Food is also left on the ground around the jumps and the dogs also ignore this. It takes less training to do this type of refusal than it does to poison proof a family pet or personal protection dog. Dogs can learn that the only place they accept food is out of their own food bowl. If that food bowl is not left in an outside dog run they should not eat any food left in a run or a back yard. The initial concept is the same.
Food is left in the front or back yard in a dog bowl.
Get down wind of the food bowl and watch for when the dog gets odor. We don't want to kill the temperament of our dog her. It's also important to vary the type of treats and the location. Use table scraps, steak bones anything you can think of. A strong word of caution here, when you use the anti freeze it is absolutely critical that you pick up every piece of food that was dipped in it after you are done training.
