TICK FEVER
One of the greatest health hazards in Hong Kong for your dog!
Hong Kong has an abundance of the tick Rhipicephalus sanguineus more commonly referred to as the Brown Dog Tick. Their saliva carries three types of blood parasites namely Babesia canis, Babesia gibsoni both protozoans and Ehrlichia canis, a rickettsia which cause Tick Fever.
Often the first sign noticed is that your dog feels tired and starts to go off food. As the disease develops they may become progressively weaker, may have dark coloured or blood tinged urine, bleeding from the mucus membranes, and episodes of fever, vomiting and diarrhoea. The disease can have a very gradual onset and progression, with your best friend initially just looking “off colour” until the later stages when walking may not even be possible!
Treatment of Tick Fever is a combination of supportive measures and medication to kill the blood parasites. Treatment is generally very successful but some dogs can develop complications and in some dogs, despite aggressive treatment, it can still be fatal.
Remember these ticks seem to be everywhere in Hong Kong, some even associated with indoor plants!! Ticks will be part of of your dog’s life in Hong Kong, so you must learn to live around them!
The obvious way to avoid tick fever is to avoid ticks!
There are several “Anti-Tick” medications available ranging from monthly spot ons, three monthly tablets, 8 monthly collars and yearly injections!
Remember Tick Fever is a problem all year round- not just in summer!
Don’t neglect tick prevention – as always prevention is much better than treatment!
