I don't mind a dog that opens after the hog breaks and they're right behind it... lot's of "dead silent" dogs do that.

By then the race is on so to me it doesn't matter.
What I don't care for is a dog that opens when it hits a track. I've always looked at it like this... you turn a dog loose at daylight and the hog is bedded say 1/4 mile away. The silent dogs trail him up to his bed and the open dogs are going to let the hog know they're on the way. I've bayed and caught plenty of hogs this way, right in their beds. That's how i've always looked at it... and yes, i've hunted with several wide open dogs over the years.
