Thanks again for all the reply's, here is an update on my dogs. I have a 7 year old short hair that will find an antler that I hide using his nose. He will turn from downwind as far as 30 yards and find the antler but when it comes to ones that I have not hid, that have no human scent, he would walk right over them at first but now that he knows the command find a bone he will search and pick up an antler that I spot. I try to stop right where I am at when I spot an antler and give the command so that he learns to find them on his own. He will find them and bring them back but he has yet to find one that I did not spot first. I do not think he uses his sight very much but rather relies on his nose. He also gets sidetracked with the grouse, rodents, porcupines etc.
I have a young black lab about 3-1/2 months old that I have worked with quite a lot on various commands including shed hunting and she will often find the antlers before my short hair because she uses her vision and can spot them quite well. She has retrieved a lot of the antlers that I have spotted after I give her the command to find a bone, she actually found one last week "a tiny two point" that I had not spotted and brought it back to me. She also picked up a two point set that I found yesterday on the trail without me having to give her any commands she brought the first one to me then went back and got the second one, granted these were only 10 feet from me but I believe she knows what I am looking for and what she needs to do. She is still pretty small and does not venture very far from me so she does not produce a lot but I feel that will change as she gets a little bigger. She shows so much promise and I will continue to work with her.
I kind of think that taking the two dogs together is hindering my shorthairs progress because the Lab is often close to me and will find any sheds that I see before the Short hair can get there, so maybe I will alternate which one I take.
