Is a 5 year old lab to old to start to train to retrieve?
That is the straight story. No frills. None needed.it depends on the character of the dog and his desire to retrieve. A 5 year old dog has a bunch of baggage that will usually handicap his ability to reach a high level of training. So, take it one step at at time, beginning with simple retrieving. Continue up the ladder of skills and commands until the dog tells you, "no more".
