The latest science and recommendations on timing breedings, made simple.

This is a clear and plain-English guide to ovulation timing for dog breeders. The easy-to-follow graphics and animations makes learning easy and make a (seemingly) complicated subject easy to understand.

With so much conflicting advice available, it's no surprise that determining the best time to breed can be confusing. That's why I carefully reviewed the research, evaluated the evidence, and combined those findings with nearly 30 years of experience in successfully timing breedings.

The result is a practical, breeder-focused guide that translates the best available science into clear, actionable recommendations you can use with confidence.
