The purpose-bred laboratory beagle is a remarkably versatile animal.
It can be used to ingest a toxic compound until it dies and to ascertain human safety guidelines for pesticides. Its heart, brain and prostate are easily accessible for cancer studies. It is bred to be docile and obedient, and, if necessary, it can be purchased sans working vocal cords. For around $700, you get a 33?pound specimen that needs no more than eight square feet of kennel space, per federal law.
