Most Westie “behavior problems” are a working terrier doing precisely what it was bred to do, in a house where nobody needs it done.
That framing changes the goal. You are not correcting a fault; you are giving a strong instinct somewhere acceptable to go.
The short version
- Barking, digging and chasing are breed features. They can be redirected, rarely removed.
- Almost all of it worsens with boredom and improves with mental work.
- Punishment-based methods make fear-driven behavior worse and are not recommended by veterinary behavior bodies.
- A sudden new behavior in an adult dog warrants a vet visit before a trainer.
What each behavior is actually for
| Behavior | What it was bred for | What triggers it now | Realistic goal |
|---|---|---|---|
| Barking | Signaling location underground to the handler | Movement outside, doorbells, boredom, isolation | Fewer, shorter episodes on cue |
| Digging | Going to ground after quarry | Scent of rodents, heat, boredom, soft soil | Redirected to a permitted spot |
| Chasing | Pursuing and dispatching vermin | Squirrels, cats, bikes, joggers | Reliable disengagement on cue |
| Resource guarding | Protecting scarce food in a working kennel | Food, chews, beds, sometimes people | Trading rather than confrontation |
| Pulling on leash | Independent forward drive | Scent trails, prey movement | Loose leash in most environments |
| Separation distress | Bred to work alongside a handler | Long absences, routine changes | Comfortable alone for normal working hours |
Barking
The volume is not a training failure; it is the job the breed was built for.
- Identify the trigger. Alert barking, boredom barking and distress barking are different problems needing different answers.
- Manage the environment first. Film on the lower half of the window, or moving the dog’s bed away from the front of the house, often does more than weeks of training.
- Teach an alternative. Reward the dog for coming to you when the doorbell goes, rather than trying to suppress the first bark.
- Meet the mental need. Ten minutes of scentwork tires a terrier more than an hour of walking.
- Never punish alert barking in a dog that is frightened. You remove the warning, not the fear.
Digging
Going to ground is the breed’s original job description. A Westie that digs is not being destructive; it is being a Westie in a garden.
- Give it a legal outlet. A sandpit or a defined corner, seeded with buried toys, works remarkably well.
- Make the illegal spots dull. Chicken wire under the soil surface, or stone over the favorite corner.
- Check for heat. Dogs dig to lie in cool earth. Shade and water reduce summer digging noticeably.
- Rule out rodents. Persistent digging in one spot usually means something is genuinely under it.
- Increase enrichment. Most escalating digging is unspent energy.
Prey drive and chasing
This is the one that cannot be trained away. The realistic aim is a dog that disengages when asked in ordinary conditions — not one you can trust beside a running squirrel.
| Approach | What it does | Verdict |
|---|---|---|
| Long line in open ground | Freedom to sniff without the risk of a chase | The single most useful tool |
| “Leave it” and emergency recall | Buys you the seconds before a chase starts | Worth heavy investment |
| Engage-disengage games | Rewards looking back at you after spotting prey | Highly effective, slow to build |
| Flirt pole and scentwork | Satisfies the drive in a controlled outlet | Excellent, and tiring |
| Secure fencing | Removes the risk entirely at home | Non-negotiable |
| Shock or spray collars | Suppresses behavior through pain or startle | Not recommended; raises fear and aggression risk |
The American Veterinary Society of Animal Behavior sets out position statements on humane, evidence-based dog training methods, including why aversive tools carry a documented welfare risk.
When to see a vet before a trainer
Behavior that appears suddenly in an adult dog, or changes character, is a medical question until proven otherwise.
| Change | Consider |
|---|---|
| New house soiling | Urinary infection, Cushing’s, diabetes and other breed-linked conditions |
| New irritability or snapping | Pain — dental, joints, ears |
| Increased barking in an older dog | Hearing loss, cognitive decline |
| New night restlessness | Cognitive dysfunction, pain |
| Sudden fearfulness | Vision loss, pain, thyroid |
| Compulsive licking or chewing | Allergic skin disease |
What actually works across all of it
- Mental work beats distance. Scatter feeding, snuffle mats, find-it games and short training sessions tire a terrier far more efficiently than walking.
- Be boringly consistent. Terriers test inconsistency faster than most breeds and remember what worked.
- Reward what you want, frequently and immediately, rather than waiting to correct what you do not.
- Manage the environment so the dog cannot rehearse the behavior. Every repetition makes it stronger.
- Get help early for anything involving fear or aggression, from a qualified behaviorist rather than a board-and-train.
Frequently asked questions
Why does my Westie bark so much?
Because the breed was developed to bark underground so a handler could locate it. Common triggers are movement outside, doorbells, boredom and being left alone. Training reduces the frequency; it does not remove the instinct.
How do I stop my Westie digging up the garden?
Give it a permitted digging area seeded with buried toys, make the favored spots physically dull, check for rodents and heat, and increase mental enrichment. Digging that escalates is usually unspent energy.
Can a Westie ever be trusted off leash?
In securely fenced areas, yes. In open unfenced ground, most Westies never become reliable, because prey drive overrides recall. A long line gives freedom without the risk.
Are shock collars effective for prey drive?
They suppress behavior but carry documented risks of increased fear and aggression, and veterinary behavior bodies advise against them. Long lines, disengagement training and secure fencing achieve more, safely.
My Westie has suddenly started growling. What should I do?
See a vet before a trainer. Sudden irritability in an adult dog is very often pain, commonly dental or joint related. Never punish a growl, which is a warning you want the dog to keep giving.
If behavior is why you are struggling
Behavior is the most solvable of the common reasons dogs are given up, and the one where early help changes the outcome most often.
