When we were growing up, me and my little sister shared a room - there was the great divide - cats on my side, dogs on hers! How fun would a dog themed party be for a little boy (or girl)...so here are some ideas to Frost a dog themed party!
This, I believe, was for a dog, but would be perfect for human food too! I love the fake grass and all the bright colors! Source
Make dog bone shaped placemats from kraft paper and use dog bowls as favor holders! You could use them as bowls on your buffet too. Source
Get miniature dog houses (from unfinished stuff at the craft store) and let the kids decorate as their activity! You can even set up a station where they can "adopt" a dog plush. Source
Chocolate paws would be a perfect favor! I love the little paw ribbon and vase, too! Source
Make this a "human" cake by making dog bone cookies... because the pendant banner and bow are too cute to pass up! Source
