Its funny, whenever i see posts on here about folk getting a dog, there is always a barage of "noooo, don't do it, it will ruin your life, you dont know enough about dogs, you wont look after it properly and you'll end up rehoming it" I find it really frustrating.
I have two dogs, they fit in with us, not the other way around - i don't work at the moment so they are not left that much but i will quite happily leave them up to about six hours, if i know im to be a long time i arrange for my mum to let them out for a piddle. They sleep in our bedroom, one on the floor, the other on the bed - they are JRTs, i have shared my bed with a rottie before though 
The only real bind for us is holidays as i wont leave them in kennels and my mum can't really cope with them both for extended periods, so they have to come with us. The only reason kennels is a no no for us is one of them is a rescue.
Maybe because i have not been without a dog for more than a month since i was seven, i just don't see them as hard work, even the toilet training was plain sailing. Yes there have been accidents - the best one was when my big dog got stuck in the toilet one evening, got stressed and got explosive shits everywhere, i had to, in this order - strip to bra and pants (it was really easier) rudimentary clean of bath and bathroom floor - bath dog, dry dog, clean bathroom properly, bath myself!
So long as you research breeds that fit in with your lifestyle, get dog from reputable breeder, rescue, ensure they have food, exercise, veterinary care - its not rocket science. Its FUN!
It sounds like you would not have problems with holidays, im sure your mum would step in, you will have plenty of advice from your breeder
and Scruff is a bloody brilliant name!
