Looking for the expanded newsletter edition?


The expanded version of this week's issue, Is the smallest puppy or kitten really doomed?, is inside the Vault.

Your membership also gives you immediate access to every previous expanded newsletter edition, including:

  • Do you know her ovulation day?
  • What if calcium is not what she needs?
  • Why heavier mothers lose more newborns
  • The puppy or kitten that looks fine but is not

Each expanded newsletter edition goes beyond the email with the practical details, decision points, and actions you can apply in your breeding program.

A new expanded newsletter edition is added every Saturday, along with access to 50+ checklists, protocols, videos, and breeder resources already inside the Vault.

Where the Newsletter Goes Deeper
for Dog & Cat Breeders


Access every expanded edition of my weekly newsletter, with more science, context, and practical guidance than fits in the email, plus 50+ checklists, protocols, and video resources already inside the Vault.


Some Questions Need More Than One Email.


The newsletter gives you the key idea. But breeding questions are rarely simple enough to fit into a few paragraphs.
Important details, exceptions, and practical implications can get lost when a complex topic has to stay short.
It is easy to find an answer online. It is much harder to know what the science actually says, which details matter, and what it means for your breeding program.
That is what the expanded editions are for. They take the question from the newsletter and give you the context, nuance, and practical guidance to understand it more deeply.

What Keeps This Worth $20/Month?


The library keeps growing. A new expanded newsletter edition is added every Saturday, with occasional ebooks and other in-depth resources added when a topic deserves them. What is inside today is only the starting point.

It is reference material you can come back to. An edition that is not relevant to you today may become exactly what you need during a future breeding cycle, pregnancy, whelping, or litter.

You are not paying for one expanded article. Your membership unlocks the entire archive of expanded editions, plus the 50+ protocols, checklists, videos, and breeder resources already inside the Vault.

Two Ways to Access Everything


Choose monthly or annual access. Both give you the complete Vault: every expanded newsletter edition, 50+ existing breeder resources, and every new expanded edition added while you’re a member.


Monthly — $20/month: Full access to everything inside the Vault, with a new expanded newsletter edition added every Saturday. Cancel anytime.


Annual — $200/year: Get the same full access for an entire year and save the equivalent of two months.

❓ Frequently Asked Questions


Q: Who is this for?
A: Dog and cat breeders who want fast, reliable tools and protocols they can actually use — without wasting hours online.


Q: Is this only for experienced breeders?
A: Not at all. Whether it’s your first litter or your 50th, the Vault gives you clarity, structure, and proven best practices.


Q: Can I cancel anytime?
A: Absolutely. You're never locked in. Cancel your subscription at any time and your access will remain active until the end of your billing cycle.


Q: Are there videos inside?
A: Yes — including including video lectures on dog and cat reproduction.


Q: How is this different from Googling when I have a problem? A: Google gives you 10 different opinions. The Vault gives you ONE proven protocol from a reproductive specialist who's seen it thousands of times. Plus, everything is organized by breeding stage—you're not hunting through blog posts at 2am.


Q: Will this work for my breed? A: These are species-specific protocols (dog vs. cat), not breed-specific. The physiology is the same whether you're breeding Chihuahuas or Great Danes, Persians or Bengals. The protocols account for size/breed variations where it matters.


Q: I'm just starting out—is this too advanced? A: The opposite. Experienced breeders wish they'd had these protocols from Day 1. You're getting the roadmap that prevents expensive mistakes and saves you years of trial-and-error.


Q: What if I only breed dogs (or only breed cats)? A: Perfect—all content is clearly labeled [DOG] or [CAT] so you can instantly find what's relevant to your species. You'll never waste time sifting through content that doesn't apply to you.
