We wanted to make our clients aware we’ve had a case of seasonal canine illness
(SCI)🌳
For those who aren’t familiar with SCI, it is rare condition, characterised by rapid onset vomiting, diarrhoea and lethargy. Signs usually start within 24-48 hours of being walked in a woodland area. With prompt treatment most dogs recover but without supportive care dogs can rapidly become dehydrated which in severe cases may be life threatening. Cases are seen most commonly through the autumn months. Puppies and older dogs are often more severely affected. Whilst not every woodland area in the UK is affected, unfortunately Rendlesham and Tunstall Forests are known hotspots. Frustratingly the definitive cause of SCI is unknown, but research suggests harvest mites may play a role.
To the naked eye harvest mites look like very tiny orange dots. They are most often
found right up between your dog’s toes and in a small pocket in their ear flap. Whilst not every dog who has harvest mites will get SCI we recommend checking your dog regularly for harvest mites, especially if walking in woodland areas. Harvest mites may be prevented/treated with a Fipronil spray. If you would like further information on this please call your local branch for further advice.
However it’s important to note, whilst harvest mites may be involved the research is inconclusive, so during the autumn months we would still advise owners exercise caution when considering walking in Rendlesham or Tunstall forests, especially if your dog is under a year old, elderly, or suffering with other health issues. If possible, it is recommended to avoid the forests altogether until after the first frost.
