Freppan,

While I think you are trying to show maturity by making a list of necessities for a new puppy, I personally don't know any 14 year old that can financially take care of all expenses for a dog. I have teenagers so I know how it is with them wanting something right away. And though they walk the dog on occasion and feed him, he is not the focus of their lives with them being in high school, as other normal teen stuff takes up their time.

Since it is just you and your mom. your mom needs to be 100% in agreement with getting this new puppy is right for the two of you, not just 95% sure; since the majority of the expenses will fall on her shoulders, and probably some of the care, and I don't think begging her or trying to guilt trip her into getting this dog is a good idea.

I am wondering what are your plans are 4 years from now? Do you plan on leaving home for college or do you plan to live at home and attend school or will you be moving out to work full time? If you will be going away to college, has your mom agreed to taking care of this dog full time at that point? Moving out will require housing that will accept dogs; they are available, but not always easy to find.

And unexpected vet expenses will happen. This dog will be your responsiblity for the next 12 - 15 years of your life which will put you in your mid twenties and so much will change in your life between now and then. And while I think dog sitting for your aunts dog is a good idea and responsible of you, it is not the same as being the owner of one in which you bear the responsibility of all costs and care.

And I agree with others have said in searching out a good breeder who does the necessary health tests, which will give you better odds of having a healthier dog in the long run.
