Well, hello there! I would be the resident Greyhound owner here although Seqqy's dad pops in here every now and then. Are you sure your pup is a WhippetXGreyhound? She looks rather stocky to be a Whippie/Grey mix. I'd also recommend you buy her a martingale because she will get herself into trouble with a regular buckle collar. Where'd you get her and how old is she? She's absolutely precious!
