Design a wooden pet shelter with the following features:

1. **Structure**: Keep the classic rectangular shape but modify the roof to a flat design instead of a peaked one, using lighter wood for a brighter appearance.

2. **Entrance**: Instead of a simple doorway, create a rounded archway for the entrance, adding a small flap for added protection.

3. **Color**: Change the wood stain to a natural light beige color, giving it a more rustic feel.

4. **Decorative Elements**: Introduce simple carvings of paw prints on the sides, replacing any brand logos or references.

5. **Surrounding Elements**: Add a small fenced-in area with a trellis structure behind it, growing climbing plants for added greenery.

6. **Dimensions**: Ensure the shelter is slightly larger to provide more space for the pet, while keeping an enclosed feel. 

This design will create a cozy, functional, and aesthetically pleasing shelter for a pet.
