He looks to be about the same size as my dog Hooch. He is Staffie X Bull Mastif X Pitt Bull. He's a big friendly lump our Hooch. He's also very excitable but never chewed anything, not even when he was a pup. He's 7 now and weighs about 5/6 stones so isn't as agile as he used to be. We should have called him Forrest Gump I think cause he's daft, clumsy but very loving LOL. We have a glass coffee table and he's always cracking his head on it. And no he's not going blind, just doesn't look were he's going LOL.
