Do Belgian Shepherds bark a lot?

Yes, Belgian Shepherds bark a lot at times. Belgian Shepherds have a natural inclination to protect their territory and family. While this trait is valuable, it can also contribute to barking if not properly channeled through training. Boredom or lack of physical and mental activity can sometimes lead to increased vocalization. 

Some varieties of Belgian Shepherds, such as the Malinois and Tervuren, are known for being more vocal than others, such as the Groenendael and Laekenois. Proper training can help manage barking behaviors in all Belgian Shepherds.
