Similar to humans, our canine companions are vulnerable to infections caused by bacteria and are vulnerable to these types of infections. Dogs are sometimes treated for bacterial infections with the same medications that treat bacterial infections in humans, such as the prescription medication doxycycline.

However, dosages vary widely between humans and canines. So if you’re wondering, “can I give my dog doxycycline?” The answer is, only if your vet has prescribed it. Here’s what to know about treating your dog with doxycycline for an infection.

Why Dogs May Be Prescribed Doxycycline

Doxycycline is a medication known as a tetracycline antibiotic. It is used to treat bacterial infections in dogs. In some cases, it may also be used to prevent a secondary infection from developing, in dogs who have tested positive for viral infections such as parvovirus. Dogs may be prescribed doxycycline to treat:

  • Ehrlichiosis
  • Heartworm disease
  • Infected wounds
  • Leptospirosis
  • Lyme Disease
  • Periodontal disease (gum disease)
  • Respiratory infections
  • Rocky Mountain Spotted Fever
  • Urinary tract infections

Common Reasons Vets Prescribe Doxycycline

Doxycycline, which is generic for the brand drug Acticlate is a commonly prescribed antibiotic in veterinary medicine. It is prescribed by vets to treat bacterial infections and prevent secondary bacterial infections stemming from a viral infection.

Ehrlichiosis

Ehrlichiosis is a bacterial infection caused by the Ehrlichia bacteria. Dogs may become infected with Ehrlichia as the result of a tick bite. Dogs who develop ehrlichiosis may exhibit symptoms such as fever, lethargy, poor appetite, vomiting, and diarrhea. Veterinarians may prescribe doxycycline to treat ehrlichiosis.

Heartworm Disease

Heartworm disease can be fatal to dogs. It causes damage to the lungs, heart, and other organs. It is caused by a parasitic worm that infects dogs through a mosquito bite. Symptoms of heartworm disease may not appear for some time as the disease can progress slowly. When symptoms do appear they may include cough, tiredness, and difficulty breathing. Veterinarians may prescribe doxycycline as part of a regimen to treat heartworm disease in dogs.

Infected Wounds

If your dog sustains a laceration or other wound, it may become infected if not treated properly. You should schedule an appointment with your veterinarian, to ensure that the area is properly cleaned. If an infection does result from a wound, your veterinarian may prescribe doxycycline.

Leptospirosis

Leptospirosis is a bacterial infection caused by Leptospira bacteria. Leptospira bacteria are found in soil and water. Dogs can develop leptospirosis from drinking water from a lake, stream, or river. Exposure to farm animals or other infected wildlife may also lead to infection. Veterinarians may prescribe doxycycline to treat leptospirosis.

Lyme Disease

Dogs bitten by ticks are at risk of developing Lyme Disease. Lyme Disease results from the bacteria Borrelia burgdorferi, and it is transmitted by deer ticks. Symptoms of Lyme Disease in pets may include fever, loss of appetite, swelling of the joints, and lethargy. Veterinarians may prescribe doxycycline to treat Lyme Disease in dogs.

Periodontal Disease

Periodontal disease is very common in dogs. It is caused by bacteria in the mouth. The bacteria causes damage to the gums, bone, and teeth. Symptoms of periodontal disease in dogs may include red, swollen gums, bad breath, bleeding gums, and tooth loss. Doxycycline may be prescribed to assist in the treatment of periodontal disease in dogs.

Respiratory Infections

Dogs can develop bacterial pneumonia, just as humans can develop this condition. A variety of bacteria may lead to inflammation and infection of the lungs. Respiratory infections in dogs may also develop as a secondary infection following a viral infection such as influenza, adenovirus, or parainfluenza. Doxycycline may be prescribed to your dog to treat a respiratory infection.

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever is a bacterial infection transmitted by infected ticks. Despite its name, this type of bacterial infection which affects both humans and dogs is frequently found in North Carolina, Tennessee, Missouri, Arkansas, and Oklahoma. Doxycycline may be prescribed to treat Rocky Mountain Spotted Fever.

Urinary Tract Infections

Bacterial urinary tract infections (UTIs) are the most common infections veterinarians treat in dogs. According to the American Kennel Club, 14% of dogs will be infected with a bacterial UTI at some point in their lives. Symptoms may include frequent urination, blood in the urine, cloudy urine, straining, or crying while urinating. Doxycycline may be prescribed if your dog is diagnosed with a UTI.

Side Effects of Doxycycline in Pets

All medications have the potential to cause side effects in pets. Doxycycline is typically well tolerated by most dogs. However, some dogs may experience side effects of doxycycline including:

  • Diarrhea
  • Vomiting
  • Lack of appetite

Most side effects will resolve on their own. To be safe, notify your vet if your dog is experiencing any side effects of doxycycline.
