Companion Animal Welfare and Canine Reproductive Disease

Reproductive diseases in dogs including pyometra and mammary tumours cause significant welfare harm, with neutering providing major protective benefits.

Key Facts

Pyometra affects 25% of intact female dogs by age 10 and is life-threatening
Mammary tumour risk is reduced by 99.5% if bitches are neutered before first season
Prostatic disease and testicular tumours are significantly reduced by castration in males
Timing of neutering affects orthopaedic disease risk in large breeds - specialist advice needed
Responsible breeding decisions reduce heritable disease burden in offspring

Welfare Considerations

Reproductive diseases cause significant, preventable suffering. Neutering at appropriate ages, with breed-specific timing for large dogs, eliminates most reproductive welfare problems.

What You Can Do

Discuss optimal neutering timing with your vet for your breed
Spay bitches that will not be used for responsible breeding
Perform required health tests before breeding to reduce heritable disease
