Dog Training Tricks - Is Anyone Training You?

• Ok I'll put on my fire protection gear cause some PETA nuts will explode at my answer:
  BUT I train retrievers to respond to whistle commands in hunting tests. It is necessary for upper level retriever tests so I have experience with this.
  
  First you must TEACH what you want ..."COME" command be sure your dog is thoroughly proofed with distractions to obey the "come"
  Add you whistle pattern (I use 4 toots to come...one for a sit)
  Say 'Fido come" then toot your pattern.
  Rewards when they come
  
  Now once your dog has this down is is fully reliable (takes several days/weeks)...it is time to take him out with big distractions off lead and a fully charged e-collar. (in a safe area)
  If you toot and Fido does not immediately respond..one quick shock to get his attention. Then toot again and loads of praise when they come.
  
  My retrievers often work at 200 yards away from me. I MUST be CERTAIN they respond immediately to my whistle commands at all times...PLUS this can save a dogs life.

• Obedience training is the foundation for establishing a better relationship between you and your dog. Obedience training helps establish the owner in the role of "pack leader". Obedience will lay down clear behavior guidelines that your dog can follow. A well-behaved, obedient dog is more than just a pet of pride. The difference lies largely in the training, and good training can save a dog's life.
