We have two dogs and just teach them not to 'hang' over the dinner table ;) Personally I find counter-high tables very awkward. If you have little kids, they are more difficult to climb up to. Also, my mother is about 5 feet tall- she can't even climb up onto one of those high stools or chairs without help and once there, she feels trapped! She just perches there with her feet dangling and cannot get back down without someone to help her. So personally I would avoid them- but you should do whatever YOU are comfortable with!
