Hi, just joined really because I was looking up a dog I've just rescued (she's not mine sadly, I've just moved her from trainer into RGT kennels) in Birmingham and found her brother listed in your care!
Since it's so rare you ever find a greyhounds siblings I thought I'd post and say if Sammy's owners should want to investigate his sister (or even adopt, you never know), she's in RGT Perry Barr and is called Sue, she looks just like him.
