The "External Dogs" interface does not match the layout and style of the main "Dogs" page. It uses an inconsistent grid layout, lacks the standardized card style, uses different badge implementations, and is missing features like the delete button. Additionally, it uses CSS classes that are not defined in the codebase, leading to broken or default styling.
## Root Cause Analysis
- **Inconsistent Layout**: `DogList.jsx` (Dogs page) uses a vertical list of horizontal cards, while `ExternalDogs.jsx` uses a grid of square-ish cards.
- **Undefined CSS Classes**: `ExternalDogs.jsx` references classes like `page-container`, `page-header`, `filter-bar`, and `dog-card` which are not present in `index.css` or `App.css`.
- **Missing Components**: `ExternalDogs.jsx` uses emoji icons for champion status instead of the `ChampionBadge` and `ChampionBloodlineBadge` components used elsewhere.
- **Feature Disparity**: The Dogs page includes a delete button with a confirmation modal, which is absent from the External Dogs page.
- **Helper Usage**: `ExternalDogs.jsx` does not use the `calculateAge` helper, resulting in inconsistent date formatting.
