Where you see the instrument poking out the other end is where I had felt a little bump the night before, I should have known from his reaction that there was something going on besides swelling. The next pic is of the make shift drain they put in. We used a finger from a rubber glove as a proper drain wasn't stocked in the truck....hey whatever works.
After the drain was in a few stitches at either end to keep it there and done... good as new.
So in spite of my stupidity, and good timing, Jake is already moving around better and should make a full recovery.
