Training
Chihuahua
MethodPositive reinforcement
Challenges
s:** "Babying" the dog. Owners often carry them everywhere, denying them socialization and exercise, which creates a fearful, neurotic dog.
Tips
- ** Positive reinforcement is the only option. Harsh methods cause them to shut down or bite defensively.
West Highland White Terrier
MethodPositive reinforcement
Challenges
s:** Harsh discipline triggers defensiveness/snapping. They must be convinced that obedience is *their* idea.
Tips
- Keep training sessions short and varied
West Highland White Terrier Considerations
challengeThe "Westitude"
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?".
challengeAlert Barking
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.
challengeSmall Animal Aggression
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.
challengeHandling Intolerance
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.
