I bred a few litters of West Highland pups years ago and had 3 Adults who were all toilet trained to GRASS!! Louise hasn't a clue, she has a garden and should be taking that pup out onto the grass especially in the morning and as the pup pees ,repeat a small word like pee-pee etc, as he pees. Eventually he will associate the word every time he's on grass and become toilet trained to grass. Ya you've to soak it up but not stand on it that it sticks to your shoe and u in turn wear that pissy shoe all over the house
