It is an easy trick to learn, dogs and all other animals always relate things and if you keep repeating that same thing they link one thing to the other and see it as a message they come to understand what you mean only by looking at you.
Confused? I think it is the same techniek used for dogs that are trained to help disabled people as a help or service dog.
I don't know for sure because I never trained a service dog.
What I did do was rehabilitating police dogs.
I read in the news that the U.S police said they have to kill their drugs trained dogs but that is such a nonsense. read that story here
I rehabilitated police drug trained dogs that worked for narcotics and able to sniff explosives, even a dog trained to find dead bodies underwater that solved a major disappearance case. The dog was an excellent swimmer and loved the water but never wanted me to go in the water because then she would come to save me and wanted to drag me out of the water. To rehabilitate a dog like this is best to avoid the situation.
Another dog on narcotics had a long relaxed time with me on the farm and after maybe 6 mounts the police wanted to test him to see if he still would remember what he had learned. We set out a trail and from the moment the dog handler gave the command and the dog changed like he was back on duty again and followed the trail on the spot and perfect. Conclusion was that the dog was a perfect dog on the farm with lots op space friendship and a warm home a perfect family dog.
The last police dog I got was a very well trained dog and for a long time. She was the success story. She was old and needed to retire and a warm home. She scared me the first day she was in my home. She looked me like she was ready to jump. You can imagine the these dos live their life in a kennel sometimes they live with the handler but not in all cases.
She was there just looking at me and I had to avoid any eye contact with her this first day. She could only watch my movements and smell my body odor in her surroundings. When I went to the kitchen she followed me checking me out.
I kept talking to her and rewarding her for not being a police dog. It only took a few days and I trusted her and she trusted me.
We became the best of friends and she stayed with me till her last breath. The young police dogs I socialised and gave them their first basic training. They came to my home at the age of 5 week and stayed till they were ten months and started their police training.
Sometimes I was called in to work at the airport for exames of the dogs and their handlers. I had to pretend to be a passenger and had a suitcase full of drugs or the drugs was taped to my body and was closely watched by undercover police. They put me in a just landed airplane and I had to walk out with the passengers like I was coming home from vacation with the hidden drugs. It was up to the dogs to pick me out of the crowd and up to the handler to follow the right police procedural. So I have been arrested in public several times because for the handles this was serious stuff. When the dogs found me and the arrest was made a legion of undercover police step forward to tell everybody else watching that the event that it was just a practise.
Police dogs, no matter how they are trained can be rehabilitated If anyone makes you believe that they need to be killed you know that they lie.
