John, Diesel from my perspective is part of the best batch of small musterlanders my wife ever bred. Her abilty to figure out a dog IMO amazing in that she had whispering abilities with animals (no joke). Some things I saw her do with training defied explanation. P.s. Diesel was the last dog that left the kennel when she sold that litter. Our dear departed friend Henry came up one day unannounced, We heard barking outside the house and investigated Hank was sitting there with Diesel in his arms, He said I need to have this dog and I want you to train it (my wife Tracy). From my memory the last dog she got done all the way. Keep him close he is a good one....
