Consider reading: Dog Skin Diseases with Pictures
Rickettsial diseases can be challenging to diagnose, requiring multiple tests or rounds of treatment before a definitive diagnosis can be determined. The symptoms of these diseases can be similar to those of other tick-borne illnesses, making accurate diagnosis crucial.
Some common Rickettsial diseases include Rocky Mountain Spotted Fever, Ehrlichiosis, and Canine Anaplasmosis. These diseases can be severe and even life-threatening if left untreated.
Here are some key facts about Rickettsial diseases:
- Rocky Mountain Spotted Fever is caused by Rickettsia rickettsii and can be transmitted by the American Dog and Rocky Mountain Wood ticks, but not by the Brown Dog tick.
- Ehrlichiosis is caused by Ehrlichia species of bacteria and can be transmitted by the Brown Dog tick.
- Canine Anaplasmosis is caused by Anaplasma phagocytophilum and can be transmitted by the Blacklegged tick.
It's essential to be aware of the risks of Rickettsial diseases and take steps to prevent tick bites, such as using tick repellents and performing regular tick checks on your dog. If you suspect your dog has a Rickettsial disease, consult with a veterinarian promptly for proper diagnosis and treatment.
Anaplasmosis
Anaplasmosis is a tick-borne disease caused by Anaplasma species of bacteria, specifically Anaplasma phagocytophilum and Anaplasma platys. Both forms of canine anaplasmosis are found throughout the United States and Canada.
Areas where canine anaplasmosis is more common include the northeastern, mid-Atlantic and north-central states, as well as California. Anaplasma platys, specifically, is more common in Gulf Coast and southwestern states.
Anaplasma phagocytophilum is transmitted by the deer tick and the western black-legged tick, which are the same ticks that transmit Lyme disease, increasing the risk of co-infection with multiple tick-borne diseases. Anaplasma platys is transmitted by the brown dog tick.
Symptoms of Anaplasma phagocytophilum include loss of appetite, lethargy, lameness, reluctance to move, and in some cases, neck pain or neurologic signs. Symptoms are often vague and nonspecific.
Symptoms of Anaplasma platys include bruising on the gums and belly, and spontaneous nosebleeds. These symptoms are associated with failure of blood clotting.
Here's a summary of the symptoms of Anaplasmosis in dogs:
- Lameness
- Lethargy
- Fever
- Diarrhea
- Vomiting
- Respiratory difficulty
Some dogs with Anaplasmosis may also experience cyclic thrombocytopenia, where their platelets are intermittently lowered.
Symptoms and Signs
Symptoms of brown dog tick diseases in dogs can be tricky to diagnose because they're often non-specific. Fever, joint pain, lethargy, decreased appetite, and enlarged lymph nodes are common signs.
Dogs infected with Lyme disease may never show symptoms, but when they do, they can include fever, joint inflammation, recurrent lameness, lethargy, loss of appetite, and swollen lymph nodes.
Here are some common symptoms of brown dog tick diseases in dogs:
- Fever
- Joint pain or inflammation
- Lethargy
- Decreased appetite
- Enlarged lymph nodes
- Neurological problems
- Kidney problems
- Vomiting and/or diarrhea
Some diseases, like Ehrlichia, can cause bleeding issues, bruising, and abnormal platelet counts, while others, like Babesia, can lead to anemia, weight loss, and low platelet counts.
Symptoms of Babesia
If you suspect your dog has Babesia, look out for these symptoms: Anemia, weight loss, fever, lethargy, enlarged lymph nodes, low platelet count, and red or brown urine. Babesia can cause these symptoms because it affects red blood cells, leading to anemia and pallor.
Dogs who recover from Babesia can become carriers and may be infected for the rest of their lives, even without symptoms. This is because the bacteria can remain dormant in their system.
Some common symptoms of Babesia include lack of activity, generalized weakness, vomiting, loss of appetite, and weight loss. Babesia is caused by Babesia species of bacteria, including Babesia gibsoni and Babesia vogeli.
Here are some common symptoms of Babesia:
- Lack of activity/lethargy
- Generalized weakness
- Vomiting
- Loss of appetite
- Weight loss
Symptoms of Hepatozoonosis
If you suspect your dog has hepatozoonosis, it's essential to know the symptoms to get them the right treatment. Dogs with hepatozoonosis may have waxing and waning illness, meaning their symptoms come and go.
Fever is a common symptom of hepatozoonosis, as well as muscle pain and lethargy. Decreased appetite and anemia are also possible signs of the disease. Enlarged lymph nodes can be a visible indicator of infection.
Here are some of the possible symptoms of hepatozoonosis:
- Fever
- Muscle pain
- Lethargy
- Decreased appetite
- Anemia
- Enlarged lymph nodes
It's worth noting that the symptoms of hepatozoonosis can be similar to other tick-borne diseases, making diagnosis a bit tricky.
Signs of Anaplasmosis
Symptoms of Anaplasmosis can be quite tricky to identify, as they're often vague and nonspecific. This is because the bacteria infect different parts of the body, causing a range of symptoms.
