Yes. Dogs can be trained to stay off the furniture and not to jump on visitors. Not all dog owners do this; it does take some time, as well as the willingness to say no to the animal even when it's being very cute.

I don't have a dog now, and probably won't again, though I was fond of the one my parents got when I was ten. (Reasons not to get another are both the logistics you discuss (a cat needs love and care, but not two walks a day even when it's snowing heavily or wind chill -15 C) and that none of my partners care for dogs.
