It may or may not be easy to teach your dog to fetch. If you are persistent however it is possible. You should first decide what item you are going to use and be consistent with that item. You should begin with your dog by your side, throw the item a few feet in front of you and say the word fetch. If the dog does not go to retrieve it then physically take him there with encouraging words. As he does begin to go after the object always offer him a treat when he returns it to you. You can gradually increase the distance you throw it as he learns the command. Good Luck!
