Most pets reach sexual maturity between 6 months (small breeds/cats) and 12 months (giant breeds). Gone are the days of blanket advice to neuter all pets at 6 months—though this remains sound advice in cases where pregnancy is a risk and in welfare situations.

At Hayfields Vet, we recommend spaying and castrating, as it significantly reduces life-threatening conditions like:
• Uterine infections (pyometra)
• Mammary cancer
• Prostatic disease
Sterilizing very young large and giant breed dogs may increase risks for:
• Joint disease
• Urinary incontinence
• Nonreproductive cancers

In our opinion, allowing dogs to reach musculoskeletal maturity (fully grown with a functional urethral sphincter) before neutering is ideal. Factors like breed type and temperament should also be considered.

Factors like breed type and temperament should also be considered.

Suggested Age for Neutering:
• Cats: Generally, at 6 months, though early neutering is possible in some cases.
• Dogs: Small breeds around 6-9 months; large and giant breeds after reaching musculoskeletal maturity (often 12-18 months).
