I used to travel to shows with a Finnish Spitz breeder whose dogs were particularly well behaved, but they are quite a fizzy breed, and more so than the Buhunds I know.
Most Spitz are fond of their voices, but no more so than many breeds, it is a matter of training them not to indulge inappropriately.
They are similar size wise, availability equally low. So contact with breed club and getting on a breeders waiting list (may take a year).
We have owners of both breeds who also own my and Nova's breed the Norwegian Elkhound, so they do have appeal to all those who like an independent minded coated natural type Spitz dog. Never a good idea to ahve two pups together, especially in a preferably please themselves breed. I would never advise less than a two year age gap, preferably three.
Another breed gaining a following in the UK, with more of an offstaning coat, liek that of a Samoyed or Keeshond (breeds also worth consiodering) is the Finnish Laphund.
