I don't think anyone can make that decision, except you yourself,none of us are living with Sasha,and you have to make choices for her, she has only you to rely on,i think you will know in your heart when the time is right.

For me personally if their quality of life is very poor and they are suffering i would make the choice to send them to the RB,but i must stress it is purely your decision and your's alone and none of us are here to judge or can judge, take care. HUGS
