The dogs must remain kenneled until they are adopted. Some folks that have permanent dogs prefer to kennel them at night and when they are not home, so foster parents are instructed to not deviate from this until they "return" or keep the dog. Copper is allowed on the furniture but "Penny" is not because the potential is there for her to go to someone who does not wish to have dogs on furniture. Kenneled dogs are very easy to house train, they will almost never make a mess in their crate, and as long as you quickly give them the opportunity to go outside, once out of the cage they catch on extremely quick.
BeeCommander. These dogs virtually come right off the tracks. "Penny" raced up until just a couple weeks ago. They know nothing of houses, and carpet, stairs, cars, other breeds of dogs (all they have ever seen are other greys). The whole world is something new to them and they adjust well if given the chance, especially if shown affection, perhaps something they didn't get a lot of.
"Penny" slept right through the night last night without any problems, no whining, no needing to go out, etc. Given they were trailer-ed up here from Florida over 32 to 34 hours, unloaded at GPAC, inspected by a vet, had blood drawn, vet appointments booked, and then possibly a ride to a foster home, they have had their worlds turned upside down, but greyhounds are one of the most forgiving dogs I know of.
