Macau's warm, humid climate lets ticks thrive in every season. Learn how ehrlichiosis, babesiosis and anaplasmosis spread, the warning signs, and how to keep your dog protected all year.
Most pet owners think of ticks as a problem for the countryside or the cooler months, but in Macau's subtropical climate the reality is different. Warm temperatures and high humidity allow ticks to remain active throughout the year, even in our densely built, high-rise neighbourhoods. The brown dog tick in particular can complete its entire life cycle indoors, which means an apartment, a stairwell or a shared garden can harbour these parasites long after a single infested dog has passed through. The danger is not the bite itself but the diseases ticks transmit: ehrlichiosis, babesiosis and anaplasmosis can quietly damage your pet's blood cells and organs for weeks before obvious illness appears. Understanding how these infections work is the first step to preventing them.
How ticks spread disease in our climate
A tick must stay attached and feed for many hours, often a day or more, before it transmits an infection, which is why prompt removal matters so much. In Macau, the brown dog tick (Rhipicephalus sanguineus) is the most common species and the principal carrier of canine ehrlichiosis and babesiosis. Because it tolerates indoor environments, your dog does not need to visit a hillside trail or country park to be exposed; a walk along a planted walkway, a visit to a grooming salon, or contact with another dog in a lift lobby can be enough. The constant warmth means there is no true off-season, so a single missed dose of preventive medication can leave a meaningful gap in protection.
Ehrlichiosis, babesiosis and anaplasmosis explained
These three diseases differ but share a quiet, dangerous course. Ehrlichiosis attacks white blood cells and platelets; early signs include fever, lethargy, loss of appetite and nosebleeds, and untreated cases can progress to severe, sometimes life-threatening anaemia and bleeding. Babesiosis destroys red blood cells directly, causing pale or yellow-tinged gums, dark urine, weakness and collapse. Anaplasmosis can cause fever, joint pain and lameness, or in another form affect platelets and clotting. A worrying feature shared by all three is a 'subclinical' phase: a pet may seem to recover while the infection persists silently, only to relapse months later. This is why early veterinary testing matters.
Recognising the warning signs
Watch for changes that are easy to dismiss as ordinary tiredness: reduced energy, a smaller appetite, reluctance to walk, or a pet that seems 'just not right'. More specific red flags include pale gums, unexplained bruising, nosebleeds, blood in the urine, swollen joints or recurring fevers. Because tick-borne illness can move from mild to critical quickly, do not wait if your dog becomes suddenly weak, collapses or has pale or yellow gums. Our team is available around the clock on our 24-hour emergency line, +853 6677 6611, and early blood tests can confirm a diagnosis before the disease advances.
Year-round prevention and safe tick removal
Because ticks are active every month here, prevention must be continuous, not seasonal. Modern options include monthly or three-monthly oral chews and long-acting spot-on treatments that kill ticks before they can transmit disease; we will help you choose the product best suited to your dog's weight, lifestyle and health. Combine medication with a daily hands-on check, running your fingers over the ears, neck, between the toes and under the legs after every walk. If you find an attached tick, use fine-tipped tweezers to grasp it as close to the skin as possible and pull straight out with steady pressure. Do not twist, crush or burn it, and never apply oils or alcohol, as these can make the tick release more infectious fluid. Clean the area and monitor your pet, and bring it to us if you are unsure or if redness develops.
Key Takeaways
- Macau's warmth and humidity mean ticks are active all year, including indoors and in high-rise buildings.

- Pale gums, nosebleeds, dark urine, lameness or recurring fever warrant prompt veterinary testing.
- Use year-round preventive medication and check your dog by hand after every walk.
- Remove ticks straight out with fine tweezers; call our 24-hour line +853 6677 6611 if your pet is suddenly unwell.
