BREEDR - Dog Breeding Genealogy Management System

A reactive, interactive dog breeding genealogy mapping system for professional kennel management.

---

🌟 Recent Highlights (v0.8.1 — July 2026)

• ✅ Fresh-install fix — Schema definitions reconciled with the routes; a brand-new database now boots with heat cycles, litters, and puppy logs fully working.
• ✅ Health Records overhaul — Per-type record forms (OFA / vaccination / exam / surgery / medication), document upload (PDF/image), OFA age validation, and delete actions.
• ✅ UX layer — Toast notifications, proper confirmation dialogs, load-error banners with retry, a 404 page, and mobile-friendly layouts across all pages.
• ✅ Hardened API — Sire/dam sex validation, transactional writes, and safe photo handling.

🚀 Quick Start

1. Docker Deployment (Recommended)

git clone https://git.alwisp.com/jason/breedr.git
cd breedr
docker-compose up -d --build

Access at: http://localhost:3000

2. Manual Development Setup

Requires Node.js 18+ (better-sqlite3 v11 ships prebuilds for Node 18–24).

npm install
cd client && npm install && cd ..
npm run dev        # runs API (nodemon, :3000) + client (vite, :5173) together

Note: The database initializes automatically on first boot — tables and columns are created/added via safe guards. No manual migrations are required.

🐕 Managing Your Kennel

• Adding Dogs: Go to the Dogs page, click Add New Dog. You can mark dogs as External if they aren't in your kennel but are needed for pedigree mapping.
• Champion Tracking: Toggle the Champion status to title dogs. Offspring will automatically display the "Champion Bloodline" badge.
• Photo Management: Multiple high-quality photos per dog with a compact gallery view.
• Litter Tracking: Link puppies to breeding records automatically to track weight and health from birth.

🧬 Breeding & Genetics

• Interactive Pedigree: 5-generation trees with zoom/pan. Toggle the Reverse Pedigree switch to see descendant lineage.
• Trial Pairing Simulator: Calculate Wright's Inbreeding Coefficient (COI) instantly. Identifies common ancestors and providing risk badges (Low/Moderate/High).
• Heat Cycles: Track female cycles on the calendar. Includes projected whelping alerts (indigo windows) and expected due dates.
• Health Records: OFA clearances (hip, elbow, patella, heart, eyes, thyroid), GRCA/CHIC clearance summaries, vaccinations, exams, surgeries, and medications — with supporting-document upload.
• DNA Panel: Golden Retriever genetic markers (PRA, ICH, NCL, DM, MD) with carrier-risk checks on trial pairings.

❓ Troubleshooting

• COI shows 0.00%?: Ensure both parents are mapped and have shared ancestors.

• Logo not appearing?: Place br-logo.png in the static/ directory.
