Years ago I was given two 'retired' greyhounds. The bitch had killed her first litter after retirement so she was slated for euthanizing. Instead, the veterinarian brought her to me. The male was younger and been judged not fast enough.

They were lovely dogs. Luckily my hillside acreage was fully fenced so they got plenty of exercise. I say luckily because when I took them for walks I couldn't make them break out of an easy trot. :)
