This is a dutch wolfdog forum but there is also a English corner at the bottom of this forum.
There comes people with all kinds of wolfdogs so even Saarloos people and breeders. But the most saarloos breeders in NL and Belgium and Germany won't ship a puppy of theirs to a far country. That is one of the reasons that outside Europe you will not find a saarloos breeder that have pure saarloos.
