Wow! Thanks for all the replies guys. I was a little nervous as well with the multiple breeds, but I then saw that Havanese seems to be the main breed and the others on occasion. Since she is relatively close by, I am going to see if we can stop there for a visit to check things out. If I don't get a good vibe, it just isn't meant to be. Thanks again!!
Good idea. DO NOT, I repeat, DO NOT get sucked in by cute puppies!!!! ALL Havanese puppies are to-die-for cute, and it is REALLY easy to buy with your heart instead of your head.
While it looks like this person is doing the proper testing, make sure you look it up on OFFA. Also remember that even with all the testing, and parents with championships, HOW the puppies are raised will have a great deal of bearing on the quality of pet you get. They should be raised underfoot, in sparkling clean surroundings, and AT LEAST partially potty trained by the time you bring them home. (the cleaner the surroundings, the more likely the puppies are to want to keep their surroundings clean, and potty only in appropriate places) They should have an enriched environment, with lots of toys, different floor textures and things to climb on. If the breeders don't have young children, hopefully they have made an effort to have some come visit, so the puppies have that experience too. While not all breeders do this, I was very glad that my breeder had introduced Kodi and his siblings to crates at night during the week before I brought him home. It made the transition to his new home SO much easier.
The new owners have a big responsibility to continue the good up-bringing and ESPECIALLY socialization of the puppy, but you can never fully make up for a bad start while they are in the breeder's care.
