We don’t train dogs to be “friendly”, we train dogs to be “invisible” in public, meaning the dog will focus and follow the human handler at all time in public. Such a dog will not go up to bother other strangers, will not drag the owner to say hi to a random dog, will not pull the owner so he can sniff the goods on the shelf; such a dog does not care about other dogs, people, children more than his human. He knows where his priority should be, he has the maturity and self discipline to make the right decisions and he will always view his human as the most relevant being in the world. Such a dog can be taken anywhere without problem. He is invisible as he never bothers anyone in public (No barking, no jumping, no lunging...). He is very well received by the public because he is well mannered and well behaved. He is reliable because he listens well even around heavy distractions. Such a dog is a great companion and a true delight to have. He will receive lots of compliments and is always welcome by everyone, everywhere. Such a dog is not “friendly”, he is much more than that — he is “invisible”. 

Hope this makes sense.

Thank you.
