Some puppies can be very destructive, some aren't. All puppies need to be watched; if a puppy must be left alone, it should be provided with a safe place to stay (perhaps a crate) and safe toys to chew.
IW puppies housebreak rather quickly; a crate can be helpful, especially overnight. However, while crating can be a useful housebreaking tool, they should never be crated routinely for long periods of time (such as during work hours), which can be detrimental to muscles and joints, and encourage formation of bursas. Long hours of crating or kenneling with little opportunity for socialization can foster timidity in a hound and leave their personalities undeveloped.
