I think you have made your decision. I was alot like you: people were making a lot of arguments against my decision- money potty training time etc. And just like you I made arguments right back!
I think that it shows your are determined and dedicated. && your schedule is perfect (for a puppy lol). Just buy an exercise pen so that it wont pee everywhere!
Oh and I dont like the long hair either I plan on keepin it short- much easier! (and cuter)
I say go for it. Check the puppies for sale forum here... good luck. Maybe post a thread in breeders section looking for a breeder near you. I hope you find a pup
