I’ve never owned a purebred dog (or cat for that matter). They’ve all been ‘mutts,’ or mixed breed animals, rescued from shelters or given to me by friends or family who could no longer handle the responsibility of pet ownership. I am okay with this. Like many people, I even assumed raising mixed breed pets is better—having heard numerous stories about the ‘genetic’ health issues of purebreds. However, a recent study reveals those tales may not necessarily be true.
