Training myths
"My dog is protecting me": usually not
It is a flattering story. The dog stands between you and the stranger, the hackles go up, and it feels like devotion. Sometimes owners even encourage it. But a dog who is truly comfortable does not need to bark at the delivery driver or stiffen when a friend sits too close. That costume of protection is usually covering something else.

Fear in a costume
What the barking dog behind your legs is telling you.
Watch where the dog stands. A dog that barks from behind your legs, then backs up, is often frightened and using you as cover. Lowered ears, a tucked tail, lip licking, and lunging forward then retreating are common signs of fear rather than confidence. The noise is meant to make the scary thing go away, and when it does, the barking gets rewarded.
The second costume is guarding. Some dogs treat their owner like a bone or a favourite bed: valuable, and not for sharing. They may stiffen when a partner sits down beside you, growl at another dog who approaches your chair, or freeze when a guest reaches toward you. That is resource guarding, and it can escalate if it is mistaken for affection.
- Barking from behind your legs
- Freezing when someone sits nearby
- Lunging forward, then retreating
- Growling only on the couch
Safety comes first
Management now, training after an assessment.
Start by making incidents less likely. Use a leash, gate or crate when guests arrive, keep the dog off the couch if that is where guarding happens, and give strangers on walks extra space. Never punish growling. A growl is a warning, and a dog punished for warning may skip straight to a bite next time. Keep children well away from this work entirely.
If there has been any snapping or biting, book a professional assessment before trying exercises on your own, and ask your vet whether pain could be part of it. Behaviour Rehab is built for anxiety, reactivity and aggression, with reactivity work at your dog's pace, confidence building and in-depth owner education. Dogs with bite histories are accepted after a full assessment.
Asked and answered
The questions people ask us.
Is my dog being protective or aggressive?
Often it is neither in the way people mean. Many so-called protective displays come from fear or from guarding the owner as a resource. Body language, where the dog stands, and what sets it off tell the story better than the label.
Why does my dog growl when someone sits next to me?
That is often resource guarding, with you as the thing being guarded. Do not punish the growl, since it is a useful warning. Manage the couch and get a professional assessment, especially if there has been any snapping.
Should I let my dog protect me on walks?
No. A dog reacting to strangers on walks is usually stressed, not on duty, and rehearsing it can make it worse. Give people space, keep the leash relaxed, and ask a professional for help.
Can a guarding or fearful dog be trained?
The work starts with a full assessment. Behaviour Rehab is a 5 to 6 week board and train for anxiety, reactivity and aggression at $4,850 to $5,760 + GST, customized after that assessment. At the consultation we will say so honestly if something smaller would suit your dog.
