Tinker's birthday is March 16.....she's going to be 1 yr. old!!!!

. I was wondering if anyone could give me any suggestions on how to make a good doggy friendly birthday cake. She's only 2 1/2 lbs, and she may not eat a lot but she deserves a b-day cake anyway. Any suggestions and ideas are extremely appreciated!! I would also like to hear what everyone did for their little angel's bday!!
