How old do y'all show pups their first pig?

i used to raise all my pups free range on the farm and they saw pigs and cows and ckickens and yotes [ some didn't make it back from them ] but i would let em run the farm and only pen them up when the cows started paying attention to them or i feared they may finally dig into or go over the hog pen . i can't raise them like that anymore so it has slowed down the starting age on my pups now i wait until they are around six months old and some of the puppy has worn off them . but the free range pups would be baying and trailing at a very young age , maybe 3 to 4 months old and i have bayed wild hogs with pups that age on the back side of the farm during training sessions , they would leave the drag trail and get on a hot wild hog track that was in the swamp checking out the caged shoat i had set out . so just depending on where you are and how much time you have as to when you want to start them is up to you . the catahoula hound crosses i raised were baying and trying to catch 80 to 100lb sows at 3 1/2 months old . just watch your pups when you let them out to play and decide for yourself no right or wrong answer or time to start .
