Dogs love camping. Dogs love frolicking through fields of fragrant flowers. Dogs hate slip-sliding around in slickery truck beds enroute to flowing fields of fragrant flowers.
Step 1: Convince Man That Dogs Need Flowers
Feed him pizza and beer until he thinks dogs need flowers... in his truck.
Step 2: Turf
Acquire some luscious turf at your local home improvement store. Cut to fit your truck bed. Install.
Step 3: Fragrant Flowers
Pick up a handful of vibrant flowers at your local craft store. You will also need a hot glue gun and some flower foam cylinders.
Arrange your fragrant flowers in beautiful colorful clusters by sharply stabbing them into the flower foam.
Step 4: Grow the Garden
Using the hot glue gun, secure your beautiful blossoms to the green-green grass. Secure the turf to the bed if it slips around.
Add dogs to verify proper arrangement.
Don't fret, that is a peaceful yawn, not a scowl.
The arrangement is much appreciated.
