Frequently an adopted greyhound is completely housebroken right from the start.
Greyhounds are kennel trained.
This means that they are taught not to soil their own space. At the track greyhounds are taken three or four times a day to a turnout pen to relieve themselves. As a result, they do not learn how to tell us that they have to go out. There may be an accident or two, but this is best avoided by taking your greyhound out frequently and giving it lots of praise when it finds the right spot. Watch it closely at first, and it will quickly learn that its new home is the place it keeps clean and outside is where it relieves itself.
