Here is a fun favor idea. Custom made wooden doggie boxes with an extra piece of wedding cake in each box. How many times have you been to a wedding and between toasts, dancing, photo ops, greeting of the bride and groom do you miss out on tasting cake! I love this idea! You can use other material like cardboard of course to make it more affordable and adorn with a custom doggie tag in line with your wedding theme and colors.
