I was just telling a friend about Roxie in the car and how she looks so much like a whippet when she stands and sticks her head out.
So I googled again, another attempt to find a dog that looked like her. I've found one that could be her brother. It's incredible. He's listed as a terrier x whippet which was my closest guess for Rox, but I think this is good enough proof!
I've included some photos of them both. Try and figure out who is who!!
