1) Preparing to Mate

Planning puppies? Follow our best practices.

Preparing to Mate is the first and, hopefully, the longest stage of your PUPLIFE pathway. Ideally, you’ll have discovered us before your female’s season begins, giving you time to follow best practices that prioritise her safety and set you up for success.

This stage encompasses everything from selecting stud dogs and conducting ovulation testing to understanding modern mating methods. We’ll help you take confident and well-informed steps that strengthen the gene pool and give your puppies the best start in life, keeping them healthy, happy and highly desired.

Ready for more personal support?

Preparing to Mate is one of the most crucial stages of the PUPLIFE pathway. If the tools, tips and advice on this page have answered your question, chances are they’ve also sparked a few more.

Turn Progesterone Numbers Into Clear Mating Decisions.

No more confusion around progesterone testing:

• 🧪 Different machines → Different numbers
• 🧪 Wrong unit → Wrong interpretation
• 🧪 Misread results → Missed mating window

The result?

​Mating too early. Mating too late. Or missing the cycle entirely and wondering what went wrong.

The Progesterone Ovulation Whelping Wizard removes the guesswork by instantly converting your test result across the two most common systems, so you can see exactly where your bitch is in her cycle.

This is your clarity tool for ovulation timing, helping you plan matings properly, ask better questions, and avoid costly timing mistakes.
​
Why Ovulation Testing Matters
✓ Identifies the true fertile window
✓ Improves conception rates and litter consistency
✓ Reduces unnecessary repeat matings
