Bouvier des Flandres Considerations

dealbreakerProtective Aggression

Without extensive early socialization, may decide no strangers are permitted on property. Naturally suspicious and territorial.

dealbreakerSame-Sex Aggression

Many Bouviers, particularly males, will not tolerate another dog of the same sex once they reach maturity (18-24 months).

challengeThe Dirty Beard Reality

Drinks water and soaks beard, tracks mud and debris. If you're house-proud or dislike wet dog smell, this is a severe mismatch.
