Is it flooding?

I’ve seen an unbelievable thing when I get out from the bed room. I thought there is a flood inside the house when in fact there is no rain and if there is rain our roof is sealed. Sigh! It’s positive that it’s the pee of our dog. Well, that’s the consequence of having a dog and doesn’t have a puppy door. But if we have a puppy door, it will be useless since our dog can’t get out by herself. She needs to be carried outside the house and be carried back also. If she’s just sent real quick outside during the time she’s walking and walking, I guess our floor will not be flooding with pee.
