for yoshi i get her doggy cupcakes and doggy pizzas at the dog dish
she usually gets new bowls and a new collar.
its usually just me and her or me and a few friends and her since she prefers people to other dogs *doesn't hate other dogs just likes the attention from people more*
i know a few people i work with think i'm weird but how i see it is they don't live nearly as long as we do. i don't see anything wrong with giving them a special day once a year
*of course yoshi also gets a gotcha day and christmas* XD
