I shy away from 'designer' dogs, in general, but his position was that pugs have become shorter lived, and he didn't want to become attached to a dog, which they treat like family, as we all do, only to have him/her pass away after too few years. I believe that he was talking from experience.
I've seen others of this cross, and they don't impress me, look-wise. It sounds like whomever bred this dog is getting it down pat. Now, if only their motives aren't to make money... I wouldn't ask him about that end of it, of course.
Also, I have to say, the breathing, slight leanness, and overall body and health seemed so much better than the pure pugs that I've seen of late.
My mother had pugs before she was married, and they, too, were less stout, and overall healthier seeming. They didn't have as many breathing problems, and lived a pretty normal life span.
Like many breeds of dogs, and cats for that matter, I think that breeders have over-emphasized certain physical traits until the animals are less healthy.
The flatness of a face being too extreme, heads too large, back hips too low, and we won't even talk about Siamese cats.
