A young Ridgeback is a very energetic fellow. But as Ridgebacks
mature, most of them become much more laid back. One author calls
them the "kings of dozing." Some say that a mature Ridgeback is
happiest when either running flat out across a field or flat out
asleep at your feet. In general, they mature into lovely calm dogs
that do well when raised with children and other pets.
