Awwww Tug!! He's just changing so dramatically right in front of my eyes. I think the same way about mine but when I see other people's it just more obvious. Mine don't turn 7 mos til the end of this month. I so wish we lived closer so we could get them together, that would be a blast! Tug is built a lot different than Yukon. Tug has those long legs and like you said, he has yet to fill out. Yukon on the other hand is all bulk and not lanky, at least not yet. He is starting to get his 'mane' too.. is Tug? He looks like a total sweetheart. He is very pretty in a manly sort of way.
