Craig, i've thought about tying a piece of mule tape to him and pulling him back in with the hog... do a little "hog fishin"!
One time I had 2 dogs caught on a Javelina in a 10in pipe in the middle of a 12ft section. I had a pit at the time and I clipped leads to her vest and sent her in. When she had a good grip on the Dirty Rat I pulled the whole pile out and stuck the Javi before his head cleared the end.
SO that will work
