back in the 1980's this friend of mine had a red bmc that was a hog dog at 18 months old. He got him because the breeders didn't like him busting bays so he was a cull.
I saw this dog keep a 275 pound plus boar shut down for a good while. The hog was sitting down protecting his jewels and wouldn't run. The dog was smoking some ham and mtn oysters...

Same dog a week later bayed a large sow and when we caught her he rolled out again with 3 loud chops and then the next time you heard him he was bayed. In about an hour or so we caught 4 big hogs from the same herd with him and an airedale we were using for a catch dog. They each had an ear on the hogs. I told the kid that was helping me to catch the dog while I caught the hog and he missed and the dog went and bayed again. We finally called him off and leased him. On the way back to the truck he struck about 3 times off the leash but we didn't let him loose.
He was a tight bay dog and easy to look at.
