North Texas Dog Trainers stresses the real deal. This adds up to building a retriever that has no surprises in the field. A typical north Texas duck hunting trip can be in anything from dead timber to deep mud flats. The pup must be prepared to deal with this. Just because you have a hard charging pup does not mean they are up to the intro on a first hunt. Many retrieves in deep mud should be made so they can learn how not to expend all their energy as this clip shows duke retrieving a bird in very deep mud. The cover and mud in this clip show how he is learning to walk in deep mud. A young pup needs to see many different areas like this 4 month old pup in this picture.
