I hear ya, Vanessa! I'm 27 and still asking!
Until I get one, I pretty much claim my mom's as mine...even though I live in another city
Trust me though, I call about 7 times a day asking about them!
I do know how you feel, but you are probably going to have a lot less time to spend with a dog when you go to college - and I think the dog would really be confused if you had to give it to your parents when you went away, or sad if it was always home when you were at class or out with your friends... I'm in my 3rd year of medical school, and am just hoping maybe during my 4th year when things calm down...but then I have to worry about residency...
I know you don't want to hear this, and neither do I really, but give it time - you have plenty of time to get a dog...and you even have 11 years on me
trust me I know the feeling on wanting one!!! (it's the only reason I'm on YT...scouting for one) but at least when we finally do get dogs of our own, we'll really appreciate them cause it took so long getting them!
