Welcome to the Playbook, and thank you.

Your purchase is confirmed. Your receipt has been emailed and your access to the Playbook is ready below.

Your Playbook is ready to read.

Nine modules, about 20,000 words. Every module has a ๐ŸŸข Simple version (3โ€“5 minute read, plain language) and a ๐Ÿ”ต Full version (10โ€“18 minute read, with biology, research, and citations).

Recommended approach: read all nine Simple versions first (about 30 minutes total). That gives you the complete picture. Then come back to the Full versions of the modules that matter most for your specific dog.

Even if your big dog is healthy today, the actions that matter most work on a months-to-years timeline. The sooner you start, the more time compounds.

  2. Module 1 (Simple) โ€” Why Big Dogs Age Faster. IGF-1 explained with a "growth switch" analogy anyone can follow.
  3. Module 3 (Simple) โ€” Is My Dog a Candidate? Three-question decision tree that tells you which Loyal drug (if any) applies to your dog.
  4. Module 7 (Simple) โ€” Ten Things You Can Do Today. The highest-leverage module. Start with #1 (body condition score). The rest follows.
