Yes, this surprises me as well. I believe the most humane thing may have been to end this poor dog's life but for Animal Control to make that decision over the phone is what is most bothersome. I'm sure your description of its wounds were accurate but what if the next person that calls overreacts to a little blood or a compound fracture for example. Without AC taking the time to investigate, a completely treatable pet could be put down, possibly by a less than competent person. This dog may have been homeless but no one knew for sure. If nothing else AC should have come out and scanned for a chip, written a report in case someone was looking for the dog, and at the very least, taken on the job of disposing of the body.
