Tell her you are responsible
you can say mom if you give me a dog i will be a good boy or girl if she denies then say that you will do somethin that she has always wanted you or somebody to do for her
A goldenretriver is easy to trained and is very good
this is very difficult!!!you must convince her that you will take care of it,clean his mess,be responsible etc....of course you must do these things when you finally bring the dog at home. extra advice:choose a dog from a shelter than a pet store,you will save his\her life (and your mom will not blame it for the money she lost)
I would say boyfriend( or husband if she's married)
convince herif it doesn't work convince your dad
Brownose
Just keep asking her about it. It actually took me three years to convince my mom and dad to let me get my bellybutton pierced.
mom a little dog is cuter than a big dog
sorry but that really depends on your mom....
Move out.
Buy your own
Just ask her for one
