Aussie pups have generally shown up here looking fairly substantial and quite furry. Sweep showed up looking quite tiny and "unfuzzy". When I took him outside the first few times he started shivering pretty darned quick.
My maternal instincts kicked in. I sprung into action...and made him a sweater. I made him wear it - once. I think he wanted to die of embarrassment. Anyway, I told him that if promised not to look pathetic outside I'd promise not to make him wear it again. I swear he's been fine ever since!
