There is absolutely nothing special about the cake design. The cake and frosting though are both dog friendly. I made a 6" heart shaped cake done with a basketweave pattern. I did this cake for my dog's Sweet 16 Birthday. She is 15 months cancer free, and just yesterday her vet announced her to be in perfect health (other than her arthritis and loss of hearing - both due to old age). I know the rules say we can't post photos with faces in them, but I hope this is an exception that is permissible. One of the photos is of my Shelby with her cake.
