I just don't let mine touch the Floor at all...
In fact, I lay a Towel down in a Shopping Cart,
put both of them in it, AND, tie them in via their
leashes/harness'.
I just can't stand the idea of them touching the
dirty Floor, other "deposits" or another dog's nose
or another area for any reason.
Seems like it would be easer just to leave them at home, but...
AWWWWW I just can't do that, GOTTA take um with me.
