South Australia has recorded its first case of the tick-borne disease canine ehrlichiosis.

The disease, which can be fatal to dogs, was believed not to exist in Australia until a case was recorded in Western Australia in May last year.

South Australian Chief Veterinary Officer Mary Carr says dog owners need to ensure their dogs are on an appropriate tick repellent program and are checked for ticks regularly. She emphasises that if a dog that has been in an affected area starts to show symptoms such as fever, lethargy, bleeding, pain, and weight loss, seek a vet immediately.
