But to Lady, all cars were alike; and all were signals for wild excitement.
Like too many other collies, she had a mania for rushing at any motor vehicle, and for whizzing along beside it, perilously close to its fast-moving wheels, barking and screaming hysterically and bounding upward at its polished sides.
Nor had punishment and scolding cured her of the trait.

She was an addict at car-chasing.

She was wholly incurable.

There are such dogs.
Soon or late, many of them pay high for the habit.
In early days, Lad also had dashed after motors.

But a single sharp lecture from the Master had taught him that this was one of the direst breaches of the Place's simple Law.
