Belgian Tervuren vs Nova Scotia Duck Tolling Retriever

This breed has an "arrested" predatory sequence that stops just short of the kill bite, but heavily features the "chase" and "nip" behaviors. They will instinctively nip the heels of running children, cyclists, and joggers. This is often misidentified as aggression, but it is a hardwired working trait that is extremely difficult to train out completely.

Unlike the "loves everyone" temperament of many sporting breeds, the Tervuren is naturally aloof and suspicious. Without extensive early socialization, this caution can escalate into fear-based reactivity or "sharpness" (biting out of defensive fear).

If under-exercised, Tervurens do not just lay around; they deconstruct their environment. They are prone to obsessive-compulsive behaviors like tail chasing, shadow staring, and flank sucking if their mental needs are not met.

This is not a myth. When excited, frustrated, or anticipating work (like a ball throw), Tollers emit a high-pitched, piercing shriek that sounds like a banshee. It is startling to neighbors and can be difficult to train out because it is an involuntary expression of arousal.

Unlike many show-line Golden Retrievers who are happy to lounge after a walk, a Toller often requires relaxation. Without a "job" or rigorous mental stimulation, they can become neurotic, pacing, whining, and destructive.

Tollers are not "everyone's best friend." They are typically aloof with strangers, ignoring them to focus on their owner or a ball. This can be disappointing for owners expecting the social butterfly personality of a Lab or Golden.
