i had a laguna whippet,similar lines to gnippers.blue 21 1/2 inches really looked the part.heavily muscled and well trained .couldnt catch a rabbit in a telephone box .not slagging whippets off or the laguna strain in general but the one i had was no good for what i wanted it for which was catching stuff.i put a lot of time into that dog and was sad to see it go.good luck to the boys and girls out there with there whippets,i am sure there are plenty of good uns out there but the one i had just didnt have that do or die instinct in it
