I guess we'll open our family blog with the best news ever:
After being gone for four long days, Laszlo returned, but with serious injuries (if he hadn't already been neutered, one of the lacerations would have neutered him). We did not at first realize how serious it was because he seemed fine. The vet who performed the surgery was shocked when the x-rays came back. She said that Laszlo had the strongest constitution of any dog she has ever seen (and considering she works at the ONLY emergency pet clinic in Tucson, that does mean something). Apparently, any other dog would have clearly been suffering with the injuries he had, but he seemed almost unaffected.
He's now recovering in his circus cage in our family room, where he'll be stuck for at least another week, until his staples come out and he fully heals. In the meantime, we're enjoying the great reception we get from his cone.
