I know exactly how you feel, I felt this for about 9 months ago. Tell them you promise to help around the house alot more, and that kind of stuff. Parents will like it more, and it will show your mature. For me to get Elvis I had to clean my room everyday, put the dishes away from the dishwasher, Do house related chores, and I ecspecially had to respect everyone in the house, meaning no back talking, or yelling. It was alot of work, but heck, it was well worth it. I wanted my dog now, but I learned that these thing cannot be rushed. It will take time, and be patient. Show them you have the responsibility to take care of a dog. They will like that, and it can make your dreams of owning a dog come sooner!
