Neutering Dogs: Benefits, Risks, and When to Do It

Neutering is one of the most common procedures in veterinary practice — but timing matters.

Benefits

• Eliminates testicular cancer risk in males
• Dramatically reduces pyometra risk in females
• Prevents mammary tumours if done before second season
• Prevents unwanted litters

Risks and Considerations

• Increased orthopaedic risk in large breeds if neutered too early
• Weight gain post-procedure
• Possible urinary incontinence in some females

Timing

Traditional advice: 6 months. Current evidence suggests large breeds may benefit from waiting until physical maturity (12-18 months) before neutering.
