Just like some humans are different, similarly some dogs are
different. Some like to run and stay active all day long, while other like to relax
on the couch. Though every dog behaves differently from the other, there is
some generalization among breeds which are less energetic than the others.
So if you are planning to buy a dog that should accompany you all the time, chose one from the list. All of them hate to leave your side and prefer staying inside the house plus most of them are easy to train.
