Dear Eric: We were visiting my sister-in-law, which we’ve done quite a bit. We got home and a few days later I called her. She told me she believed our dog peed on the carpet right outside the bathroom door. She was looking in the bathroom mirror and noticed a small yellow spot.

She said she didn’t smell it or touch it to see if the carpet was wet but cleaned it up. Of course, I was mortified, and said “oh no, we won’t be staying with you anymore.”

She said he probably did it when I was down using that bathroom. By the way she is a clean freak, so to speak.

I am having a hard time getting past this, especially since she didn’t smell or touch it, the carpet is speckled brown. We have visited many times with our dog. Any input would help.

Dear Visiting: Don’t banish yourself just yet. It doesn’t sound like your sister-in-law is holding this against you. Though she may be a clean freak, it also sounds like she’s taken care of the offending spot, pee or not, and so the state of cleanliness in her home has returned.

These things do happen from time to time with pets. If they didn’t the very large, and comprehensive line of carpet cleaning products with dogs on the label would be sunk.

You might call your sister-in-law back to check in and see if there was any additional cleaning that needed to happen. If so, you might also consider paying for it. But it sounds like it wasn’t a huge mess to begin with and now it’s just a memory.
