The exact cause has not yet been established. It is thought that the immune system attacks the body’s own nerves; a predisposition may also play a part.

When should you see a vet?
Sudden weakness always needs a vet straight away, especially if:
- your dog suddenly becomes weak or can no longer get up,
- their breathing becomes laboured or shallow,
- they have trouble swallowing, bark hoarsely or lose their voice.
Polyradiculitis is an inflammation of many nerve roots. It often leads to weakness or even paralysis within a few days, usually rising from the hind legs. Sudden weakness always belongs at the vet right away, especially if breathing becomes harder.
What is polyradiculitis?
In polyradiculitis, more precisely polyradiculoneuritis, the roots and sections of the nerves outside the brain and spinal cord become inflamed. It is believed that the immune system attacks the body’s own nerves, sometimes after an infection. In North America the disease is also known as “coonhound paralysis”, because there it can occur after contact with raccoons. Overall it is rare, but among the sudden-onset nerve diseases in dogs it is one of the most common.
How do you recognize polyradiculitis?
- sudden weakness, dragging gait, usually starting in the hind legs
- weak or absent reflexes
- changed, hoarse voice when barking
- in severe cases, paralysis of all legs and breathing problems
How does the vet diagnose polyradiculitis?
Through a detailed clinical and neurological examination. This is supplemented by blood tests, imaging and sometimes special nerve tests. These help rule out other causes of sudden weakness.
How does the disease progress?
Treatment consists mainly of good nursing care and physiotherapy, in severe cases at a clinic. If the breathing muscles become weak, this is life-threatening. Many dogs recover, but slowly: it often takes weeks to months. In some, a weakness remains.
How you can support your dog
- a calm environment and a soft, well-padded place to lie
- regular repositioning if your dog cannot get up alone
- help with eating, drinking and grooming
- the exercises the physiotherapist or the vet shows you
