Dogs are pack animals....if they are suited (size, coat, temperament) for living outdoors they still need company/socialization/work....And shelter!!! I have a malamute, loves to be outside when it is cold, inside in A/C when it's hot. But she does not want to be left out alone all day....she wants her pack. Many dogs develop problems if they are kept outside - they can get bored and/or lonely...... digging, barking are just some of them. Also ticks, fleas etc often more of a problem. If you can't keep both dogs together, inside...I would not get another dog....JMHO
