My mini schnauzer is 6 1/2 years old. We own a small business and have had her since 6 wks old. She has never been without human contact. Never been left alone. Comes to work with us every day and has met a lot of customers. We sometimes put her on top of our counter to greet people.
Recently we've noticed a change in her behavior. People are still friendly to her but she now growls and snaps at them. She hasn't bitten anyone yet but that day may come. She especially dislikes children.
What has got in to her? We scold her when this happens but she keeps doing it even to the people she knows and occasionally. She has never bitten me but has snapped at my wife.
