On a lighter note:
Although my mother kept (and still keeps) her house spotless, she has never expected anyone to remove clean shoes in the house.
However, when I was in my teens we got a dog, a predominantly white collie cross,
and once or twice, when she was particularly dirty after winter walks in the muddy woods, we did rinse her feet in a bucket of water before going into the house.
One day, after another walk, she must have decided that her feet were dirty enough to need a wash, even though we hadn't rinsed them, because as soon as we walked into the kitchen, she went over to her water bowl and rinsed both front feet in it, one after the other!
Anyone else owned a house-proud dog?
