Can anyone recommend a good dog training and obedience video for labradors.

I'd recommend the Ian Dunbar series.

There are plenty of Obedience videos around by such people as Mary Ray and Silvia Bishop but for a pet dog I would not rule out Stan Harvey's "Gundog Training the young Labrador Retriever". You might not be interested in gundog work but I bet you find it interesting! (It even has a section on jumping! ;) )
