What kind of birthday celebration do you give your dog?

We never did a proper birthday for Roman. We've always wanted to, but we don't know when he's born! We don't have his certificate from the shelter from his previous owners and from the two vets that he's been to, both have different dates. One says October of 1999, and the other says January of 1999. We try to stray towards January because it's always easier to remember being the beginning of the year. But this year, we're going to celebrate it for him. He's going to be 15 years old, which is remarkable!

I want to buy him a cute little cake from the dog store down the street. It's such an expensive place, but it's completely worth it for Roman. He's been through a lot and he deserves the best 15th Birthday.
