For a fun, children's "dog" party theme, here are some ideas! If you have a child that REALLY loves dogs, why not throw them a puppy birthday party? For  invitations use white construction paper and make it into the shape of a dog bone, and write the  party information on the paper. Setup: You can make easy "puppy ear headbands" for the guests and birthday child by purchasing plastic head bands and gluing tan, white, brown, black, or grey felt cut out in the shapes of dog ears onto the headbands. For "plates" buy inexpensive plastic dog food bowls (you can get these at most dollar stores). Make  sure you wash them before using. Then, when the guests arrive, you have "plates" for all their party snacks. If you REALLY want them to act like dogs, have them try to eat with just their mouths, no forks or spoons. A game idea is seeing who can bark and sound the most like a dog, and you can also play "Doggie,  Doggie, Where's Your Bone?" Your "goodie bags" for the party guests, yhou can buy "candy dog food", that are like cookies and  come in a mini plastic dog bowl with a candy bone on top. You can find these at most grocery or candy stores. Have fun putting together this fun "dog party!"
