As I observed some years ago, John T. Kennedy is a Rat Terrier. I could go on, but the Rat Terrier Club of America describes him best.
“The Rat Terrier is an American breed that originated from a mixture of crosses by early immigrants of this country… Bred primarily for farm and ranch dogs to hunt, protect and guard against vermin and varmints, Rat Terriers have strong jaws and are known for their quick, agile movements, which enable them to kill rats and other vermin and small game… These early crosses eventually gave the breed the speed and “nose”, as well as the good disposition they are known for today. A non-sparing, playful, happy-go-lucky, devoted companion that is also protective, and yet can be aloof with strangers. They are an efficient, intuitive hunter as well as an energetic and intelligent companion, at home in the city or country.”
In other words, if you find yourself cornered, you’d best pack a lunch because it will be a long day.
