DOG owners are being urged to watch out for signs of Alabama rot following the start of the peak season for the deadly disease.

The condition, which causes acute kidney failure and has killed several dogs in the New Forest, usually strikes between November and May.

Now dog lovers are being warned to be extra vigilant, especially after taking their pet for a walk in the countryside.

More than 100 dogs in the UK have died from the disease - including at least 18 in the Forest and other parts of Hampshire.

Caroline Kisko, secretary of the Kennel Club, said: "Although it's very rare, affecting an extremely low percentage of dogs, the condition is potentially life-threatening.

"We're asking owners to look out for any signs of Alabama rot during the winter months and to take action right away.

"Any dogs with unexplained skin lesions should be taken to their vet as soon as possible. These skin changes are usually found on their paws or lower legs, but may also appear on their head, face or lower body.

"Dogs who have contracted the disease may also become tired, disinterested in food, or present other signs of illness such as vomiting or diarrhoea.

"Although these signs may not necessarily mean your dog has Alabama rot, acting quickly and speaking to a vet to determine what's wrong is the best course of action."

Huge amounts of research have been carried out in recent years but the cause of the disease is still a mystery.

No evidence has been found to suggest it is triggered by bacteria, toxins or radiation. Researchers say the high number of cases seen in winter and spring mean it could be related to mud or water.

Ms Kisko added: “To lower any risk of your dog contracting Alabama rot, it’s advisable to keep them away from very muddy areas.

"You should wash wet or muddy dogs straight after a walk and regularly check their body for anything that’s different.

“While a distinct seasonal pattern is suggested, we must continue to research this deadly disease and ensure all dog owners are aware of the signs and symptoms so they are able to seek veterinary advice immediately.”

The disease appeared in America in the 1980s and later spread to the UK. Cases have been confirmed in at least 27 counties since 2012.
