Shes 25" to the withers and about 65 pounds. Im sure she is part bully breed, but what else I couldnt say.
She and Zaphod are about the same size, then. He's still got a bit of growing to do, though.
Anna, Sizzle hit the nail on the head. Zaphod is probably naturally rather flat-footed. (not badly, but not high on his feet like a Doberman would be.. for an example, Leah could you post a pic of Ilsa or Ronin's feet so Anna can see?) But he is going to come up on his feet a LOT with a better diet. I think the reason right now that they're so awful is because he spent so much time on a concrete floor, jumping up and down and putting a ton of impact on those feet. Now that he has a soft crate to rest in and sand to run on, his feet are way better.
Another thought on feet. I find that dogs who need to be able to move at great speeds and turn quickly have somewhat looser feet. Eve, for example, has pretty average rear feet, but looser (not splayed, just longer toed) front feet and flexible pasterns. Like a built in shock absorber.
