They respond very well to positive reinforcement, but do not answer well to any sort of harsh correction or heavy-handed training methods because they are sensitive little dogs which in short could well result in a dog becoming shy, withdrawn and timid. It’s important to offer high value treats when training a Chorkie and to limit the amount of rewards they are given to prevent them from putting on too much weight. It is far better to offer fewer good quality rewards rather than lots of cheaper, lower value ones when training any sort of very small dog.
