Lucky and Flo, twin Black Labrador counterfeit-detection dogs who became famous in 2007 for "sniffing out nearly 2 million counterfeit DVDs" on a six-month secondment to Malaysia in 2007. Following the multimillion-dollar, 6-arrest Malaysian detection, they became the first dogs to be awarded Malaysia's "outstanding service award" and software pirates were stated to have put a £30,000 contract out for their lives.
A vigorous dog may or may not be high-energy, but everything he does, he does with vigor: he strains on the leash (until you train him not to), tries to plow through obstacles, and even eats and drinks with great big gulps. These dynamos need lots of training to learn good manners, and may not be the best fit for a home with young kids or someone who's elderly or frail. A low-vigor dog, on the other hand, has a more subdued approach to life.
