Desexing is commonly performed in dogs to prevent pregnancy and eliminate the risk of reproductive diseases. However, gonad removal prevents the feedback of estrogen and testosterone on the pituitary and hypothalamus. As a result, luteinizing hormone (LH) is continuously elevated at supraphysiologic concentrations. Constant activation of LH receptors in the skin, thyroid, adrenal glands, urinary bladder, lymphocytes, ligaments, etc. increases the dog’s lifetime risk for developing chronic disease and cancer. With more and more research coming out on the long-term health problems associated with gonad removal, dog owners and veterinarians are reconsidering at what age desexing should be performed if at all. This lecture will discuss the pros and cons of pediatric, pre-pubertal, and post-pubertal traditional desexing as well as the pros and cons of the surgical and medical alternatives.
