Thank you for the information regarding registration of the HSD. I have no intentions of breeding so the spay or neuter requirement isn't an issue. I'd wait until after the pup is over one year old due to bone development concerns.
Most of the training groups in my area are involved in UKC . Do you know how that registry would work? I've done some cursory checking but don't know anything for sure yet.
My choice of dog is totally "non-political". Actually hubby was pushing for another dog after the loss of our 15 yr old Jack Russell followed by the loss of our 10 yr old Dobe. He has had his eye on a Havanese for a couple of years. The breeder was fun to talk to and very thorough. Health testing was emphasized, a very important thing to me.
I spent the last six months of our intact male Dobe's life dedicated to his medical care, most of it through Michigan State University. He came from lines that were all health tested and known for longevity. Everything he shouldn't have suffered he suffered. I sure hope we don't have to go through anything like that again.
While you shouldn't do AGILITY until your pup is over a year, there is absolutely NO reason to wait on obedience training (which includes rally moves) that long. There is nothing done in obedience training at the lower levels that can in anyway injure your puppy. Even if you got to the point that you were doing the obedience jumping exercises (unlikely in your puppy's first year) you can teach them all they need to know with a bar on the ground, then raise the height slowly as they approach the one year mark.
We don't have a TON of UKC in this area (although there is some) and I haven't done it. I'm not sure if HSD are a "recognized breed" with them or not. I do know that the people who show UKC love it, and if the DO recognize HSD's, they have conformation classes for spayed/neutered dogs, so you can have fun playing in the conformation ring too!
As I said, I was trying to give you the "non-political" information on the differences, just to make sure you understood. Believe me, since I got Kodi at the height of the "flame wars", and he is double registered, I CERTAINLY took my share of it. I wouldn't wish that on anybody!!!
Fortunately, MOST people have settled down now, and while there is still SOME vitriol left around, most people are pretty willing to live and let live. There have been quite a few HSD people at the Havanese national specialty the two times I've been there, and everyone was pleasant to each other.
While the HSD people are excellent about health testing, (which is why the originally broke off from main stream Havanese) the GOOD thing that followed all the nastiness is that many more Havanese breeders (virtually ALL of the GOOD breeders) now thoroughly health test their breeding stock. There are still BAD Havanese breeders out there, but my guess is that not all the HSD breeders do everything I'd want done either. You just can't control individuals that much.
One thing that HSD breeders do, that many fewer Havanese breeders do (although there are Havanese breeders who DO do it, or will if you specifically request it) is "soaped" photos of the parents and the puppies you are interested in. The breeder of my older two has soaped photos of all her breeding stock on her web page. Proof positive that the dogs have straight legs and good conformation. The breeder of my younger puppy didn't soap the parents (as far as I know... I never saw photos) but we did do soaps of the puppies before I committed to Panda. I loved her personality, but a dog with poor conformation or crooked lags is not useful to me as a sound performance dog. So, for other people reading this, whether you are purchasing a Havanese or a Havana Silk Dog, if you are serious about performance competition, ask for soaped pictures. While most good Havanese and Silk Dog people have removed most of the CD dogs from their breeding pool, there are still plenty of bad fronts out there, in both "flavors". And just like with a horse, a bad front isn't going to hold up to a lot of jumping, even if you wait until over a year to start doing it.
Congratulations on your decision! As long as you are OK with not being AKC registered (which really doesn't matter if you plan to spay/neuter) you can find lovely puppies and great breeders from both groups. We expect lots of pictures!!!
