What do you mean by a normal dog?

. If you mean an actual breed of pedigree dog, I would recommend one if your requests were for:
A puppy whose history and background you knew
Had strict requirement for adult size/appearance and wanted to know exactly what you were getting
Wanted a well bred dog whose parents had all the relevant health tests
Were for a specific breed
A specific activity, showing/agility/field & trial etc, where getting a breed that excels at those tasks will put you at an instant advantage
Want a specific breed that has a minefield of health problems , as going to a decent breeder will help you eliminate those as much as possible
However, your requirements aren't for any of these (or you haven't said if they are), so a rescue dog would suit your needs adequately, if you do your research and choose the right dog, and the right rescue.
I will say if you want a dog that isn't too active or demanding exercise wise and will sit by your side as company whilst your working, I would be looking at dogs from either the toy group who are naturally bred to be companion dogs (though can still be spirited) , or the utility group which consist of breeds that originally were bred for a task but have gone out of purpose and are now just kept as pets. The other groups are full of breeds bred to work not sit by the fire and aren't going to be 'low maintenance and not too lively'.
