Did you ever try leaving a vest on Festus while he was in his pen. I've heard of people doing this with their catch dogs to get them used to it. Might have to try a boar bib if that don't work though.
No i never tried it. I just let him run without one. he would get cut every now and then, but he would be caught on the opposite ear of the CD, and the CD would be cut up and Festus wouldnt have a scratch.... Truthfully it suprised me he never got cut bad or killed, guess he just new what he was doing!
