I don't know anyone with a tracking dog but can tell you from experience look at a water source such as a water hole, creek, etc. I have found deer laying in a creek after it was shot. deer get a fever when shot and need to drink often. Mon. night my grandson a 10yr old mentor hunter shot a 4pt. his 1st buck with his other grandfather in the stand with him. On Tue. morning 4 of us did a grid search and found nothing. I started looking from a ravine where a creek ran and about 200yds I found the buck laying in the small creek. I am on the left of the Pic. and his other grandfather on the right. the smile on my grandson's face tells the rest of the story. P.S. I found my son's 1st 6pt. buck the same way look for a water source.
