4 year old AB?

I had the same situation I bought a 3.5-4 yr old AB gyp that had never caught a hog in her life. I took her to the baypen and put three bay dogs in it and left her on the outside. She started going crazy when they were baying so I put her in there and she flew across the pen and bulldozed a 250 boar hog Knocked him clean off his feet! all ear the first time. I spend some time training her to go to a bay in the woods while I was training my pups and less than a yr she is one of the best catch dogs in the woods. This is what worked for me.
