Dutchess - it IS hard. But, I am letting her go as far as she can, on her own - (no matter how difficult) since I read your post (and other’s) this morning.
She has never been a ‘spoiled’ dog (I don’t think) and she is very obedient and always wants to please. She almost looks ‘proud’ when she finally reaches ‘that special spot’ to go potty. Of course, if it were me, I would potty wherever I was, if my legs were so weak - but not Lindy - she drags herself all over the yard to find that perfect spot. (And, of course her Mommy stands there with tears in her eyes - wanting to help.)
