Sterility in Dogs

Most dogs, if not neutered or spayed, are apt to produce too often and too many pups; however, there are those dogs who are sterile and can't reproduce even though their owners want them to.

  1. Males

    • Sterility in a male dog can be caused by azoospermia, which means that the amount of sperm produced is insufficient. This can be caused by previous infections. In addition, sometimes a male dog simply isn't attracted to the female dog.

    Mycoplasma

    • An organism called Mycoplasma can result in kennel-wide sterility, according to ShowdogsSupersite.com.

    Brucellosis in Females and Males

    • A disease of the reproductive tract called Brucellosis can cause sterility in both female and male dogs and cause a female to abort her pups, according to WildsideKennels.com.

    Other Causes

    • Sterility can be the result of inbreeding, trauma, drugs or toxins, hypothyroidism, hyperadrenocorticism (excessive production of adrenal hormones), environmental damage, heat stress, systemic disease, prostate disease, presence of a dominant pet guardian or female dog, inflammation, or infection or cancer of the reproductive tract.

    Discomfort

    • Incomplete ejaculation can occur because the stud is uncomfortable in the breeding situation, according to Rural Area Veterinary Services.
