We will fight this battle someday here...when people realize more that our breed exists. It's something malamute owners have been dealing with for a long time - when wolf cross owners want to avoid detection from breed specific legislation, home owners insurance, or if the wolf cross is involved in some sort of legal trouble. I think it is only sometime until the owner of a wolfcross (or other mixed-breed with some similarity) claims it to be a Vlcak here...hopefully not in the case of the dog biting someone or attacking another dog. And of course we have Tamaskans etc. here, but so far (other than Aatu people trying to use our males for studs
) we have had no problems with any of the Tamaskan factions trying to claim they are pure Vlcaks or vice versa. But no, I don't guess there is any way to stop other people from making false claims.
You can only protect yourself as best you can...build a good public image with the breed, get them involved where they are seen in a happy way - dog sport, therapy work, etc. I am adament about making sure there are no questions about what or how my dogs or their offspring are, especially for breed "outsiders"...in any way I can - AKC pedigree, DNA profile, importing dogs from reputable breeders, training in many different things, making sure my dog is always under control and social if it is out in public.
