Hm, well maybe to start you should start being well behaved kids. Also just because you like ONE dog doesn't mean you will like another. I mean, if you have a history of hating dogs, one good dog, does not make an animal lover. I suggest you volunteer some time at a rescue or humane society and get a bit more breed knowledge first. Walk some dogs, learn more about them, including how to care for them. Do they have any pet safety classes in your area? I would suggest taking that to learn more. Owning a dog is a huge responsibility and being "not well behaved boys" it doesn't sound like you are ready for that. Make some changes in that area and then talk to your mom about your feelings. Part of that "being responsible" will mean, understanding and respecting her feelings and decision. Getting a dog might be a long term goal and one you should start educating yourself about now. Good luck to you.
