As a broad-spectrum antibiotic, it’s used to treat everything from respiratory and urinary tract infections to heartworm. It’s also effective against tick-borne diseases like Lyme disease and Ehrlichiosis.
of Ehrlichia canis infection in dogs found that doxycycline administered in tablet form once daily for 28 days cleared most dogs of infection. A separate study confirmed its efficacy in treating Ehrlichiosis but also showed that the infection can persist in clinically normal dogs, even after extensive treatment with doxycycline.
A 2018 Consensus Statement from the American College of Veterinary Internal Medicine (ACVIM) recommends using doxycycline as the first choice in most sick dogs with suspected Lyme disease. Not only is it easy to administer, but it’s also effective against co-infections and has anti-arthritic and anti‐inflammatory properties.
Doxycycline is also included in heartworm treatment protocols. The American Heartworm Society recommends the use of doxycycline as part of heartworm adulticide therapy. A 2018 study of the treatment of canine heartworm disease recommended a 10 mg/kg doxycycline dosage for treatment, but a reduced dosage of 5 mg/kg for dogs who suffer severe gastrointestinal side effects.
Finally, a retrospective study of 386 dogs who received doxycycline for the treatment of various infectious diseases showed that vomiting occurred in 18.3% of dogs, diarrhea in 7% of dogs, and anorexia in 2.5% of dogs.
