Well, Blogger is behaving badly tonight, and I am just hoping that this little guy gets posted! Sweet little face. Lots of pugs have that 'tongue sticking out' thing - but usually AKC breeders are careful not to get tongues that are too long.
See, when we mess with the anatomy (breeding the snout shorter and shorter to be pretty much non-existent, don't get me started on us modifying animals.... much as I love dog breeds) we take lots of chances. To minimize the bad results that could occur (just think - the muzzle gets shorter, but loops, the tongue stays long, or the palette gets shoved back into the esophagus (sp), the eye sockets can be too shallow, etc. etc.) breeders go back a few generations on BOTH parent's sides and see if any of those dogs/bitches have had any problems.
When people do not do this and they just have 2 cute dogs they want to breed, they take big risks - and hey, the puppies are so CUTE, right? But that's what you pay $1,000 or so per puppy for, to get the lineage clear. Nothing's ever guaranteed in life, so things could still pop up, but things that can go wrong can go SO wrong, and break your heart, and cause such sickness and sorrow for all concerned - really, really think before you purchase a dog that is a purebred without papers.
End of lecture!
