Brucellosis in Dogs: The Breeding Kennel Disease Every Owner Should Know

In this guide

Canine brucellosis is a bacterial infection that spreads primarily through breeding, and it carries real weight for anyone running a home breeding setup or considering buying a puppy in India, where informal and small scale breeding is common.

How it spreads

Brucella canis spreads mainly through mating, but also through contact with an infected dog's vaginal discharge, semen, urine, or aborted foetal tissue. Puppies can also acquire it from an infected mother during pregnancy or nursing.

Signs in adult dogs

• In females: repeated late term abortion, usually around six to eight weeks into pregnancy, and infertility
• In males: swollen, inflamed testicles (epididymitis), and eventual infertility or testicular shrinkage
• General signs in both sexes: enlarged lymph nodes, mild lethargy, and in some cases spinal disc infection causing back pain
• Many infected dogs show no obvious symptoms at all, which makes it easy to miss

Why testing matters

Because brucellosis can spread silently and cause repeated reproductive failure, any breeding dog, male or female, should be tested before mating, and again periodically if used regularly for breeding. This is especially relevant in India, where organised pre breeding health screening is far less standard practice than it should be.

Treatment and an important caution

Brucellosis is difficult to cure completely with antibiotics, and infected dogs typically need to be removed from any breeding programme permanently, since the risk of ongoing transmission is too high. It is also a zoonotic disease, meaning it can spread to people, though human infection is uncommon and usually linked to close contact with infected reproductive tissue or fluid. Pregnant women and immunocompromised individuals should be especially cautious around a confirmed positive dog. Given both the reproductive and public health stakes, this is a condition where prevention through testing is far more effective than treatment after the fact.

Common Questions

Q: Does neutering reduce the risk of brucellosis? A: Yes, spaying or neutering removes the ability to transmit the infection through mating entirely, which is one reason it is recommended for any dog not actively used for breeding.

Q: Is brucellosis curable? A: It is difficult to fully clear with antibiotics, which is exactly why infected dogs are generally retired from breeding permanently rather than treated and returned to a breeding programme.
