All the cotton pickin time! Weird isn't it.
I go you one stranger, I saw my Ratty do it across a shallow section of a moving bayou. You know dang well that water didnt smell, its moving!!!! All I figured was the boar must have left scent on the bottom and the water was lifting it as it rushed over.
one thing I do know is sometimes the dogs are not running a track but running off of wind currents. The dogs appear to be running a track but might actually be 20 yards on the downwind side of the tracks (crosswind).
I can see the dogs picking up the smell if the water current is moving toward their direction. If the water current is moving away then it is possible that the dogs will look for the track and get down wind from it and then they will jump in the water and follow the scent...
not saying this is what is happening but that makes the most sense to me. also, the current always appears to be going faster that it really is...
