got a 4 year old whippet and now have a 7 month old 3/8 5/8 bull cross. Couldn't care less about numbers as long as the dogs give it their all. And i think both Whippet and Bull X owners will agree that both breeds do that. Pup is learning alot off of the whippet at the min so will see how she comes on, and they both compliment the ground I run. But not sure what the combination of these two breeds say about my penice size.
