Scottish Terriers are famous for biting, but even if they weren't....the reporter reached down too quickly toward the dog.

When petting a "strange to you" dog, you should lower your stature, offer your hand only part way (slowly), and do not look the dog in the eye. If the animal accepts your advance...then you MIGHT get away with petting it.

Personally, I chose NOT to advance upon animals unless they are displaying absolutely unmistakable signs of friendliness.
