Furthermore she would likely transmit the disease to any male which breeds her causing fertility problems in him as well. Testing Testing for Brucellosis usually requires a blood test by your veterinarian and all positives should be retested for a confirmation. Since Brucella canis is mainly spread by the act of breeding, it is paramount to test all canines, male and female, prior to breeding. Test between every breeding of different animals. In the case of a male, if he serviced a female since his last test, then he must be tested again even if his last test was as recent as four weeks ago.
Testing is the only sure way to detect carriers.
In cases of abortion, the bacteria may be isolated from the aborted fetuses. Blood tests can also be performed on the mother's blood to help confirm a positive diagnosis of Brucellosis. When possible, all incoming breeding dogs should be isolated for two weeks upon arrival at the kennel. Do this even if the dog was tested before shipment. This may seem excessive but you will spend a lot more money if Brucellosis creeps into your kennel, not to mention the disruption in your breeding program and loss of genetic potential.
