These dogs are athletic and can escape from four- to six-foot enclosures with little difficulty. Regular hunting, running, carting, bikejoring, skijoring, mushing, dog scootering or other vigorous activity can alleviate this desire to escape. The natural instinct to hunt may result in the dog hunting alone and sometimes bringing home occasional dead trophies, such as cats, rats, pigeons and other urban animals. In addition to exercise, especially formal hunting, the GSP needs to be taught to distinguish legitimate prey and off limits animals.
