Dog Health Questions: How can I prove more to my mom that I am responsible enough for a dog [not puppy]? She wants one too?

I have a job and am currently saving up for a dog fund (and an emergency fund), I've been researching for months about dog training, nutrition, everything there is to know about taking care of a dog and also the breed I am getting.
I have good grades, no trouble issues, clean room, used to volunteer for a dog shelter for awhile, I'm a "make a plan first" kind of person, and plenty of free time to take care of a dog. She already believes I can afford the dog however she still doubts that I'll take care of it 100% of the time.
My mom doesn't mind and would love to play with it [planning on a chihuahua] while I'm at school however she does not want to do the dirty work (walking, training, etc.) and I understand. She most likely will give in and trust that I won't be lazy as she isn't that stubborn.
But for now, how can I prove to her that I wont be lazy and slack off of my responsibilities?

The Evolution of Dog Training

Recommended Answer:
Do something that is extremely tough for you and that she knows is but never give up on it. Keep doing it for a month or so and see what she thinks about that dog you want to get.

Finding the Essential Dog Training Supplies

• Go back and volunteer at the local shelter - walking the dogs, etc...
  
  Who will care for the dog once you're off to college? YOUR MOM WILL...so regardless of NOW, think of the future as well.
  
  Remember that the first year is pretty expensive - vaccines, spaying, etc...and the last years of a dogs life are expensive as well...good food, parasite preventative, training, vaccines, bloodwork, vet checkups, dental care, basic supplies - can all add up...having a dog is a huge responsibility.
  
  Be ready to give up ALOT OF STUFF for the dog!


• Well, the thing is, no one ever really CAN take care of an animal 100% of the time, because lets face it- we're not superhuman- sometimes we're not home, we have work to do, or something else crops up.
  
  Don't promise your mom that having to do those things will NEVER happen, just make sure she knows that 9 out of 10 times, you'll be the one doing the 'dirty work'.


• Make like a report about it and show like a peace of paper of responisibility idk and if u have a petland. go to there and bring ur mom show her the cute dogs, BUT DONT BUT THEM THERE, BUY THEM FORM A BREEDER!!!!!!!!!!!1111


• Prove it to her by doing a responsible action. Like if you don't clean your room start cleaning it or if you don't do your chores do them without complaining,


• Tell her that you will buy it and if you don't take full care of it then she can bring the dog back to the petstore or shelter.


• maybe your mom wants a Nargle instead


• I convined my parents too not sure how though...it mostly depends what kind of parents you have. I did the same thing you did though.


• Have a huge party and say I was able to organize this I think I can handle a dog.


• Just keep telling her. And do things around the house and in front of her to demonstrate to her how well you will do.
