The family should walk the dog about four feet from the highway and walk him in one direction for a while, and then the other. This builds up the dog's confidence and takes away any fears he may have of the highway. The family should also take the dog for a ride in the family car as often as practical to prevent him from becoming carsick later on. A Leader Dog is not trained to protect his master. Aggressive behavior towards people or other dogs is grounds for rejection.
Some dogs are happy only in their own surroundings.
A Leader Dog travels a lot and should be relaxed and content in a strange environment. This is overcome by walking the dog in strange areas often and by letting strangers handle the dog. The program also seeks donation of puppies and breeding services.
