I have been told that it is not a good idea to feed yorkshire terriers liver as they react badly to it long term (does something to their own liver?)  does anyone know if this is true and thanks.

i would not give mine liver i have tried on occasion some years ago as a treat  it made them very loose  it went right through i keep to the dry food i personally would not give my yorkies liver again i have never heard that damages there liver though
