Chlamydia in dogs is a very dangerous disease


Chlamydia of dogs can occur latently (asymptomatic form), subclinical form. The duration of the incubation period may be different. In dogs with strong immunity, chlamydia most often occurs in latent form. The dog is a virus carrier, but characteristic clinical manifestations do not appear.

The intensity of the symptoms of chlamydia in dogs depends on the localization of chlamydia in the body, the general physical condition of the animals, and resistance of the body. Frequent stressful situations, adverse conditions for keeping dogs lead to the activation of chlamydial infection. Chlamydia in dogs can develop against the background of secondary infections and diseases.

Chlamydial infection is characterized by clinical polymorphism. The disease can occur in the form of:

After penetration into animals, chlamydia with blood flow spread to all organs and systems of the body, causing a number of physiological functional changes, local and generalized disorders.

With chlamydia, the organs of the respiratory, gastrointestinal tract, urinary system, organs of vision, and hearing are affected. Possible disturbances in the work of the cardiovascular, nervous system. With chlamydia in dogs, in some cases I diagnose chlamydial myocarditis.

If chlamydia is localized in the middle ear, suppurative otitis media is noted in dogs. In case of infection of the respiratory system, bronchopneumonia, infectious tracheobronchitis develops. With joint damage - arthritis, polyarthritis. If chlamydia is localized in the digestive tract, the disease is manifested by diarrhea, refusal to feed, and vomiting.

In pregnant dogs infected with chlamydia, spontaneous abortions, the birth of weakened, non-viable offspring, puppies with anatomical malformations are possible. With genital lesions in bitches, due to the development of the inflammatory process in the organs of the genitourinary system, abundant purulent discharge from the external genitalia, vaginitis, and endometritis are noted. Inflammatory exudate may have a white color, an unpleasant odor. Dogs have purulent balanoposthitis, urethritis, prostatitis, pyelonephritis, inflammation of the foreskin. Chlamydial infection often causes infertility in animals, both males and females.

After a chlamydial infection, if timely treatment of chlamydia in a dog was carried out, incorrect treatment methods and pharmacological preparations were selected, serious complications can occur: paresis, paralysis of limbs, limp, deafness, weakening or complete loss of visual function, iridocyclitis, meningoencephalitis, polyneuritis, keratoconi .

With severe chlamydia, small newborn puppies die in the first two to three days from the time of infection.

Infectious disease, chlamydia in dogs at the initial stage can manifest itself with a sharp increase in temperature to 40-41 degrees. The dog becomes lethargic, inactive, can refuse food, offered treats.

Typical clinical manifestations, symptoms of chlamydia in dogs:

purulent, profuse mucous discharge from the eyes, nose,

bright copious discharge from the genitals,

deterioration in general condition, decreased physical activity, reactions to external stimuli,

periodic catarrh of the upper respiratory tract, dyspnea attacks,

heart rhythm disturbance,

a change in dog behavior,

decreased appetite, refusal to feed.

Important! Dogs with chlamydia can become a source of human infection, since chlamydial infection most often occurs in an asymptomatic form.

At autopsy of animals infected with chlamydia, an increase in the liver, spleen, lesions of the pleura of the lungs (pleurisy), signs of pneumonia, and destructive damage to tissues of other internal organs are noted. Pathological changes are noticeable in the organs of the cardiovascular system.

In smears from the conjunctiva, there are elementary bodies, inclusion bodies of chlamydia parasites.

Diagnosis of chlamydia in dogs

To make the correct accurate diagnosis of chlamydial infection in veterinary clinics, a comprehensive diagnosis is carried out. Given the variety of pathological manifestations, clinical symptoms that may indicate the presence of other infections in the animal’s body, four-legged patients are required to be assigned differential diagnostics (PCR, ELISA, RIF, PIF, RSK method). They also carry out a number of laboratory tests, serological tests, take smear-prints from the conjunctiva for cultural studies, examine the vaginal secretion of bitches, discharge from the external genitalia, and take a smear of the mucous membrane of the prepuce bag from males.

