What you need is a dog that will make you feel as if you are the most important, wonderful, resourceful, provident person in the whole wide world. In short, a Labrador retriever. This breed started out its career pulling hawsers in frigid North Atlantic ports and graduated to retrieving dead ducks for the price of a few pats and the occasional “good dog.” But the Lab would, in fact, do the work for free. He loves you–adores you–this much. There is a reason, after all, why the Lab is America’s most popular breed. Get a Lab and you don’t just have a friend; you’ve got a full-time fan club.

Ever been backed down by your own shadow? Do you over-tip so the cab driver won’t sneer at you? Does that chick on Alias scare the bejesus out of you? Well, you need to get yourself a dog that will set an example of toughness and aggression and put a little steel in your spine. And if that doesn’t work and people still think you are a wimp, at least they will mind their manners as long as the dog is standing there next to you, showing its teeth. The rottweiler is the quintessential guard dog, and 10 years ago was America’s second-most-popular breed.

You sometimes worry that you’re a candidate for the earliest onset of Alzheimer’s on record. Or you have so many things going on at once that you don’t merely forget where you left your car keys–you forget where you left your car. The companionship of a dog with single-minded focus might help. One of the hunting breeds, perhaps. Beagles are agreeable dogs and pleasant enough to be around. But all things considered, they would rather be scenting and chasing game. It is in their DNA. Once they are on the trail of a rabbit, fox, deer, or whatever, they cannot be distracted. That can make taking the dog for a walk an interesting exercise in learning to focus on something other than yourself.

No breed is more laid-back than the golden retriever. Perhaps it is the Scottish ancestry that has made this sporting dog so disinclined to waste its most precious asset–óenergy. Whereas a Lab will retrieve a thrown ball until its owner needs rotator-cuff surgery, the golden will do a dozen retrieves and then look for a place to rest. A great low-maintenance dog, the golden does do one thing vigorously–grow hair. When you get your golden, buy a good vacuum cleaner.

Bred to chase foxes into their dens, the Jack Russell would take on an MMA fighter and might even win. True to its British breeding, the Jack Russell is a world-class stoic and exceedingly loyal. In the presence of a Jack, one never feels more emphatically the truth of the old saying “It isn’t the size of the dog in the fight; it is the size of the fight in the dog.” Substitute “man” for “dog,” and you’ve got your therapeutic payoff.
