Do Belgian Tervurens bark a lot?

Yes, some Belgian Tervurens bark a lot. They are alert and protective, so they’ll readily bark to alert their family of anything unusual or to communicate excitement or frustration. 

While their barking can be useful for warning you of potential dangers, it can become excessive if they aren’t well socialized or provided with enough daily exercise, mental enrichment, companionship, and restorative rest.
