Polyradiculoneuritis is a devastating condition. It is a disease of sudden onset which causes weakness or paralysis in all four legs. In the United States it can be secondary to a bite from a racoon (Coonhound paralysis).
In Australia it is usually from an unknown cause. Recent studies indicate a link to the ingestion of raw chicken. It may also be a rare complication of a post vaccine reaction.
It is similar to Guillain-Barré Syndrome in humans.
Polyradiculoneuritis is likely due to an autoimmune reaction where the body attacks the nervous system resulting in damage to nerves and myelin (the insulating sheath that covers nerves).
There is no specific test for Polyradiculoneuritis. It is suspected if there is sudden weakness or paralysis in all four legs. Other diseases which may cause similar signs must be ruled out eg tick paralysis, snake bite
Which breeds are affected
Any breed can be affected but Jack russell terriers and West Highland terrier show up slightly more commonly than other breeds.
Signs of Polyradiculoneuritis
It may start with a stilted gait. Weakness usually starts in the hind legs and moves to the front legs. This weakness usually progresses to full paralysis and peaks at about 14 days. Some dogs may also have further complications - a change in their bark, facial muscle paralysis, difficult swallowing and in the worst of cases - breathing difficulties. Many dogs may be overly sensitive to touch as their superficial sensation remains intact
There is no specific conventional that is considered effective.
Nursing Care/ Home Care
These guys require a lot nursing care from owners. Feeding, watering, keeping clean from faeces and urine, assisting with urination and avoiding bed sores are all part of this process
