Thank you all, so much!! This really helped. I'm reconsidering just waiting until college is over.. or at least my last year or two of college when I get my own place!
But the advice really did help, I want to be fair with the dog - not just get one now, get attached, then ditch in a couple years for college /: That wouldn't be so fair to my parents either.. so if all in all we DO decide to get one it will be more of a family thing.
Again, thanks!
