what sort of preparations need to be made? what things are they acclimated to by the rescue, and how much further work in that department is necessary? i remember yeeears ago watching a rescue on Animal Planet that took in ex-racing Greyhounds, and some of them had to be introduced to many things for the very first time, things that we face everyday like stairs and umbrellas. is that typical? aside from general health issues in the breed, are there specific health issues linked directly with racing that adopters should be on the lookout for when taking in a dog?
