We are planning to purchase a house, near our local Greyhound race track, in order to take dogs, who no longer race, into a home setting. They will be exposed to things such as mirrors, glass doors, stairs, furniture, etc. As a race dog, they live in 3 x 3' cages and are let out to train and deficate. They have not been exposed to home life. The home will be like a half way house. Most Greyhounds learn very quickly where the couch is and not to run through a sliding door window.
