He made it through the night and seems alert! Our canine patient may have made it through the worst of the wound recovery period. There was no rain last night, which is good because the dog was in no condition to crawl into his shelter and didn't want to be confined to the house.
Unfortunately, since we are heading out this morning, more info may be sporadic at best. He was remarkably paitent during his assorted treatments, only flinching occasionally as his wounds were dressed. I don't think he even whined, much less snapped at anyone.
