Technically....Puggles are mix of pugs and beagles...the ones I've seen seem pretty healthy and good-natured (and are actually really really cute), but I wouldn't pay for them than for any other mixed breed. Beagles are pretty healthy, but hard-head and pugs are generally extremely sweet but of course have a whole palette of health issues to choose from...so it's not that bad a cross...you get a dog with a longer snout and a good temperament. But....it's still just a mutt. :-)
