These tick-borne diseases occur throughout Europe and are as close as Normandy. Affected dogs have a fever for up to a week and enlarged lymph nodes. They are often lethargic, appear stiff and lose appetite. Blood tests confirm their presence. Very early treatment with doxycycline is effective but when the disease has become chronic and bone marrow is suppressed antibiotic therapy must continue for months and the prognosis remains guarded. Use effective tick prevention if your dog or cat is going abroad.
