Make her a cake! I made Delilah one for her birthday and she LOVED it. It had like beef baby food, bacon bits, and some other random things in it. I got the recipe online.
Delilah actually had a first birthday party. I know, I know..I'm ridiculous. I bought dog themed decorations and everything. I invited my friends and their dogs and handed out "goody bags" with pig ears, treats, and balls and such. My friends brought their dogs and brought Delilah gifts..she even got cards from people, LOL. So we all sat and had dinner together and we had a big fenced in area set up for the dogs to play. They all got slices of cake on a doggy themed plate and loved it!
