Barometer?

When I was bird hunting all the time I kept a log of all the weather conditions. Barometric pressure, temp, wind, direction, humidity, ect.. I did this for an entire season and I was running and training lots of dogs back then so it was not just a dog or two.

Here is what I found. Dogs cannot scent as well on a south wind, east is next worst, and north and west are the best. I don't know why but I know it is true.

When I was helping out at a hunting camp we were working about 35 dogs per day. I have seen dogs that did not smell birds well in perfect conditions. I have also seen them smell in the absolute worst conditions. I have seen conditions change in a couple of hours dramatically. Don't ask me what changed because I don't know. All I do know is that 4 dang good bird dogs did not do well early one morning in a particular pasture. The brids were there because we had several stop to flushes. We put 4 more dogs in the same pasture and they did great. Then we put the first 4 dogs back down and they were simply outstanding.

I guess that is what makes dogs so neat.
