I want a dog for my birthday but my parents say we don't have enough room we are moving to a bigger place in a year but I want this one dog how do I convince them?

If you live with your parents, no matter how old you are, then you need to follow their rules. So, you'll wait until you move, as they already told you.

Good advise. You have something to look forward to in a year. In the meantime, you can research about dogs and discover the breed you would like to get when the time is right.

Until you're an adult and live on your own you don't get to decide what animals to bring into your home. That's just the way it is.

You have a year to save money, buy supplies, research, and show your parents that you're ready to be responsible for a dog.
