Thanks everyone!
wrenchman... i haven't really had much time for training in the last couple of years but I put her on a bear trail a month ago and she was on it like glue til she lost it. We were pretty sure the guy had missed but since we couldn't find any kind of trail I took Catria out with us. We put her on the trail right at the bait (there was no blood of any kind) and the guy said she was following exactly where the bear had gone after he shot. She followed the trail for over 100 yards, then lost it, but it had been really wet the night before and had just stopped raining when we left the house.
After she lost the trail, on a large rock out cropping, I got her to try a few different trails leading off the rock but she only went a little ways before she stopped and started winding the air. I'd get her to come back to me on the rock and try another. I'm sure she was on the right track but with all the rain the scent was washed away, specially since he'd missed (we know that for sure now) and there was no blood to leave a decent trail.
ps... I have another one to tell ya bout later, after it gets outa the bush and get some pics. Weeeeeee!!!!!!
