Malorie, just make sure your parents are aware of the responsibilities a dog will bring before you get one. I understand it will be 'your' dog, and hopefully you will assist in feeding, walking, taking care of it, etc. But obviously, your parents will be the ones who will have to pay for its care, and who will have to deal with the consequences when the dog has an accident on the new carpet or chews a pair of shoes. I understand how cute ALL puppies are. But I know of many families who got a cute puppy 'for the kids', only to give it away to a shelter within a few months because it would be left home all day while the parents were at work and the kids at school, and would end up destroying the house. And once the dog goes to a shelter, who knows what will become of it....if it will live in a tiny cage for years waiting to be adopted, or be put down. Just think about what would happen if your parents decided they weren't prepared for the responsibilities of a dog, so make sure they know what they are getting into.
If your parents are experienced with dogs and have a good idea of the responsibilities involved, then great, a well-cared for and trained dog can be an excellent companion. However, if you don't think they know or care much about dogs but will get one for you because you want one, then please think about the welfare of the dog and that ultimately, the responsibilities in this case will be on your parents.
