Crossed from another Forum DOG OWNERS WARNED TO STAY ALERT AS CASES OF MYSTERY ILLNESS EXPECTED TO REOCCUR We are warning dog owners to stay vigilant for the signs of seasonal canine illness (SCI), a mystery illness which in recent years made a number of dogs walked in woodlands suddenly become ill. Cases of SCI are usually seen from August to November with dogs showing clinical signs of vomiting, diarrhoea and/or lethargy within 24 to 72 hours of walking in woodland. Dog owners are advised to seek immediate veterinary advice should they see these signs in their dog following a woodland walk. Despite no definite cause being recognised, we have identified a number of common themes which may increase a dogs susceptibility to SCI. We are advising dog owners planning to visit woodlands this autumn to ensure that their pets are up-to-date with preventive treatments for external parasites such as Harvest mites. Products available without prescription may not offer sufficient protection against mites so please contact your local vet to discuss which options are suitable. Distance travelled may also be a factor. If you are travelling with your dog, ensure a supply of fresh water is always available and give your dog plenty of breaks from the heat of the car. Also bear in mind that accommodation such as conservatories and caravans heat up incredibly quickly and may lead to dehydration in your dog. We are continuing to ask dog owners who walk their dogs at any of the five study sites: Sandringham Estate or Thetford Forest, Norfolk, Clumber Park or Sherwood Forest, Nottinghamshire or Rendlesham Forest, Suffolk, to complete our online questionnaire at Seasonal Canine Illness - SCI | Animal Health Trust Charlotte Robin, our SCI Research Co-ordinator, said We desperately need information from dogs which have been walked at any of our study sites, even if they did not become ill. The information we can glean from owners of dogs who walked at the sites and didnt show clinical signs of SCI is just as important to our investigation, as information from affected dogs. We want to also highlight that dogs could be a risk of SCI walking at any woodland during autumn, so we are advising dog owners to remain vigilant and to seek veterinary advice immediately if they suspect their dog has SCI.
