I have a 15 month old lab that has been hunting all season and has been doing great. today we hunted a large, half frozen pond with ice around the edges and he just flat out would not retrieve the ducks. He really did not want to get in the water. This is not lack of drive or training so, with all due respect, those are not the answers that I am looking for. I played with a dead duck with him for a while when we where done hunting both on dry land and throwing it in the water. He was as thrilled as ever to pick it up off of the ground but wanted nothing to do with it in the water. I was able to force him to it in the water but he certainly did not want to go. Any suggestions on what we might try to get through this? I live in montana so over half of our season is very cold. Thank you for any help!
