Experts are warning dog owners to stay on their guard as a deadly canine illness returns.
Several dogs have been struck down with Seasonal Canine Illness (SCI), which has lead to some dogs losing their lives during the autumns of 2009, 2010 and 2011.
The Animal Health Trust (AHT) said they feared the pattern would continue this year and of 200 responses to a survey sent out in late August, 14 new cases of SCI have already been identified.
Dr Richard Newton, of the AHT, said: “Our SCI investigation has been ongoing since we were first alerted to the illness in the autumn of 2010.
“Since then we have had more and more cases reported to us each autumn, but thankfully the number of dogs which are surviving has increased.”
Symptoms of seasonal canine illness include vomiting, diarrhoea and lethargy.
The symptoms come on quickly, usually within 24 to 72 hours of dogs walking in woodland or near stagnant water.
Farrah Stevens, spokeswoman for AHT, said: “We still advise dog owners to stay vigilant and to seek veterinary advice if they see any of the clinical signs of SCI in their dog.”
