I hope they get all adopted properly, my ex-racer has been living the life the past 8 years.
My only worry is finding a good outlet for these dogs. They are working dogs and their mild temperament comes from racing. Have met some non racing greyhounds and they are like a ball of energy that is just waiting for release. Much harder to take care of than an ex-racer imo.
The greyhound brain is like a pressure cooker. If given somewhere to vent periodically, they are fine. They go off like a rocket for 10-20 minutes, then are happy to dose the day away.
This is also why lurchers (greyhound crosses) are so universally crazy. That pressure cooker has a nice big crack in it. It vents into the instincts of the cross. It can be great fun, but it requires some management to keep from being problematic.
