I've had dogs for years and years, and competed with them in racing and coursing. When doing that, they do take up a lot of time- conditioning, traveling to events, etc. I really enjoyed it, but when my youngest two retired from competition due to injuries, thats when I took up cycling- before that I really didn't have time. Now I still make time for them, but there's no conditioning or traveling to events so I have time for other things. They can take part in the cycling, up to a point, since they enjoy trotting alongside the bike on a springer attachment for exercise occasionally (like when I can only go short distances slowly, like when my 4 year old son goes riding).
As for the doggy smell, anyone who fosters ex-track dogs will have that smell since they are kennel dogs. If the dog lives in the house and has baths when they are dirty, most short haired dogs have little odor. The odor comes from unwashed bedding, etc- only buy dog beds that can be laundered.
Housebreaking can be made easier with a dog door, but some if the dog barks (many hounds do) you may not want her able to go out at all hours of the night.
The pulling while walking can be handled easily enough, with training and maybe type of collar.
If you aren't sure how she'd work out, maybe you could foster her for a while- you'll either fall in love and have to have her, or decide it's not for you.
