From commentor Michael:
This is Lucy. She is three now. My fiance got her when I went to Iraq. (I am a cat person, nominally, so this was the ultimate outflanking maneuver) Lucy was six months old and 45 pounds then; the shelter estimate she’d grow to be 90. She’s a Boerboel (South African mastiff), probably (some kind of mastiff, certainly). She’s also the sweetest girl in the world, totally content to lie on her back and accept belly rubs virtually all day. A stranger’s just a pettin’ you haven’t cajoled yet.
Looks like Lucy has your number, sir…
