What is brown dog tick?
Updated By PetymFacts checked against official sources on
Quick answer
The brown dog tick, Rhipicephalus sanguineus, is the most common tick on dogs in the tropics, including India. Unlike most ticks it lives and breeds indoors, in homes and kennels, as well as outdoors. It spreads ehrlichiosis and one form of babesiosis, the infections Indian owners call tick fever, so tick control is needed all year.
Also called Rhipicephalus sanguineus, kennel tick, dog tick, ticks on dogs.

How does the brown dog tick live?
It feeds on dogs at every stage and drops off between meals to moult or lay eggs, often inside the home.
Eggs
A fully fed female drops off the dog and lays about 4,000 eggs on average, in cracks and crevices in homes, garages and dog runs. University of Florida IFAS Extension
Larva
Larvae feed on a dog for 5 to 15 days, drop off, and take one to two weeks to become nymphs. University of Florida IFAS Extension
Nymph
Nymphs feed for 3 to 13 days, fall off, and take about two weeks to become adults. University of Florida IFAS Extension
Adult
Adults attach, often on the head and ears, between the toes, on the back and in the armpits. The whole cycle can happen indoors or outdoors, and more than once a year in warm climates. Parasites & Vectors (2010)study
Why is the brown dog tick a problem indoors?
Because it does not need grass or forest. A dog that never leaves a flat except for walks on concrete can still carry it home from a park, a groomer or a kennel, and then the tick can complete its whole life cycle inside. In a heavily infested home the ticks climb walls and hide in cracks at floor level, so treating the dog alone may not end the problem.
This matters for tick fever. Ehrlichiosis signs appear 1 to 3 weeks after infection, and babesiosis usually within 1 to 4 weeks, so a dog can fall ill after the tick that infected it is long gone.
How do you check a dog for ticks and control them?
Tropical guidelines say to use tick control all year, on indoor dogs too.
- Run your fingers over the dog daily, checking the ears, armpits, groin, around the eyes and between the toes. Tropical Council for Companion Animal Parasites
- Use a tick product licensed for the species, as the label says, and ask your vet which one suits; mention other pets at home. Tropical Council for Companion Animal Parasites
- Never use a dog's tick product on a cat without your vet's advice: some dog ingredients are toxic to cats. International Cat Care
- Remove an attached tick with fine-tipped tweezers close to the skin, pulling straight up without twisting or crushing. Merck Veterinary Manual
- Skip nail polish, petroleum jelly and hot matches; they can make the tick inject more saliva. Merck Veterinary Manual
- In a heavy infestation, treat the home or kennel too, paying attention to cracks and floor edges. University of Florida IFAS Extension

Questions owners ask
Can brown dog ticks live in my house?
- Yes. Unlike most ticks, the brown dog tick lives and breeds indoors. Fed females drop off the dog and lay eggs in cracks and crevices, and owners often first notice ticks crawling up walls or curtains. Treating the dog and the home together usually ends it.
Do brown dog ticks bite humans?
- They prefer dogs, and biting people is uncommon, but this species will bite humans. Remove a tick on a person with tweezers in the same way and wash the bite. The US CDC advises seeing a doctor if a rash or fever develops in the weeks after a tick bite.
Are ticks worse in the monsoon in India?
- Several Indian studies, in Chennai, Bhubaneswar and Tripura, found ticks on dogs most often in the monsoon months, but ticks were present all year. Studies of tick-borne infections disagree on the peak season, so keep tick prevention going twelve months a year.
Can my indoor dog get ticks?
- Yes. Tropical guidelines say indoor dogs meet ticks at parks and groomers, and the brown dog tick can then breed inside the home. Year-round tick control, regular checks and quick removal protect indoor dogs as much as outdoor ones.

- BabesiosisBabesiosis is a disease of dogs caused by Babesia, tiny parasites that live in and destroy red blood cells. It is spread mainly by ticks, and in India one species, Babesia gibsoni, also spreads through dog fights and blood transfusions. Signs are anaemia with pale gums, weakness, jaundice and red or brown urine. Dogs that recover can relapse.
- Booster vaccineA booster is a repeat dose of a vaccine that tops up or confirms a pet's protection. Puppies and kittens get a booster at about 26 weeks after their first course. After that, modern core vaccines for distemper, parvovirus and panleukopenia protect for years, while leptospirosis, kennel cough and most killed vaccines need a booster every year.
- Core vaccinesCore vaccines are the vaccines every dog or cat should have, wherever it lives, because they protect against widespread, serious diseases. For dogs they cover distemper, adenovirus and parvovirus; for cats, panleukopenia, herpesvirus and calicivirus. In India rabies is core for both, and WSAVA also treats leptospirosis vaccine as core for dogs where the disease is endemic.
- DewormingDeworming is giving a pet medicine, chosen by your vet, to kill intestinal worms such as roundworms, hookworms and tapeworms. Puppies can be born with roundworms and catch more from their mother's milk, so deworming starts in the first weeks of life. Some dog and cat worms can infect people, especially children, so regular deworming protects the family too.
- DHPPi vaccineDHPPi is the combined core vaccine for dogs printed on many Indian vaccine cards. The letters stand for distemper (D), hepatitis from canine adenovirus (H), parvovirus (P) and parainfluenza (Pi). DHPPiL adds leptospirosis (L). It is the same vaccine group that US cards call DHPP or DA2PP, and puppies start it at 6 to 8 weeks.
- EhrlichiosisEhrlichiosis is a disease of dogs caused by Ehrlichia canis, a bacterium carried by the brown dog tick. Signs appear 1 to 3 weeks after infection: fever, dullness, bleeding such as nosebleeds or bruising, and enlarged lymph nodes. Some dogs seem to recover but carry the infection silently and later develop a severe chronic form.
- Flea and tick preventionFlea and tick prevention means regularly protecting a pet from these parasites with a product your vet recommends, plus checking the coat and treating the home. Tropical guidelines say dogs and cats in places like India should be protected all year, including indoor pets. Use products licensed for the species, and never put a dog product on a cat.
- FleasFleas are small, wingless, blood-feeding insects. The cat flea, Ctenocephalides felis, is the most common flea on dogs and cats worldwide, and the main flea on dogs studied in India. Fleas cause itching, flea allergy, tapeworm and, in heavy infestations, anaemia in puppies and kittens. Most of the flea life cycle happens in the home.
- FVRCP vaccineFVRCP is the core combined vaccine for cats. It protects against feline viral rhinotracheitis (herpesvirus), calicivirus and panleukopenia. Indian cards often show a brand name from the vial sticker instead, such as Tricat. Kittens start at 6 to 8 weeks, with doses every 2 to 4 weeks until 16 weeks or older, then a booster at about 26 weeks.
- HeartwormHeartworm, Dirofilaria immitis, is a long worm that lives in the heart and lung blood vessels of dogs and, less often, cats. It is spread by mosquito bites and is widespread in tropical regions, including parts of India. Signs include coughing, tiring on exercise and weight loss. It can be prevented, and dogs should be tested yearly.
