Can I get a dog?

This question has been asked many times lately. Kaden really wants a dog. He got a DOG book for Christmas and asks me to read it most nights and then he shows me which breed he wants which is pictured above it doesn't change he wants a long haired chihuahua and wants to name him Rooney. We are not dog people. I do like them I just want them to live with someone else. We used to have a dog and had to get rid of her for many reasons after Kaden was born. I always say we will see when he asks. Then the other night I told him that dogs are alot of work and he said "I know Momma you have to give them dog water, big bags of dog food, and take them for walks". I know all boys need a dog. Maybe in a few years but not now.
