Yes high protien diets and wallpaper both seem to be really bad for Yorkies... But here is my dilemia for Wed. when we all go back to work for the first time and they are alone for 11 hours. If I keep them in the kitchen which they have never be restricted to they will probably eat the wee wee pad since they have eaten that before. If I let then have the kitchen and family room as they always did they may eat the wallpaper and the wee wee pads. So I am thinking perhaps they wont be so mad if they have their usual space and with a little luck they wont eat anything that is bad for them. The low protien diet stays in place for life and with Gods blessing no one will get sick again. You never know how deep your love is for these little guys until something happens to them. Once his little brother turns 1 it will be easier on the food side since he wont need puppy food any longer.
