Hi there...yep it sounds like you have a problem!!!!!!!

Firstly tell us a bit more about your yorkie..i.e. age..how long you have had him..and if the barking started with any particular thing...e.g. thunder or anything like that and if chester barked from the beginning or when......Have you had him checked out by the vet.. to see if there is any underlying problem...(our yorkie only started consistent barking when he was older and that was due to health problems.))

Come back with some more info about chester and we'll go from there.
