Here I am 3,000 miles away in NJ on a business trip, and I get the call that no "mom" wants to hear- Kendall got hurt, and she's at the vet for x-rays. Turns out Kendall got a little exhuberant while playing with a bigger puppy at Puppy Play Day and ran into an I-bolt at full speed that was sticking out of the wall. C called to tell me she was there, but we're still waiting, many hours later, to hear their assessment. We heard it was a big day for emergencies at the vet. Sounds no different than human emergency rooms.
UPDATE: Many $$ later, we've found out that there's nothing broken. There's a lot of swelling, and Kendall's sedated right now so they could manipulate her shoulder. She was sent home for some loving and sleep along with some pain killers.
