Doxycycline broad-spectrum antibiotics are given to multiple species of animals to treat Lyme disease, chlamydia, toxoplasmosis, urinary tract infections (UTIs), and other bacterial infections. Doxycycline pet medications come in either 100 mg tablets or capsules.

Doxycycline is an antibiotic that treats infections caused by susceptible bacteria. It is commonly used to fight infections transmitted by ticks. This medication treats Lyme disease, Rocky Mountain spotted fever, toxoplasmosis, leptospirosis, ehrlichiosis, salmon poisoning, chlamydia, and urinary tract infections (UTIs). Doxycycline may be administered to multiple species.

Benefits of Doxycycline:

  • Effective broad-spectrum antibiotic that treats a variety of infections
  • Fights diseases transmitted by ticks
  • Treats urinary tract infections (UTIs)
  • Useful in a number of species, including cats, dogs, and horses
  • Low-cost generic
  • Easy administration of oral tablets or capsules

Doxycycline is used in animals by prescription only. Not for use in humans. Do not administer to any animal to which it was not prescribed.

Review package directions and warnings before use.

The directions below represent a typical usage. Follow the specifications of your veterinarian's prescription.


  1. Give dogs 2 to 5 mg per pound of body weight every 12 to 24 hours.
  2. Give cats 2 mg per pound of body weight every 12 hours. Provide a moist treat after dosing.
  3. Give horses 5 to 10 mg per pound of body weight every 12 hours (use in horses is generally reserved for treatment of ehrlichiosis).
  4. Administer oral tablets or capsules directly from hand to mouth.
  5. Administer doses with or without food. However, do not give this medication with dairy products (unless your veterinarian has instructed you to do so), as they inhibit absorption of Doxycycline.
  6. Provide plenty of water to any animal being treated with this antibiotic.

Administer once or twice per day, as prescribed.

Do not stop giving Doxycycline before the completion of the prescribed regimen. Symptoms may disappear before the infection is fully treated.

Product Details:

Doxycycline inhibits the production of proteins necessary to the growth and reproduction of bacteria. Once the infection cannot continue to spread, the immune system is able to eliminate it. Doxycycline's broad-spectrum action works against a number of infections. Although it is not FDA-approved for use in animals, veterinary prescriptions are common.

Doxycycline requires a prescription.
