Once I got KAI to  "ignore distraction" - HE SHUT OFF THE OUTSIDE WORLD.   

The beagle is another story - He was a fear biter - I was hesitant to show this video but this dog was ready to be put down and the owners were present and we discussed what I was going to do. it may look cruel but This is not the only method I used and again I saved this dogs life and these clients are my best references - call and I will give you their info so you can hear for yourself. In some extreme cases where dogs are considered 'Untrainable" the answers aren't pretty. A novice trainer might say " Find a gentler trainer" this just show the limits of they're experience and their inability to fix this type of dog - some extremem  behaviors take extreme measures but always with the owner approval, their presence and only if the dog's life is on the line.
