Does she get to eat the food on her head?
Yes, she gets to eat most of the food. In some pictures (doughnut, birthday cake, crab legs, etc) she will receive a treat instead.

What type of dog is she?
Tiger is Staffordshire Terrier and American Bulldog.

Yes, I will give Tiger love, attention, kisses, and belly rubs from all her fans.

EDIT: Nothing is photoshopped.
