Bad news is Rosie tore her other ACL. As the vet said said, at least she's run out of ligaments to tear.
She's back to full exercise now; went for her first solo run through the snow-covered pasture. I walked a little over half a mile. She went considerably further.
The good news is I've kept my weight below 130 all year so far. Scale said 126, most recently. Lowest I've weighed in years! It's mostly from moderation - less alcohol, less food. Better food. Certainly having been walking much this winter. Iowa is on the southern fringe of the polar vortex thingie and the temps have been brutal. Even Rosie's feet start hurting when it's in the minus teens.
