🐕 Managing Your Kennel

• 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.