Fever is a common symptom of Anaplasmosis, as well as joint pain and lethargy. Some dogs may also experience lameness, reluctance to move, and loss of appetite. In severe cases, neurological problems can occur.
Here are some common symptoms of Anaplasmosis:
- Lameness
- Lethargy
- Fever
- Loss of appetite
- Neck pain or neurologic signs
In some cases, Anaplasmosis can cause bleeding disorders, such as bruising on the gums and belly, or spontaneous nosebleeds. These symptoms can be life-threatening if left untreated.
Symptoms of Anaplasmosis can vary depending on the type of bacteria causing the infection. For example, Anaplasma phagocytophilum can cause symptoms associated with inflammation, while Anaplasma platys can cause symptoms associated with failure of blood clotting.

These diseases are spread by ticks that dogs encounter near home or while on trips, and can be diagnosed in dogs across North America.
Some of the most common tick-borne diseases diagnosed in Memphis area dogs are seen in dogs that encounter ticks near home.
Tick-borne illnesses can be contracted by pets while on out-of-state camping trips with their owners.
Testing for Tick Bites
Testing for tick bites is crucial in diagnosing brown dog tick diseases. Diagnostic testing for tick-borne diseases in dogs typically involves one or more type of blood tests.
A point-of-care test that also includes a heartworm test can diagnose Lyme, Ehrlichia, and Anaplasma. This test is relatively inexpensive and can be run as part of annual routine preventive care.
Testing annually can catch sub-clinical infections in the early stages before signs of disease develop. Routine bloodwork can show nonspecific changes that may increase suspicion for some tick-borne diseases.
Some nonspecific changes include decreased platelets, red blood cells, or white blood cells, and increased kidney and/or liver values. These findings don’t give a definitive diagnosis, but when combined with clinical signs may point in the right direction and guide further testing.
Specialized blood tests can be sent out to a veterinary diagnostic lab for detection of some vector-borne diseases. These tests are typically slightly more expensive and take longer to get results, but are very accurate at detecting the disease.
Babesia may be diagnosed by looking at blood cells under a microscope. Sometimes these organisms are apparent, but sometimes they are more scarce and require review by a veterinary clinical pathologist to find them.
Treatment and Prevention
Treatment for brown dog tick diseases is usually effective, but it's essential to monitor your dog closely. Veterinarians often recommend treatment after a positive test, followed by regular check-ups and lab tests to ensure the disease is fully cleared.
Broad-spectrum antibiotics are typically prescribed to treat tick-borne illnesses in dogs. Your vet may also recommend probiotics to prevent gastrointestinal issues while your dog is on antibiotics.
Preventing tick-borne diseases in dogs is crucial, and year-round tick prevention medications are the number one defense. Speak to your vet to find the best parasite prevention medication for your pet based on where you live and your dog's lifestyle.
Regular inspections of your dog's skin for ticks, especially after spending time in areas where ticks are common, are a must. No tick prevention method is 100% effective, so diligence is always necessary.

Treating
If your dog tests positive for a tick-borne infection, treatment is usually effective, but the decision to treat an asymptomatic dog is a point of controversy among veterinarians.
Treatment typically involves broad-spectrum antibiotics, which can be given orally or through injections. Some veterinarians recommend giving probiotics to prevent gastrointestinal issues during treatment.
Doxycycline is a common antibiotic used to cover many tick-borne diseases, and treatment usually needs to be continued for several weeks or longer to fully clear the infection.
Regular blood work may be necessary to detect recurrences as early as possible, especially for recurring tick-borne conditions.
Veterinarians may recommend monitoring your pet for signs of illness with examinations and laboratory testing, even after they appear to have recovered.

Boosting Your Dog's Immune System
Ticks can transmit multiple organisms to your dog through a single bite, allowing them to work together and hijack your dog's immune system.
This coinfection can lead to recurring or chronic infections, making it essential to boost your dog's immune system.
Some tick-borne organisms are capable of helping each other survive inside your pet's body, causing a range of symptoms.
These symptoms can appear weeks after your dog has become infected, making early detection crucial.
Regular veterinary check-ups can help identify potential issues before they become severe.
Boosting your dog's immune system can be achieved through a combination of diet, exercise, and parasite control.
A healthy diet rich in essential nutrients can help support your dog's immune system, while regular exercise can help keep their immune system strong.
Preventing tick bites is key to preventing tick-borne diseases, so make sure to use preventative measures such as tick collars, sprays, and flea and tick medication.
Tick Infestation and Life Cycle
Ticks are notorious for their ability to infest dogs and transmit diseases, and understanding their life cycle is key to prevention.
Female brown dog ticks lay up to 5,000 eggs at a time, which can hatch into larvae in as little as 3 weeks.
The larvae, also known as seed ticks, feed on their host's blood for 5-7 days before dropping off to molt into nymphs.
