Vets are warning dog owners to watch out for seasonal canine illness in Reading.

The condition affects dogs shortly after woodland walks between August and November and can be fatal.

Reading vets Oakley Veterinary Clinic and Beechwood Veterinary Centre have posted warnings on Facebook to watch out for symptoms.

Vomiting, muscle tremors and diarrhoea may occur in dogs of all ages, genders and breeds.

Dogs suffering from SCI tend to become ill within 24-72 hours of walking in the woods, but vets do not know what causes SCI despite ongoing research from groups like the Animal Health Trust.

They may have to be treated with intra-venous fluid therapy, antibiotics and anti-sickness drugs, but most will recover within a week of treatment.

Fortunately only a very small number of dogs die from the condition each year.

According to the Pet Healthy Club, research to-date has ruled out man-made poisons, contaminated water sources, fungi and natural flora as causes.

Mites have been suggested as a trigger but many dogs will pick up them up and never become unwell.

Should you suspect that your dog has SCI you should contact your vet immediately.

Preventative action: Blue Cross for Pets advises that dog owners take the following steps when taking their dog for a woodland walk.

Keep your dog hydrated Use preventative spray against mites before you walk your dog. Research suggests that harvest mites are commonly noted on dogs suffering with SCI.

Mention any woodland walks within the last few days to your vet if your pet requires attention.
