+Create a filtering system for the dogs listing page with the following features:
+
+1. Add two filter controls:
+   - A dropdown menu for filtering by dog breed
+   - A checkbox for filtering by adoption availability (checked = show only available dogs)
+
+2. Implementation details:
+   - Populate the breed dropdown with all unique breeds from the database
+   - Include an "All Breeds" option as the default selection
+   - Label the checkbox clearly as "Show only available dogs"
+   - Position filters at the top of the dogs listing for visibility
+
+3. User experience:
+   - Apply filters automatically when changed (no separate "Filter" button needed)
+   - Refresh the dogs list immediately when either filter is modified