Nymphs then feed on their host's blood for another 5-7 days before molting into adult ticks, which can live for up to 2 years without feeding.
Life Cycle
The life cycle of a tick is a complex process that involves several stages, starting from the egg stage.
Ticks lay their eggs in the fall, which can hatch into larvae in as little as 30 days.
The larvae, also known as seed ticks, feed on the blood of small mammals and birds to grow.
After feeding, they molt into nymphs, which are the second stage of a tick's life cycle.
Nymphs also feed on the blood of larger animals, including humans, and can transmit diseases.
Adult ticks emerge from the nymph stage and feed on the blood of larger animals, including humans.
Female adult ticks can lay up to 2,000 eggs at a time, which can hatch into larvae and start the cycle over.
The entire life cycle of a tick can take up to two years to complete.

Areas to Check for Ticks
When checking your dog for ticks, it's essential to examine the areas where they like to hide. Ticks often attach themselves to the skin in areas that are difficult to see or reach.
The CDC recommends looking for ticks in the following areas:
- In and around the ears
- Around the eyelids
- Under the collar
- Under the front legs
- Between the back legs
- Between the toes
- Around the tail
Remember, ticks can be found in these areas because they like to attach themselves in hard-to-reach spots.
Tick Species
There are several tick species that can transmit diseases to humans and pets. The most common tick species found in the United States is the American dog tick.
The brown dog tick, also known as Rhipicephalus sanguineus, is a major vector of diseases in the Americas.
This tick species is known to be highly adaptable and can thrive in a wide range of environments, from urban to rural areas.
Description and Identification
The brown dog tick is a common species found in Florida, and it's essential to know how to identify it.
Eggs of the brown dog tick are spherical and dark brown in color.
Larvae have three pairs of legs and a body size of approximately 0.54 mm in length and 0.39 mm in width.
Nymphs and adults have four pairs of legs and are reddish-brown in color with an elongated body shape.
Nymphs are smaller than adults, measuring 1.14 to 1.30 mm in length and 0.57 to 0.66 mm in width.
Adults are larger, measuring 2.28 to 3.18 mm in length and 1.11 to 1.68 mm in width.
The different stages of the brown dog tick, from larvae to adults, can be distinguished by their size, with each stage becoming progressively larger.
The scutum, a darkened shield-like feature, covers the entire dorsal surface in males, but only the anterior dorsal surface in females.
Males and females can be difficult to distinguish without magnification due to their lack of coloration, but males take only small blood meals while females take large meals.
Nymphs are primarily distinguishable from adults by size, but this is unreliable and should be confirmed by microscopic examination.
The brown dog tick is easily recognized in Florida by its color, body shape, and hexagonal basis capituli, a flat surface where the mouthparts are attached.
The hexagonal basis capituli is a particularly good identifying characteristic, as only one other tick species with this feature has ever been found in Florida.
Hosts
Dogs are the primary hosts for brown dog ticks in all stages, and they're required for a large tick population to establish itself in the home.
In the United States, brown dog ticks prefer to attach to certain areas of a dog's body, including the head, ears, back, between toes, and axilla.
Checking these preferred attachment sites on your pet is crucial when trying to prevent a tick infestation or manage one that's already established.
Each active stage of a tick must locate a host, and in a domestic environment, this often means feeding on the same dog if there's only one present.
Removing dogs is unlikely to completely eliminate a tick infestation, as the tick may simply find an alternative host, such as a human.
In the southeastern US, brown dog ticks have been reported to occasionally feed on rodents and deer, but most collections are from dogs and humans.
Immature ticks are more likely to be found on humans than adult ticks, so it's essential to check all household members for ticks.
Cats and other domestic animals are not preferred hosts, but ticks can still occasionally be found feeding on them.
Checking all animals in a household for ticks and removing attached ticks is a crucial step in managing a tick infestation.
Rhipicephalus Sanguineus
Rhipicephalus Sanguineus is the scientific name for the brown dog tick, a common species found worldwide.
These ticks are known for their reddish-brown color and oval-shaped bodies, typically 3-5 millimeters in length.
They are found on dogs, but also on other mammals and occasionally on humans.
Rhipicephalus Sanguineus is a one-host tick, meaning it needs to feed on a single host to complete its life cycle.
They are known to transmit diseases such as ehrlichiosis and babesiosis to dogs.
In the United States, Rhipicephalus Sanguineus is found in the southern and western regions.
Prevention is key, and using tick preventatives on dogs can help reduce the risk of infestation.
Distribution
The brown dog tick is found worldwide and is considered the most widespread tick species in the world. It's a global problem, and it's essential to be aware of its presence.
Brown dog ticks are more common in warmer climates. This makes sense, considering their ability to thrive in a variety of environments.
They are present throughout Florida, which is a region known for its warm and humid climate. If you live in Florida, you should be extra vigilant about tick prevention.
Brown dog ticks can be found on dogs, in kennels, and even in houses. They're not picky about where they live, and they can easily infest your home if you're not careful.
