Older dogs' back legs give out due to age-related issues like osteoarthritis, nerve damage (like degenerative myelopathy or slipped discs), muscle loss (sarcopenia), and sometimes underlying conditions like cancer or infections, causing pain, weakness, and poor coordination, often progressing gradually but sometimes suddenly. Prompt vet care is essential for diagnosis, as many treatable conditions mimic these signs, leading to better mobility and quality of life.
With support from orthopedic braces, a healthy diet, regular exercise, as well as homeopathic support, your older dog may have many happy and healthy years ahead, free of back leg collapse. Talk to your vet and ask if a hip brace may alleviate your older dog's hind leg weakness.
You'll know your senior dog is suffering from signs like mobility issues (limping, difficulty standing/stairs), behavior changes (lethargy, irritability, hiding, less interest in play), appetite/thirst changes, disorientation, incontinence, restlessness at night, or labored/heavy breathing, indicating pain or discomfort beyond normal aging, and a vet visit is crucial for diagnosis and relief.
General Symptoms of Degenerative Myelopathy in Dogs
Disease progression can vary, but the majority of dogs are euthanised on welfare grounds within 6-18 months of the symptoms first becoming apparent. Even though there is no pain involved, the impact on their quality of life can be drastic.
There are many reasons why a dog's legs may appear to give out. Common reasons for hind leg collapse in senior dogs include osteoarthritis, intervertebral disc disease, metabolic disorders, vestibular disease, heart disease, and degenerative myelopathy.
Key Canine End-of-Life Indicators
The Five Stages of Degenerative Myelopathy
A frequent cause of sudden hind limb weakness in older dogs is Intervertebral Disc Disease (IVDD). This condition develops when the discs between spinal vertebrae become compressed or rupture, exerting pressure on the spinal cord. The result can be pain, coordination problems, or even paralysis in the hindquarters.
Dog stroke symptoms include sudden head tilting, circling, loss of balance, and one-sided weakness. Call an emergency veterinary facility immediately if these symptoms appear, as quick treatment improves outcomes. Many dogs recover well from strokes with prompt, appropriate veterinary care.
The first signs of Cushing's disease in dogs often involve increased thirst (polydipsia), frequent urination (polyuria), increased appetite (polyphagia), and excessive panting, along with lethargy and a pot-bellied appearance, often accompanied by skin issues like thinning, hair loss (especially on the flanks/tail), and slow-healing wounds.
Recognizing Changes in Behavior and Personality
One of the earliest signs your dog is dying of old age is a noticeable change in their behavior and personality. Senior dogs may become more irritable or withdrawn. They might show less interest in activities they once loved, such as playing fetch or going for walks.
Silent pain in dogs refers to chronic or ongoing discomfort that isn't obvious through visible signs like limping or whining, but still affects their behavior, movement, and well-being. Pain and behavior are closely connected.
Cancer causes approximately half of the deaths in dogs over the age of 10. “Cancer” is actually a blanked term for a collection of related disease, and each has a unique prognosis. Cancer occurs when there is an uncontrolled division of abnormal cells which spread into the surrounding tissue.
Recovery from back leg weakness may be possible, but this greatly depends on what's causing the loss of leg strength. For example, dogs who have experienced atrophy and muscle loss caused by injury or surgical recovery stand a good chance of regaining strength in their back legs.
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.
The following is a rough guide to when dogs are considered senior: Small dogs (under 20 lbs): between 7-10 years old. Medium dogs (21-50 lbs): from 7 years old. Large (51-90 lbs) and giant dogs (over 90 lbs): from 5-6 years old.
The warning signs of stroke include:
Signs of Strokes in Dogs
It can be challenging knowing if your dog has had a stroke as the associated signs can also indicate other health conditions. Stroke signs in dogs may include: Sudden loss of balance or coordination. Head tilting or compulsively walking in circles.
Other signs and symptoms may include:
Warning signs a dog is dying include significant lethargy, loss of appetite/thirst, difficulty breathing (labored, panting at rest), incontinence (bladder/bowel), confusion, restlessness or withdrawal, decreased mobility (weakness, stumbling), and increased signs of pain (whining, aggression) as their body systems begin to shut down. These physical and behavioral changes signal a decline, and consulting your vet is crucial for guidance on comfort and quality of life.
What are the main signs and symptoms dog's back legs not working?
Breed predisposition
Sudden changes in your dog's behavior can indicate serious health issues. If your dog is in pain, has a limp, or is unable to rise, these symptoms require further investigation. Difficulty breathing, refusing food or water, or being unable to get up to eliminate are major signs. Loss of balance is also important.
Symptoms of degenerative cervical myelopathy
pain or stiffness in the neck. tingling or numbness in the arms or legs (often starting in fingertips or toes) or less commonly in the body. change or loss in the manual coordination or dexterity in the hands (e.g. fastening buttons or tying shoelaces)
2) Stops Eating/Drinking
If your dog is at this point, you can offer them the tastiest treat imaginable and they will not eat it. They will also stop drinking water. This is due to the beginning of their organs shutting down. They no longer have the sensation of hunger or thirst.
