dog vasectomy

With increasing interest in the benefits of dogs’ longer exposure to gonadal hormones and demand for options other than traditional spay/neuter, a study published in early 2023 caught my attention. It compares health and behavior outcomes for dog vasectomy and ovary-sparing spay patients with both sexually intact dogs and those with gonads surgically removed as is the current standard practice. It’s a small sample for dogs who’ve had those surgeries, but the results look interesting. I tried to include most of the important points. The full list of health conditions compared is long, but researchers grouped them as follows:

– Orthopedic problems, including blown knees
– Cancer
– Obesity
– Endocrine disorders (thyroid disease, diabetes)
– Reproductive disorders
– Other health problems (dental, heart, kidney, and eye diseases and disorders)
– Problematic behaviors (aggression, anxiety)
– Nuisance behaviors (mounting, marking)
