Adult Onset Neuropathy (AON)
Adult Onset Neuropathy (AON) is a neurological disorder that affects dogs. It is characterized by a progressive weakness in the hind limbs, which later spreads to the front limbs. Additionally, it can compromise the dog’s ability to eat, drink normally, and move around. Here are some key details about AON:
- Clinical Signs: AON typically begins between 7½ to 9 years of age. The initial signs include weakening and unsteady hind limbs, followed by uncoordinated movement. Eventually, the weakness extends to the front limbs, and in severe cases, there may be difficulty in swallowing
- Inheritance: AON is an autosomal-recessive condition unique to Cocker Spaniels. This means that a dog must inherit two copies of an abnormal gene (one from each parent) to be affected by the disease. Dogs with only one copy of the abnormal gene are carriers but do not show signs of the disease.
If you have a Cocker Spaniel or suspect AON, consider DNA testing to understand your dog’s genetic status and make informed breeding decisions. The Kennel Club provides information on testing and breeding advice
Remember, early detection and responsible breeding practices can help manage this condition effectively.
