Chugs are smart little dogs and in the right hands they are easy to train. However, their training and education must start early and it has to be consistent so these small dogs understand what is expected of them. Just because a Chug is cute and small, does not mean they should be allowed to get away with things that larger dogs would not be allowed to do. If a Chug gets their own way a little too often, it can lead to all sorts of behavioural issues and this includes them developing “small dog syndrome” which can result in dogs becoming neurotic and harder to handle.
