The Belgian Tervuren is a visually striking herding dog. The quick intelligence, stamina, and agility of the Tervuren allow it to excel in an extraordinary array of tasks.

Are you interested in this breed? The OFA, working with the American Belgian Tervuren Club, recommends the following basic health screening tests for all breeding stock:
- Hip Dysplasia (OFA or PennHip)
- Elbow Dysplasia
- ACVO Eye Exam
