I have had many dogs and have experienced many types of training. I have seen up close what works for some dogs doesn't work for others. On my crockpot yorkie Teddy he would bark non stop. He went to two different training classes and still would bark non stop. Then the citronella collar - no help he loved it!. The shock collar - because he is over 13 lbs we use it. BUT if the door bell rings shocked or not he would bark and howl!
The vet had said we could remove his vocal cords as a last resort.
He would bark in his sleep until the bark collar!
Tried Cesars method with my husband ringing the door. IT WORKED!!!!! He no longer reacts if the door bell rings and with a dead battery he think the shock collar still works. If the door bell rings he looks at me now like OK this is your responsibility - take care of it!!!!
Thanks to Cesars method the door bell isn't an issue anymore.
I never would have removed his vocal cords but moving to the country or building him a sound proof room were thoughts we had
