August is the most exciting month of the year, and it is filled with hot sunshine, beach swimming and surfing, and watermelons. If you adopted a new puppy in August, you could consider choosing an August-inspired name for him or her. Of course August itself is a great name, and you could also consider Leo, which is the astrological sign for much of August. Peridot is the gem of the month, and Gladiolus is the flower of the month.
