The cases, which were reported at the end of last year, brought the total number of cases in 2019 to 29.
The latest confirmed cases were located in Devon, Rutland, County Tyrone and Cheltenham. The highest number of confirmed cases last year were in Greater Manchester, Dorset, Devon and the New Forest in Hampshire.
David Walker, the UK’s leading expert on the condition, from Anderson Moores, said: “We are sad to announce more cases from 2019, as we are now in the time of year when cases are most common.
“Further confirmed cases mean it is understandably very worrying for dog owners; however, this disease is still very rare, so we’re advising dog owners to remain calm but vigilant, and seek advice from their local vet if their dog develops unexplained skin lesions.
“While there is currently no known way to prevent a dog from contracting the disease, any concerned dog owners should visit www.vets4pets.com/stop-alabama-rot/ for advice and a map of confirmed cases.”
Dr Huw Stacey, vet and director of clinical services at Vets4Pets, said: “While it is understandable that dog owners will be worried by Alabama Rot, it is still a very rare disease and we’d encourage owners to continue exercising their pet.
“If a dog becomes affected, the best chance of recovery lies with early and intensive veterinary care at a specialist facility such as Anderson Moores.”
He added: “Treatment is supportive, but is only successful in around 20 percent of cases, which is why we’re encouraging all dog owners to use the online interactive guide to help them understand the clinical signs and confirmed locations of the condition, and visit a vet if they have any concerns.”
