Obesity remains preventable, and understanding these factors can improve our awareness of the risks. It is well established that obesity increases the peril of many other health problems including orthopedic disease, metabolic disorders and cancer. Orthopedic Disease Correlation: The second question
evaluated was the association between orthopedic disease (specifically non-traumatic cruciate ligament disease and arthri- tis) and reproductive status. Again, there is some conflicting data from other studies. In this breed, there appears to be a clear increase in orthopedic disease associated with “early” spay/neuter, which was defined as gonadectomy under the age of six months. This risk seems to decrease the later in age the gonadectomy is performed, presumably due to the positive impact of sex hormones on tendons, ligaments and bony growth plates. In other studies, it appears these correlations are found in large breed dogs specifically (not just Goldens). Smaller dogs do not appear to be affected like their larger counterparts. Caveats regarding these specific study findings: Only
one breed is included in this study cohort — purebred Golden Retrievers. As a group, this cohort has a higher standard of health care than average. There may be adjustments in the findings statistically as more data is collected as this population of dogs ages. Many of the dogs are just entering their middle years now. There are no simple or easy answers to these questions
because there are so many factors that influence biology and health. The goal of the GRLS is to help clarify what factors influence the health and welfare of our dogs, including genetics.
While the information about obesity and orthopedic disease is helpful, this study did not look at any of the potential negative outcomes that can be associated with pets not being spayed or neutered.
Examples include mammary (breast) cancer, ovarian and
testicular cancer, uterine infections, prostate disease and accidental litters. The decision to spay/neuter or what age to do so needs to be made based on all known health and environ- mental factors impacting the individual pet. The data so far suggests there are potential advantages to
delaying gonadectomy, or leaving large breed dogs intact if that is a practical option, but the potential negatives do need to be examined also. This is a conversation that should be had with your
veterinarian before deciding what is the best decision for your individual pet so you can explore all the pros and cons based on the information we have to date. One thing is certain, more data will continue to come from
this and other studies, and hopefully, these will illuminate the most healthful options we may elect for our beloved pets.
