So your daughter is 16...are you going to take care of the dog when she goes to college? What about if she starts dating a lot, are you going to be willing to take over the walks?
Picking a dog based solely on appearance is about the worst way to go about choosing a pet that SHOULD be with your family anywhere from 10-15 years, depending on breed and age at the time of purchase/adoption. It can be a starting point, but so many other factors are involved in choosing the right pet.
Does your daughter even want a dog? What is she looking for? I really hope she's not one of those girls just wanting a "purse accessory".
