I have no doubt you love little Romeo, he is adorable!
You might want to check out other threads here and in the "Rescue" section and see that it is most likely he comes from a puppy mill. Knowing that, knowing that you have no guarantees about his pedigree and information about health/genetic makup, you will realize you may have a puppy more prone to some health issues. It's just the way pet shops work. No reputable breeder anywhere will ever have a pet shop sell their puppies and the fact that this "breeder" comes from Missouri is a huge red flag, since that is pretty much the capital of puppy mills in the U.S.
I'm not saying this to upset you, Chris. Really! Romeo may be just fine and live a long, healthy life. I just think it's important that more people learn just what "papers" really are, and that organizations other than the AKC are not always good, regulated ones.
If you were not given the name of his breeder and
the full registered names of all those champions in Romeos line and given no proof that proper health tests, such as CERF (for the eyes) and patella/hip tests (posted at ofa.org) where you could check on all those relatives, then there is no guarantee whatsoever and he does not, in fact, have what they say he has in his line. They show so-called "vets" who sign health papers, but again... it's all a farce.
NOT that that makes him a puppy you don't want! My reason for pointing some of these things out is only for education and to hopefully make others aware that pet shops do not sell dogs from reputable kennels and with full health testing done. Some, very few, pet shops will sell dogs from shelters which is fantastic. There is nothing wrong with an "unpurebred" at all. But the vast majority of shops well........ one just needs to be very careful.
Romeo is no doubt very much a Havanese and he is a sweetie pie! I look forward to hearing more about you and your two pups as well as seeing more pics.
