- Do not keep bringing the dog up, this irritates your parents and makes the delay of the dog even longer. Bring it up maybe once every few weeks just as a reminder that you really want one, but don't go over-bored.
- Show your parents you are responsible enough to take care of the dog. You can start by cleaning up around the house and offering to do chorus. This will get your parents thinking that a dog wouldn't be a problem since you are doing so well
- Do almost all the work for them. You can find a good breeder for the dog you want, make sure it doesn't cause any allergies (if you, your parents or any of your friends have them), ask people in your neighborhood what they think of their dog (if they have the same kind you are going for, or same breeder), and present all your information when you think it is the "right" time. Know if it sheds a lot, a little, or not at all (if it is a little or not at all, this can be a key factor for the dog)
- Offer to chip-in with the costs of the dog. Dog's expenses are not cheap, so that may be the reason your parents are holding back. Offer to pay with your money for the dog food, if you really want a dog, allowances are not as important.
- Show your parents the pro's of having a dog, and maybe even the con's. This shows your parents what the good sides and bad sides of the dog is. If you or someone else doesn't do this, your parents may be surprised (and not in a good way) when you get your dog.
