Belgian Tervuren vs West Highland White Terrier

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 a true working terrier. They possess a high level of self-esteem and independence. Unlike a Golden Retriever that asks, "What can I do for you?", a Westie asks, "What's in it for me?".

Westies are vocal watchdogs. They will bark at doorbells, squirrels, leaves blowing in the wind, and delivery trucks. This is not a "quiet" apartment dog; their bark is piercing and persistent.

They were bred to kill vermin. They cannot be trusted with hamsters, rabbits, guinea pigs, or birds. This is a genetic kill-switch, not a training issue.

Westies generally do not tolerate rough handling. They are known to snap if pestered, pulled, or startled, making them a risky choice for families with toddlers who lack boundaries.
