For my daughter's 7th birthday she chose a Puppy theme.  We had a friend paint puppy faces on the kids as they arrived.  Next came the pinning on of puppy ears made out of felt. After this, came our first craft.  The kids made "collars" (more like necklaces) out of pony beads and a tag to go on them made with round key holder tags that have a blank space for you to identify your keys on (the kids wrote their "puppy" names on these).  By then our puppies were hungry so we let them have a snack of dry dog food (round shaped dry cereal) in dog bowls (cheap plastic bowls that we bought and decorated with sticker puppy paw prints). I had made dog bones (ginger bread recipe used for cookies cut with bone-shaped cookie cutter), which we hid to play a game of dog bone search.  We gave each child a little map with clues on it and they went around until they found the hidden treasure (the dog bone-shaped cookies).  We also had a T-shirt painting activity.  I bought several dog, bone, and paw print-shaped sponges (at the craft store) and let the kids decorate their own T-shirts.  My daughter and I also spent several very fun hours transforming an empty washing machine box into a dog house prior to the day of the party, which the kids used to play in during and after the party.  All crafts were included in the goodie bags, as were the cookies. My daughter (and her friends) had so much fun at this party that she wrote a school composition on it!
