Your still very young dogs sound enchanting, and extremely well loved, like most well cared for well adjusted family dogs, just like those we all own here, and also the many dogs of any breed or cross, mongrel, non breed that are well owned and sound in body and mind.
To give an informed judgement on a breed/type of dog really needs you to have experience of dogs from cradle to grave, several generations and a broad cross section of bloodlines to be able to say this is 'typical' rather than this is what 'my' dog is like.
The comments about Northern Inuit, Utonogan, Tamaskan met in discussions is not about the individual dogs, it is the concept of them as a breed in development, and the process, ethics and goals in achieving this.
Sadly it seems that there is no real aim, lots of disagreements (typical in all human activities), and far too much inbreeding of a small original set of bloodlines, which history has shown us gives rise to the problems many breeds have been left with now..
There seems to be no real agreement about what the end result is to be in terms of looks, usage or temperament other than that they are generally Wolfy/Spitz type.
There is a whole raft of established, in many cases ancient Spitz breeds, in fact in FCI countries they have their own Group (5) and this is further subdivided, for example Sled dogs, Northern hunting dogs, etc.
So bearing in mind how difficult it would be to establish a new breed that is healthy, the amount of wastage (animals that do not fit into the breeding program to achieve the aims of the breed) and how long even the chosen individuals will take to breed true to even a broad interpretation of type is there any real purpose in doing so. Many of us feel the people involved are at best misguided (and in many cases jumping on a Fashion bandwagon, n order to sell puppies,a dn yes it has happened with many breeds over the years, from 'Dulux' dogs to '101 Dalmatians', 'Hush puppies' and now 'snow dogs').
The energies of the people involved in breeding would be far better spent supporting existing breeds breeding programs, as some of the breeds are quite rare, to enable them to remain sound and healthy or improve where needed.
There really is no need to re-invent the wheel, and make the mistakes made in breeds in the past that we are all busy avoiding/fixing.
I suggest you may like to Visit the one show in the UK where all our recognised Spitz breeds come together in November at the 'Nordic'.
You can see the breeds in decent representative numbers at championship shows, but unfortunately in the UK they are spread out among all the groups except Gundog and Terrier.
