SCI season has started - be vigilant .
‼️‼️UK DOG OWNERS‼️‼️
Seasonal Canine Illness has been confirmed in Nottingham. Please check your dog's for harvest Mites (tiny red mites) on the skin, especially on legs.
Vet appointment ASAP if lethargy, sickness etc.
Seems to effect dogs walked in woodland areas not normally known to the dog.
Seasonal Canine Illness (SCI) is a potentially serious and sometimes fatal condition that affects dogs 24-72 hours after walking in woodland areas, most commonly between August and November. Symptoms include vomiting, diarrhoea, lethargy, abdominal pain, and muscle tremors. The cause is unknown, though harvest mites have been a focus of research. There is no specific test or cure, so prompt veterinary attention, supportive care like IV fluids, antibiotics, and anti-sickness medication, is crucial for recovery.
What to Look For
Dogs with SCI develop signs of illness within a few days of a woodland walk, such as:
Vomiting
Diarrhoea
Abdominal pain
Lethargy or tiredness
Muscle tremors or trembling
High body temperature
What to Do
Contact your vet immediately: if your dog shows these symptoms after a woodland walk, especially during the autumn months.
Treatment focuses on managing the symptoms and can include:
Intravenous (IV) fluid therapy
Antibiotics
Anti-sickness medication
Knowns and Unknowns
Seasonal:
SCI cases are most frequent between August and November.
Unknown Cause:
The exact cause is still unknown, but researchers have ruled out some factors like man-made poisons and algae.
Potential Culprit:
While not definitively proven, researchers have investigated harvest mites as a potential cause due to their presence in affected areas and their similarity to mites linked to other diseases, according to PetHelpful.
No Specific Test:
There is no specific test to diagnose SCI, so other conditions with similar symptoms need to be excluded by a veterinarian.
Prevention
Vigilance:
Be aware of the risk of SCI during woodland walks, especially in known hotspots like the Sandringham Estate in Norfolk and other areas in East Anglia, Nottinghamshire, and Lincolnshire.
Consider Protection:
Some veterinarians may recommend using a fipronil-based parasite treatment, as this has shown some effect on other mites, though it is not a licenced preventative for SCI in the UK.
Recovery
With prompt and appropriate treatment, the majority of dogs with SCI recover within about a week. However, early and swift action is vital due to the potential severity of the illness.