When making a diagnosis, symptoms, history, epizootological situation in the region are taken into account.

Dog Chlamydia Treatment

Treatment of chlamydia in dogs should be prescribed, take place under the supervision of a treating veterinarian. The treatment regimen, effective drugs for treating chlamydia in dogs can be prescribed solely on the basis of diagnostic data.

Comprehensive treatment methods include etiotropic therapy, bio-immunocorrection. local symptomatic treatment. The purpose of treatment is to cleanse the dog’s body from chlamydia, eliminate clinical manifestations, normalize the work of affected organs and body systems. Treatment is also aimed at strengthening the immune defenses, increasing the body's resistance.

For the treatment of dogs with chlamydia infection, veterinarians prescribe tetracycline antibiotics (doxycycline, metacyclin, clarithromycin, azithromycin), broad-spectrum antibiotics, fluoroquinols (ciprofloxacin), macrolides. The dosage depends on the degree of infection, age, body weight, general condition of the sick animal. To eliminate clinical symptoms, symptomatic drugs are prescribed.

Owners should never self-medicate! It is important to consider that chlamydia requires serious and very long, properly selected treatment. Otherwise, you can only harm your pet, provoking the development of serious complications. The duration of the treatment course is 25-31 days.

Treatment of chlamydia of dogs with antibiotics, depending on the shape, condition of the animal, the manifestation of symptoms, can take place in three approaches. Moreover, the duration of one course is 7-10 days, after which a week break.

With chlamydial conjunctivitis, blepharitis, ophthalmic ointments are prescribed to eliminate symptoms and normalize visual function, eye drops that include erythromycin.

In genital forms of chlamydia, females are prescribed rinsing, douching with antibacterial solutions (2% boric acid solution).

For dogs with chlamydial infection, vitamin and mineral complexes, homeopathic preparations, and immunomodulators can be prescribed as additional therapy to enhance the body's resistance.

To normalize, restore normal flora during antibiotic therapy, dogs are required to be given hepatoprotectors that increase the detoxification function of the liver, normalize the work of the body, enzyme preparations - lactovit, liquid bifidum, essentiale forte, carlsil, as well as antihistamines (tavegil). If the animals are not given drugs to normalize the intestinal microflora, for the rest of their lives, the dogs will suffer from digestive upsets and chronic dysbiosis.

With chlamydial conjunctivitis, blepharitis, ophthalmic ointments are prescribed to eliminate symptoms and normalize visual function, which are placed in the conjunctival sac, eye drops that include erythromycin, tetracycline, dietramycin.

After completing the treatment course, the veterinarian prescribes a re-diagnosis for chlamydia.

Prevention of chlamydia in dogs

In order to prevent the development of chlamydial infections, breeders, dog owners should carefully monitor the condition of their pet. Particular attention should be paid to the diet, living conditions, maintain, increase the immunity of animals with vitamin and mineral supplements. Do not allow uncontrolled mating, contact with stray stray animals on walks.

To reduce the risk of chlamydia infection in a dog, it is equally important to conduct timely preventive vaccination, adhering to the schedule, deworming, and treat the dog from ecto and endoparasites in time. Monovaccines of domestic and foreign production (Chlamicon) have been developed against chlamydia. Watch out for dog hygiene.

When grouping dogs in enclosures, kennels, it is important not only to create favorable conditions for keeping, keep the dog houses clean, but also to carry out disinfection every few months, including bowls, ammunition, bedding.

Before the planned mating it will not be superfluous to conduct an examination of the dogs, take smears for the presence of chlamydia from the vagina of the female, preputial bag of the male.

Having noticed the first signs, symptoms of chlamydia in your dog, if the general condition worsens, contact a veterinary clinic, take your favorite dog for examination to the clinic. Remember, every day of procrastination can be worth the life of your dog!

