Any dog trainer here???

So I have this pup that seems to be good at tracking blood trails. So what I want to do is train him to track a deer blood trail for a deer that is shoot and hard to find. So how does one go about doing this?? I have ideas but never tried to train a dog like this so maybe could use a few ideas
Thanks

Old, I once shot and lost a big buck while hunting, it got to dark to find it. I was able to track it to a very large swamp. It was to late to attempt the swamp. I went in but soon lost the blood trail. With my dog 40+ miles away I decided to tackle the swamp the next morning. I loaded up my dog, she was half Pitt bull 1/4 Rott,1/8 German shepherd,1/8 collie... I do like mixed dogs. She was a very smart family dog. she was about 2 years old at the time.

I went back to the place I shot it. I put her on the track, I tracked it along with her. I kept asking her where'd it go? Soon she was tracking it on her own. with me behind her. I knew she was on the track because of the tracking I had done the night before. She made every step right, She was tracking it like a pro.

We hit the big swamp, right where the buck had entered. We were going through the thickest thicket. I had her on a lead. We went though at least two other peoples land and then into a third owners land. We were still in the same swamp. She took me to the wide heavy mass. wall hanger 6 pointer. She did all this without barking once.
Of course I told her what a good girl she was. I took her home. Then I went back for the deer. It was hard getting it out, but it would have been impossible to get her and the deer out at the same time.

What kind of pup you thinking of training? How old is it? If it were me, I would get it to track anything by saying "where'd it go or where's the deer" I used to train coon hound pups by having someone drag a dead one on the ground and then putting it in a tree. Then I would go out with the pup and get them tracking the coon. When they figured out what I wanted tracked and could track it, Then The person would start pulling the coon by a rope up the tree only to sling it out and let it land away from the tree and then go to another couple tree's. I was teaching it about how a coon will "Tap a tree" You get the point.

I wish you luck... And by the way The deer tracker never turned into a deer chaser. I could of had her track anything or anyone. "I like's my mutts"...MTP

So I never had any luck with my Golden Retrievers. So I don't know the answer to your question.

I rely mostly on reward with as little punishment as possible. To demonstrate how I reward in circumstances that some people punish. Useing an e-collar to break car and trash chasing. When dog starts chasing I administer a mild annoying but not painful stimilation (level of stimulation varies from dog to dog). When he quits chasing he's rewarded because stimulation stops. The dog come's to believe he is turning off the stimulation by his action. Know each dog's favorite game or treat for use as reward. To track wounded deer,drag a fresh hide(pieces can be frozen for later use.) When dog finds it throw the ball,praise him or give snack. It's a good idea to wean from treat or game and use praise if possible but many dogs respond so well to them it's wothwhile carrying treats or ball from now on. As time go's by inrease difficulty by going through a herd of livestock,cross stream,increase time between making drag and putting him on trail,taking another dog along as detraction and so on. Once trained tune him up now and then year round. Try to vary how drag is pulled by useing different people,4 wheeler,horse or tractor,otherwise he may be learning to track you.
Here's a twist on training. I rewarded a pointer pup by feeding him heads off quail he reteived and he learned that quail which had been handled were his to eat.

Check youtube. There is more than likely something there

I have dial up so you tube is like trying to fly a kite in a thunder storm not going to happen
