My aunt has adopted 2 greyhounds that have been retired (or at least one has, I haven't met the other) and some of the stories she's told us are horrible. The animals are mistreated and put into a tiny cage right after they run and are sweaty and breathing hard. I barrel race horses and I have learned that you don't want to tie them up to the trailer right after you run them hard.....they need to be walked out and at the end of the day they need to be brushed out because they're sweaty......if you want more detailed stories about greyhound racing PM me and let me know.
