Did you know that a single tick bite can put your dog's life at risk?
Biliary, or tick fever as most people know it, is one of the most common and most dangerous tick-borne diseases we treat at George Animal Hospital. It is caused by a tiny parasite called Babesia that gets injected into the bloodstream when a tick feeds. Once inside, it destroys red blood cells, which leaves your dog severely anaemic, weak, and in many cases fighting for their life.
The warning signs are easy to miss in the early stages.
A dog that suddenly seems tired or off their food.
Pale gums instead of healthy pink.
Dark or brownish urine.
A high fever.
Yellowing of the eyes or skin in advanced cases.
By the time these symptoms are obvious, your dog needs urgent veterinary care, often including a blood transfusion. And here on the Garden Route, with our warm and humid climate, ticks are active for most of the year, not just summer.
The good news is that biliary is highly preventable. A consistent tick prevention plan, regular tick checks after walks in the bush or on the beach, and an annual veterinary check-up can save your dog's life long before a tick ever gets the chance.
If your pet is not currently on a tick prevention programme, let's get them sorted.