Disease Description

Chlamydia is an infectious disease. Chlamydia intracellular parasites cause it in dogs. Many species are known, but the potential danger for dogs is Chlamydophila psittaci, Chlamydophila felis and Chlamydophila pneumonia.

Chlamydia, if we take into account precisely the disease, is not common among dogs and is extremely rare. But some dogs may be carriers - when tested, they will be positive for chlamydia, but most often there are no clinical symptoms.

This is due to the diversity of chlamydia species. Diagnostic tests allow you to determine the presence of chlamydia in the dog’s body, in principle, rather than their specific form.

Only three types of chlamydia cause clinical symptoms in dogs. Most often it is Chlamydophila psittaci (psittaci).

The clinical manifestation of the disease depends on the localization of this intracellular parasite in the body and on the specific type of pathogen.

The most common forms of manifestation are:

  • conjunctivitis,
  • damage to the respiratory system,
  • reproductive pathologies.

How does infection happen?

The methods of infection of a dog with chlamydia are also a controversial issue.

The widespread belief about sexual transmission of the disease is supported by only a few studies.

Infection with chlamydia psittaci occurs mainly from birds:

  • when eating poultry,
  • in contact with birds and their secretions.

From other animals, chlamydia is transmitted:

  • by contact
  • airborne (when sniffing, licking),
  • intrauterine - in pregnant females from mother to fetus,
  • sexually.

Chlamydia is not bacteria or viruses, they are intracellular parasites. They enter the environment with feces, various secretions, with aborted fruits.

In the external environment, they are quite resistant (even to some disinfectants). Once in a living cell, they quickly “settle down” in it, eating and multiplying.

All dogs can become infected, regardless of breed or age.

Even the place of residence does not play a big role. Both city and village doggies can get sick with the same probability.


It is not possible to completely protect the dog from this parasite, as it is found everywhere.

Especially Chlamydophila felis (chlamydia of cats), as it is very common among cats (about 40% of cats can get sick), which means it can be transmitted to dogs.

Chlamydophila psittaci is carried mainly by birds, in urban conditions it can be pigeons, from them, too, almost nowhere to hide.

Well, we should not forget about the sexual route of transmission of chlamydia, although it is not as common as contact and airborne droplets.

For prevention, we observe the following rules:

  1. On a walk, carefully monitor your pet. Keep him away from homeless cats.
  2. Make sure that the dog does not throw at the birds, and do not let him even sniff at any carrion.
  3. If your dog has a breeding value, carefully select a pair for it to be sure of the health of both dogs. But remember that the usual tests that are taken before viscous - do not provide reliable information. If the reaction to chlamydia is positive do not rush until you know the type of chlamydia. Most species do not bother our four-legged friends.
  4. Exclude self-walk.
  5. Immunity of a pet should always be strong, for this you need high-quality feeding, caring for the animal and the presence of the necessary vaccinations and treatments from external and internal parasites.

Briefly about the main thing

  1. Dog chlamydia is an infectious pathology caused by intracellular parasites of the genus Chlamydophila.
  2. The greatest danger to the health of dogs is only some types of chlamydia, but such pathologies are rare. More often you can meet a dog infected with cat chlamydia, it does not threaten the life of the pet, but causes problems with the eyes and respiratory organs, which is manifested more often by conjunctivitis and rhinitis.
  3. If the dog is infected with a highly pathogenic type of parasite, then the symptoms can be very dangerous: discharge from the eyes and nose, discharge from the genitals, further infertility is possible. In pregnant females, the disease manifests itself in severe abortions. If no measures are taken, death is possible.
  4. Infection occurs mainly by contact and airborne droplets, sexual transmission is possible. The carriers are cats, birds, other dogs, rodents. And Chlamydophila pneumonia is even carried by humans.
  5. Diagnosis is a difficult question. The only reliable method is serological reactions to determine the type of chlamydia. Other methods that determine the presence of antibodies in the dog’s body in general to the genus Chlamydophila do not have a diagnostic meaning.
  6. To prevent this trouble - strengthen the pet's immunity and carefully monitor it while walking.
