Got a call yesterday morning from a hunter who had shot a deer around 7:25 AM. After questioning him about the location of the shot, such as impact point, trajectory from stand, amount of blood, quality and quantity of blood, and deer actions after being hit, I told him I would come out but it would be after work. The temperature of the day and the heat were not exactly favorable conditions for tracking. We finally got to the location and started about 5:30 PM, 10 hours after the shot. We tracked/searched for approximately 5 hours with no success. At times Rebel was on the track verified by blood spots but other times she would appear to be on the track but would venture off and we would have to go back to the last blood spot and restart. It was evident that after the sun went down and the humidity and moisture levels came up, she was more consistent and the blood was easier to spot by flashlight. In hindsight, I believe I should have just waited another couple of hours until dark to start. The lack of visibility would have been offset by the improved conditions and been easier on the dog and handler. The last blood was found 600 yards from where the shot was taken. There was no clear bedding area where the deer had stopped, and even though the blood was consistent, it did not appear to be sufficient to cause death. All in all it was a good training opportunity. We all concluded the deer survived and not recoverable so I do not look at it as a failed attempt. It gave me and my dog a good opportunity to track real world. I believe if the shot would have been more lethal and the deer had expired, it would have found without a tracking dog. Rebel got some work, but most of the tracking was done/verified by sight.
