it is often possible to reverse the muscle loss with exercise and adequate nutrition. As dogs get older, their nutritional needs may change. They may also become sensitive to certain nutrients.
