Mycoplasmas in dogs are a family of many species of bacteria that are found in some healthy dogs, though they can cause serious infection and illness, too. These bacteria are the smallest known life form capable of reproducing, and many species are capable of living in host organisms without causing harm, but others are able to proliferate and cause diseases such as kennel cough and pneumonia. This is especially true in dogs that have compromised immune systems. Fortunately, most mycoplasma infections are treatable with antibiotics, but it is important to seek treatment as soon as possible, as infections can spread to other parts of the body and cause severe damage. If you see the signs of a mycoplasma infection in your dog, consult your veterinarian right away for a proper diagnosis and treatment. Here is what you should know about the symptoms, causes, and treatments for mycoplasma infection in dogs.

The symptoms of mycoplasma infection in dogs can vary depending on which species is responsible for the infection and where in the body the infection is located. Most healthy dogs’ immune systems are able to keep infections in check and fight off mycoplasma bacteria, so they may show no signs of an infection at all, even though they carry the bacteria. However, sometimes mycoplasma bacteria are able to proliferate and cause symptoms in dogs. Here are some of the symptoms seen in dogs that suffer from mycoplasma bacteria infection.

  • Sneezing and sniffling
  • Nasal discharge
  • Coughing
  • Pneumonia
  • Weakness
  • Lethargy
  • Loss of appetite
  • Weight loss
  • Bladder or urinary tract infection
  • Frequent urination or straining to urinate
  • Blood in the urine
  • Colitis
  • Diarrhea
  • Blood or mucus in stool
  • Conjunctivitis
  • Discharge from the eyes
  • Arthritis
  • Skin abscesses
  • Neurological problems
  • Anemia
  • Infertility
  • Abortion in pregnant dogs

Causes Of Mycoplasma Infection In Dogs

The causes of mycoplasma infection in dogs are a combination of exposure to the bacteria and overall health of the immune system. Exposure to mycoplasma bacteria can happen when dogs come into contact with other sick animals. This is fairly common in places where many dogs are together, such as dog parks, kennels, or shelters. The longer dogs spend with other animals, the greater their chances of being exposed to the bacteria. Dogs that mate with infected animals, receive a blood transfusion from infected animals, or fight and make contact with infected blood are more at risk.

Usually, healthy dogs’ immune systems are able to fight off infection, but when the immune system is compromised, dogs are more likely to be affected by mycoplasma bacteria. Another bacterial or viral infection can suppress the immune system, as can certain medical treatments like chemotherapy or immunosuppressant drugs. Any long-term or chronic disease may also reduce the immune system’s ability to fight off mycoplasma bacteria.

Treatment for mycoplasma infection in dogs relies on a certain type of antibiotics. Some antibiotics that attack the cell wall are not effective against mycoplasma, as this family of bacteria doesn’t have a cell wall. Tetracycline and doxycycline are often prescribed for mycoplasma infection, instead. These are usually prescribed for at least two weeks. If your dog suffers from a mycoplasma infection, it is important to continue treatment until a veterinarian advises you to stop, even if symptoms improve. Failing to do so will often result in a relapse that will be even more difficult to treat. Some mycoplasma infections can be transmitted to humans, so it is important that you take precautions when treating your dog.

In emergency cases, dogs may be treated with intravenous fluid and hospitalization. Some that suffer from anemia may need a blood transfusion, or they may need glucocorticoids. Usually, any medical treatment that suppresses the immune system will need to be halted until the infection clears up.
