The Poodle Genetics Book Series: What's Actually in Each Volume

Three Books, Not One

Most poodle genetics content online is a single article or a single locus. It answers one question and stops. The Poodle Genetics Lab book series exists because breeding decisions rarely stop at one question: a single litter can raise a color question, a merle-risk question, and a hip-screening question all at once, and a 1,500-word article was never going to hold all three.

So the series is three volumes instead of one book, split by subject rather than by difficulty: Volume I covers coat color inheritance, Volume II covers merle and dilution genetics specifically, and Volume III covers inherited health and structure. Each is referenced against the current peer-reviewed literature and can be read on its own — you don't need Volume I to understand Volume III.

Volume I: Poodle Color Genetics

348 pages · Second Edition · $44.99 PDF / $54.99 paperback

This is the flagship reference: the most comprehensive single book on poodle coat color inheritance available, covering the E, K, A, B, D, S, M, G, I, and R loci with reference plates and inheritance tables throughout. The ten chapters move from foundational genetics through each locus in turn, then close with a chapter on interpreting DNA test results and building an actual breeding plan around them, plus a full reference-chart and color-gallery appendix.

If you've read our E locus article or the B locus piece on brown, Volume I is that same depth of treatment applied to every color locus in one place, not scattered across a dozen separate reads. It has its own dedicated page with a full table of contents if you want to see exactly what's inside before buying.

Volume II: Advanced Poodle Genetics — Merle and Dilution

301 pages · $44.99 PDF / $54.99 paperback

Volume II exists because merle deserves more than a chapter. It's the complete science of the M locus: the seven-allele merle classification system, the six-tier merle risk framework and pairing matrix, how to interpret a DNA report that comes back mosaic, and why white coverage is not a reliable predictor of how "loud" a merle actually is. A full section covers dilution genetics separately, including the d1/d2/d3 compound-heterozygosity model behind true blue and lilac, how to tell those apart from the G-locus greying route that produces look-alike silver and café-au-lait coats, and an honest look at the current evidence limits around color dilution alopecia.

It also does something most merle content won't: it addresses merle's disputed, still-unresolved origin in poodles directly, rather than repeating an assumed history as settled fact.

If you're breeding merles, or breeding anything that could produce one, this is the volume that matters most — see our merle article for a preview of the reasoning, or run a pairing through the merle calculator directly.

Volume III: Poodle Health & Structural Genetics

491 pages · $44.99 PDF / $54.99 paperback

The largest volume in the series, and the one most breeders eventually need. It opens with a molecular genetics primer and a chapter on reading inheritance patterns through actual poodle pedigrees, then moves into skeletal structure and growth across all three poodle sizes — proportion, angulation, movement, growth-plate timing, and where structural faults genuinely trace back to genetics versus development or environment.

The bulk of the book is inherited disease, referenced against the current literature with the same rigor as Volume I: hip and elbow dysplasia, progressive retinal atrophy, degenerative myelopathy, von Willebrand disease, Addison's disease, sebaceous adenitis, cancer risk, and longevity. One chapter addresses behavior genetics specifically, and the closing chapters cover reproductive genetics and work through evidence-based breeding case studies end to end.

If your program screens for structural soundness and inherited disease alongside color, this is the reference for that work — see our piece on CDDY and IVDD risk for a sample of the kind of health-genetics reasoning the full volume covers in depth.

Which Volume Do You Actually Need?

• You only care about coat color outcomes: start with Volume I. It stands alone.
• You're breeding, or considering breeding, a merle or dilute: Volume II isn't optional. Double-merle risk is not something to learn after the fact.
• You're running a breeding program that screens for health and structure: Volume III is the one that will get the most use, and it doesn't require the other two first.
• You're building a serious, multi-generation breeding program: most breeders who buy one volume come back for the other two within a year. The complete series is priced for that.

Which Volume Should You Read First?

The section above sorts by subject. This one sorts by where you actually are right now, if you own none of the three yet and need to pick a starting point.

None of this locks you in. Each volume stands alone regardless of which one you buy first — the table above is about urgency, not sequence. A merle pairing on the calendar next month outranks a color question that can wait, even though Volume I is numbered first.

Buying the Series

Each volume is sold individually as a $44.99 PDF or a $54.99 Amazon paperback. The Complete Poodle Genetics Series bundles all three PDFs for $99 — a $35.97 saving over buying them one at a time — though the bundle is PDF-only; there's no combined paperback edition. All three are available from the shop.

How the Series Fits With PGL's Other Tools

The books, the calculator, and the DNA Interpreter teach the same underlying genetics in three different formats. The color calculator and merle calculator model the exact crosses the books explain, so you can test a pairing while you read. The DNA Interpreter applies the same reasoning to a real lab report, notation and all. And if you'd rather work through the material as a structured course with assessments and a certificate at the end instead of reading straight through, the PGL Genetics Academy covers much of the same ground in that format.

Common Questions

Do I need to read them in order? No. Each volume is written to stand alone. Most readers start with whichever subject their current breeding question is actually about.

Are these written for breeders, or for pet owners too? The series is written for breeders — the depth and the breeding-decision framing assume that context. Owners who want the genetics behind their own dog's coat without the breeding-program angle are usually better served by the Owner's Guide or the free genetics guide articles.

PDF or paperback — what's the actual difference? Same content. The PDF is instant and searchable; the paperback is a physical reference copy. The complete-series bundle is PDF-only.

How current is the science? Each volume is referenced against the current peer-reviewed literature at time of writing, the same standard applied across every PGL resource. Genetics research moves, and a book is a snapshot rather than a live feed — where the field has moved since publication, our free articles and tools are where that gets tracked.

The Bottom Line

The series is split by subject, not by skill level, because that's how real breeding decisions actually come up: a color question, a merle question, and a health question rarely arrive one at a time. Read the volume that answers what you're actually deciding right now, and add the other two when the next question does.
