I feel your pain. Our two have warn all the grass away, so if it's warm out, it's just mud. Luckily you have tile and hard woods, we have carpet everywhere, so we have some dirty carpet right now...ick.
That is what my tile looks like today too. We have the doggie door and a backyard that no longer has grass. So when you add the yard with no grass and rain you now have mud that the girls just think is great to play in and then if I am really luck they try to bring some in with them... all of that with white tile... YEAH!!! 8O But of course all i do is laugh.
That looks like my floor too!!! We have red clay and that stuff is awful....I have a huge rug at the back door, but Angel flies thru there so darn fast I don't think her feet even touch it :lol: I think it was the "phantom dog" Alicia, Lola looks waay too innocent to have done that :lol:
