Create a detailed mood board that encapsulates the concept of a 'Dog park'. The mood board should contain images that represent various facets of a dog park. Visualize a wide, open green field, where hyperactive dogs of varying breeds are playing fetch with vibrant-colored frisbees. Include leisurely scenes of owners, both male and female from different descents like Caucasian, Hispanic and Middle-Eastern, sitting on well-worn wooden benches chatting while their dogs mingle. Paint a sunny day, with vibrant blue skies dotted with fluffy white clouds. Incorporate elements like dog toys, water bowls, and agility obstacles. Remember to make this collage motivating, vibrant and full of life.
