Brown Dog Tick
(Rhipicephalus sanguineus Latreille)

This tick can complete its entire life cycle indoors.
It can establish populations in colder climates
and has been found in much of the world.
Many tick species can be carried indoors on animals,
but cannot complete their entire life cycle inside.
It will feed on a wide variety of mammals,
dogs are the preferred host in the U.S.

How It Starts
Ticks are brought into the house or kennel,
often on a dog which has been away outside.
The early stages of the infestation are often missed completely.
The first indication the dog owner has that there is a infestation
is they start noticing ticks around the house.
In the U.S., the brown dog tick prefers to feed on dogs in all stages.
However, it will feed on other mammals, including domestic animals and humans.
This is most likely to occur if it cannot find a dog nearby,
so beware of trying to control the tick by removing the dogs!
Elsewhere in the world, it is more frequently found feeding on other mammals.
This difference in host preference is not completely understood,
but is probably related to the animals available and differences
in the populations from the original introductions into new areas.
In the southeastern U.S., it has been reported occasionally from rodents and deer,
but most collections are from dogs and (much less commonly) humans.

Life Cycle
Ixodid ticks require three blood meals to complete development;
The brown dog tick is a 3-host tick;
It leaves the host to develop
between the larval, nymphal and adult stage.
Each stage must locate a host;
in a domestic environment this may result in feeding on the same animal
(if there is only one or a few dogs present),
A  female brown dog tick can lay up to 5000 eggs
The length of time for each stage,
and the time required for development to adulthood,
is dependent on temperature.
These ticks are tolerant of a wide range in conditions.
An adult female will feed on the host for about one week,
then drop off and find a secluded place for egg laying.
Cracks and crevices ETC.
This process can last as long as 15 days.
After she finishes laying her eggs, she dies.
The larvae hatch two to five weeks later, and look for a host.
All stages of this tick prefer dogs,
although they will feed on other animals.
Larvae take about two weeks to develop into nymphs.
The nymphs then feed for five to 10 days
and again take about two weeks to develop into adults.
As adults, both males and females will attach to hosts and feed,
although the males only feed for short periods.
The overall cycle can be completed in just over two months,
but frequently will take longer if there are few hosts available or cold temperatures.
Ticks are notoriously long-lived, and can live as long as
three to five months in each stage without feeding.
In warm climates, the cycle can occur year-round
both inside houses and in outside kennels and dog runs.

Dangers Of Ticks
Tick's can cause skin irritation and damage in dogs,
In the U.S., R. sanguineus is a vector of disease in dogs;
canine ehrlichiosis (Ehrlichia canis) and canine babesia (Babesia canis).

Proper parasite management is essential in preventing an infestation
or your dog becoming infected with a Tick pathogen.
These include preventative insecticides in the yard and tick control measures on your dog,
especially if they are a outside animal or field dog.
Repellent products are available both over the counter
and from your Veterinarian to utilize directly on your dog.

Human Animals and Brown Dog Ticks

Q fever is found around the world.
It is an infection which can cause pneumonia and hepatitis (liver inflammation) in its early stage,
and infection of the heart valves (endocarditis) in its chronic stage.
