Are Belgian Tervurens friendly?

Yes, Belgian Tervurens are often friendly with their family and can be friendly with strangers if they are thoroughly socialized and have a more confident personality. Under-socialized Belgian Tervurens, however, are much more likely to feel wary and reserved around strangers, and some may always be a bit reserved with unfamiliar people, even if they are well-socialized. They are best suited for adopters who understand their needs.
