My dog is fearful and barks/nips at strangers on walks. Why?
Hello, and thanks for your question. Most “aggression” issues in dogs are ultimately based on fear to some degree, so I would suspect this is at least partially fear based. Maggie knows that your family is her “pack”, and she’s nervous of outsiders. Every time she barks/growls at others and they end up walking away, she may be reinforcing to herself that “hey - this works! I should keep scaring strangers away!”
If this is a behavior you want to work on (and I would recommend it, before it escalates to biting a visitor or stranger on the street) I highly recommend recruiting the expertise of a professional. Ideally a veterinary behaviorist, but your primary vet may be able to direct you to trainers they recommend. Behavior concerns require a lot of time, effort, patience, and consistency, and it’s important to give Maggie the right response at the right moment, before she’s too worked up to be receptive to you. A professional can help you learn how to read these subtle signs before Maggie is completely overstimulated.
