Dogs first hog zero interest

You need a small hog and build a rope sack or a wooden box with no wire to break teeth and get them used to siccing the small hog. Lots of times I just used a raccon in similar sack or trap to get them fired off at baying game, it prob help for sure if you had a older dog to help get there interest up in the hog, dont put them inside a pen with a hog until you get them baying a trapped hog or coon. You cn ruin them right here if you dump them inside a pen with big sow or boar that whips them bad, under 20 pounds or no more than they weigh, I would not even let them bay a big hog from outside a pen unless they were in a truck bed dogbox or something where they could nto get charged the 1th time they see a hog. Practice, Practice with small hog and teach them sic sic sic get that filthy hog son or something along those lines.
