So the dam to them is my old brindle bitch call Bonnie ....her dame was 5/8 Greyhound 3/8 collie.....her sire was a Grew....first cross grey x racing whippet...Mick Dadd from Sheffield bred her....so she's very whippety Greyhoundy...feck knows what her percentages are
I then mate her to a collie whippet Greyhound type....I'm not 100% on his percentages but I think he was more likely 3/4 whippet grey ....with just a 1/4 collie...
