Benign prostatic hyperplasia is almost universal in intact male dogs over five years of age. Neutering resolves the condition but timing decisions involve welfare trade-offs.
BPH illustrates the complexity of neutering welfare decisions. Intact male dogs almost inevitably develop prostatic enlargement causing discomfort and functional problems as they age. Neutering resolves this entirely but carries risks that vary by breed, size, and age. In giant breeds, early neutering before skeletal maturity increases the risk of cranial cruciate disease and certain sarcomas. The optimal welfare decision balances BPH prevention against joint and cancer risks, and is therefore breed-specific. Chemical castration via deslorelin implant offers temporary testosterone suppression to manage BPH without permanent surgical neutering — useful for owners wishing to delay or evaluate before committing to surgery.
