Major veterinary bodies lean toward neutering before first heat, with a common window around five to six months, while shelters practice earlier pediatric procedures.
Health benefits include eliminating pyometra and testicular tumor risk and sharply reducing mammary tumors, with fewer heat yowls, roaming, and spraying behaviors.
Debate centers on very early neutering and skeletal development, with slight differences by breed and size, so the vet sets timing per individual.
Metabolism drops after neutering, so cut calories and weigh regularly to avoid obesity, and never skip pre-op exams and anesthesia assessment.
